, 2000), Grace et al. (2001) reported that subcutaneous injection of NSAIDs completely eliminated the hyperalgesic response elicited in rats by ischemic stimulation of the tail and suppressed the increased prostaglandin formation in the brains of the animals. However, the relief of hyperalgesia was short-lived and corresponded only to the first phase of the (spontaneous) hyperalgesia ( Scheuren et al., 1997). In addition, PGE2 has been found in microdialysate of the spinal cord after

injection of formalin in the paw of the rat ( Malmberg and Yaksh, 1995 and Scheuren et al., 1997), MK-8776 mw and its production was antagonized by systemic injection of paracetamol ( Muth-Selbach et al., 1999) or by intrathecal injection of other NSAIDs ( Malmberg and Yaksh, 1992). Direct evidence for a spinal antinociceptive action of NSAIDs derives from observations made in patients and animal experiments. It has been reported that intrathecal injection of acetylsalicylic acid, salicylic acid, and indomethacin depressed the nociceptive activity that was evoked in thalamic neurons of rats by electrical stimulation of afferent C-type fibers in the sural nerve ( Jurna et al., 1992). The development of nociceptive pathways is an activity-dependent process (Fitzgerald and Jennings, 1999, Fitzgerald and Beggs, 2001 and Beggs et al., 2002), and thus, abnormal activity such as that generated by early opioid exposure may alter normal

synaptic development producing changes in somatosensory processing and behavior that would

not occur in similarly exposed adults. Our group has demonstrated that neonatal rats may be more sensitive to low doses of morphine because there is selleck chemical extensive re-modeling of opioid receptor expression in the first 3 postnatal weeks (Rahman et al., 1998, Galeterone Rahman and Dickenson, 1999 and Beland and Fitzgerald, 2001). For example, at P14 spinal μ-opioid receptors (μORs) are limited to the dorsal horn, whereas they appear throughout the spinal grey matter at P7, and the density of binding is seen to decrease in the first 3 postnatal weeks, with peak binding at P7 that then falls to the adult level by P21. This abundance of μORs in early postnatal life could explain why exposure to morphine for 7 days, from P8 to P14, produces analgesia instead of tolerance (Rozisky et al., 2008). Thus, the greater expression of μORs at P7 in comparison to adult rats suggests a more widespread effect of morphine, acting both directly within the spinal cord and indirectly through larger termination profiles of primary afferents (Nandi et al., 2004). This, coupled with the over-expression of excitatory amino acid receptors, at the primary afferent-spinal cord synapse, supports a potential role for μORs in the normal maturation of nociceptive circuitry, and hence, disruption of this by exogenous administration of opioid agonists may have detrimental consequences for the maturation of pain circuitry (Thornton and Smith, 1998 and Thornton et al., 2000).

The survey lasted 12 months and the patients were enrolled

The survey lasted 12 months and the patients were enrolled

between November 2007 and October 2008. Ongoing follow-up will continue up to 36 months. Patients’ screening consisted with demographic characteristics, current medical treatment, neurological evaluation, indication for PFO closure and RLS evaluation. Imaging with cardiomorphological data, different devices and possible complications were indicated during the procedures. In the post-procedural phase early complications, length of hospitalization and treatment at discharge were described. Follow-ups were within the 6th, 12th, 24th and 36th month. Data regarding cardiac imaging, residual RLS, neurological recurrences and/or cardiac extra-cardiac complications were specified. Most subjects who underwent PFO closure had a previous history of TIA/cryptogenic ischemic stroke (∼80% of check details patients). The remaining indications were consistent with migraine with aura, other events of paradoxical embolism as myocardial or retinal ischemia, residual PFO after a previous

procedure, platypnea–ortheodoxia syndrome, neurosurgical procedures in sitting/semisitting position, diving, thrombophilic status and asymptomatic patients with neuroradiological ischemic lesions. Fifty Italian cardiology departments accepted to participate. Forty of them enrolled at least one patient in the registry. 1035 patients (mean age 46 years [range 5–75], 619/1035 [60%] females) were included in the registry. PFO diagnosis and right-to-left shunt (RLS) were assessed by contrast-enhanced transesophageal (cTEE) and/or transthoracic echocardiography (cTTE) and/or transcranial Doppler (cTCD). RLS was assessed selleck kinase inhibitor in a visual semi-quantitative method by cTEE and cTTE: RLS was find more diagnosed if at least 1 microbubble (MB) appeared early in the left atrium either spontaneously or after provocative manoeuvres, thus indicating no shunt if no MB were revealed up to a severe shunt if >20 MB occurred. cTCD methods regarding RLS diagnosis were previously described [9]. cTCD was performed according to the standardized procedure agreed on in the Consensus Conference of Venice [10]. Briefly, the

total MB count consisted of all MB detected during a time interval of 20 s or less after the appearance of the first MB. The proposed classification is as follows: small (0–10 MB), moderate (>10 MB, without shower or curtain pattern), and large (shower or curtain pattern) RLS. All our patients who exhibited RLS of 5 or more MB were considered to have a positive test result [11]. Aneurysm of the interatrial septum (ASA) was diagnosed in the presence of atrial septal excursion greater than 10 mm beyond the plane of the interatrial septum in the presence of a base width greater than 15 mm. ASA was associated in 423/1035 (41%) patients. Intraprocedural monitoring was assessed by using TEE and fluoroscopy in 70% and intracardiac echocardiography in 30% of subjects.

By creating paullones able to bind to ruthenium(II) and osmium(II

By creating paullones able to bind to ruthenium(II) and osmium(II) arene moieties, we expected to reduce the encountered problems markedly. Moreover, synergistic effects and the differing targets of metals and ligands could be an advantage for inhibiting cancer cell

growth. Indolobenzazepines with the general formula [MIICl(η6-p-cymene)L]Cl (L = L1 or L2; M = Ru or Os) ( Fig. 1) have been synthesized and characterized previously [13]. These substances have shown their potency in a cytotoxicity test in three human cancer cell lines, selleck chemicals with IC50 values in the lower micromolar range. Hydrolysis behavior and reactivity to 5′-GMP were also reported. High cytotoxic activity was the reason for further studies on PCI-32765 chemical structure their impact on human cancer cells. Because of the known Cdk-inhibitory activity of the metal-free paullones, inhibition of Cdk2/cyclin E was also investigated in a cell-free assay with the metal complexes. Effects on the cell cycle were quantified by flow cytometry, and the metal accumulation in the cells, inhibition of DNA synthesis and induction of apoptosis were

compared to cytotoxic potency. Compounds 1–4 were prepared as described previously [13]. For all experiments, the compounds were first dissolved in DMSO and then diluted in medium/buffer as appropriate. Flavopiridol was kindly provided by Sanofi-Aventis. CH1 (ovarian carcinoma, human) cells were donated by Lloyd R. Kelland (CRC Centre for Cancer Therapeutics, Institute of Cancer Research, Sutton, U.K.). SW480 (colon adenocarcinoma, human)

and A549 (non-small cell lung cancer, human) cells were kindly provided by Brigitte Marian (Institute of Cancer Research, Department of Medicine I, Medical University of Vienna, Austria). Prostate carcinoma cell line LNCaP, mammary gland carcinoma cell line T47D as well as the gastric carcinoma cell line N87 were purchased from the American Type Culture Collection (ATCC). Cells were grown without antibiotics in 75-cm2 culture flasks mafosfamide (Iwaki/Asahi Technoglass) as adherent monolayer cultures in minimal essential medium (MEM) (for CH1, SW480 and A549 cells) or in RPMI 1640 medium (for LNCaP, N87 and T47D cells), both media supplemented with 10% heat-inactivated fetal bovine serum and 4 mM l-glutamine, but only MEM supplemented with 1 mM sodium pyruvate and 1% non-essential amino acids (from 100 × ready-to-use stock) (all purchased from Sigma-Aldrich) without antibiotics. Cultures were maintained at 37 °C in a humidified atmosphere containing 5% CO2 and 95% air. Cytotoxicity in the cell lines mentioned above was determined by the colorimetric MTT assay (MTT = 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide, purchased from Sigma-Aldrich).

State transitions have not been documented in diatoms [5], and no

State transitions have not been documented in diatoms [5], and none are reported for the eustigmatophyceae. Instead, diatoms balance photosystem activity by quenching photon absorption by PSII as a result of de-epoxidation of xanthophyll pigments [10]. A direct comparison showed that this process resulted in 2-fold less generation of wasted electrons than state transitions in a chlorophyte [10]. Quenching in the antenna system also reduces damage to the photosystems,

which carries a high energetic replacement cost [11•]. Dissipation of excess light in photosynthesis is primarily achieved through non-photochemical quenching (NPQ). Different strategies have developed for NPQ in evolutionarily distinct classes of algae, including rapid rates of synthesis

or high accumulation of de-expoidized xanthophylls [12]. Xanthophyll cycling systems are apparently lacking Ponatinib purchase in phycobilisome-containing organisms and the Chlorarachniophyta [11• and 13], and NPQ in cryptophytes differs from other chromalveolates [14]. Differences in photosynthetic processes are likely to affect light harvesting efficiency, which ultimately translates into altered growth and product molecule accumulation. There are very few definitive analyses comparing the relative efficiency of the described diverse photosynthetic arrangements. Such information would not only aid in developing strategies for improved light capture in diverse classes of microalgae, but potentially in the development of artificial photosynthesis approaches. Carbon fixation in the Calvin–Benson PS-341 cell line cycle is catalyzed by RuBisCO, which has a low CO2-saturated maximum catalytic rate and competitive oxygenase activity resulting in photorespiration. To compensate, microalgae have taken advantage of different strategies to maximize carbon fixation efficiency. One involves the use of RuBisCO with improved affinity for CO2 and selectivity for CO2 relative

to O2 [15]. Cyanobacterial-type RuBisCO forms IA and IB (found in cyanobacteria and green algae) generally have a low affinity for CO2 and a low CO2/O2 selectivity relative to red algal-derived forms only IB and ID, however the latter has a lower turnover rate [15]. Kinetic and regulatory variabilities suggest that different forms of RuBisCO are evolutionarily selected to function optimally in different subcellular environments [16]. Carbon concentrating mechanisms (CCMs) are another way to increase carbon fixation efficiency, and these can be classified as being either biophysical (involving localized enhancement of CO2) or biochemical (involving specific enzymatic pathways). The biophysical mechanism of concentrating RuBisCO in carboxysomes and pyrenoids allows for regulation of CO2 delivery [17•• and 18•]. Cyanobacteria and chlorophytes rely largely on biophysical CCMs by transporting and accumulating bicarbonate and converting it to CO2 near RuBisCO via carbonic anhydrase [19].

Non-averaged sea surface images of a shallow are usually rich in

Non-averaged sea surface images of a shallow are usually rich in the footprints of meso- and submesoscale processes, which are due to a variety of forcings and mask the manifestations of resuspension. The two-fold discrepancy between the long-term average Loffwnav(λ) and Lonwnav(λ) indicates the probability of a broader range of ‘instantaneous’ radiances in daily images of a shallow and gives an idea of the errors in deriving water constituents from

normalized radiance without regard for the resuspension of bottom sediments. The latter is a multistage process whose stages vary temporally and spatially. This list is far from complete. To overcome these difficulties, it may be reasonable to confine the use of satellite data to images of a shallow obtained at wind speeds below Olaparib nmr 3 m s− 1. A comprehensive numerical model for resuspension

with data assimilation capability seems to be the most appropriate solution. Further interdisciplinary studies Dasatinib of relevant processes and phenomena are needed to ensure the feasibility of the model approach. The ocean colour data used in this study were produced by the SeaWiFS Project at the Goddard Space Flight Centre. The use of this data is in accord with the SeaWiFS Research Data Use Terms and Conditions Agreement. The authors are grateful to the anonymous reviewers for their helpful comments. “
“Water column conditions in coastal lagoons depend on a number of factors, including the balance of surface heat fluxes at the air-sea interface, the contribution of fresh water discharge or runoff, wind stress and tidal mixing (Simpson and Hunter, 1974, Simpson and Bowers, 1981, Bowers and Simpson, 1987, Simpson, 1997, Yanagi

et al., 2001 and Butanapratheprat et al., 2008). Positive surface heat flux and fresh water discharge strengthen the vertical stability, whereas tidal currents and wind stress increase water mixing and turbulence. However, these factors are modified in each area. Therefore, it is necessary to understand the controlling factors and their role in order to know the mechanism of water column stability in the area of interest. The Red Sea (Figure 1) lies in an arid zone where evaporation Interleukin-2 receptor is very high > 2 m year− 1 (Morcos 1970) and precipitation very low. Consequently there are no river discharges in the area. Many studies have been carried out regarding the surface heat fluxes in the Red Sea (Bunker, 1976, Bunker and Goldsmith, 1979, Hastenrath and Lamb, 1979, Ahmad and Sultan, 1987, Ahmad and Sultan, 1989, Ahmad et al., 1989 and Tragou et al., 1998), most of them referring to the main body of the Red Sea. However, a study by Ahmad et al. (1989) calculated the monthly variations in heat fluxes at the air-sea interface in coastal waters near Jeddah, Red Sea. The Red Sea possesses an irregular bottom topography. The coastline is bordered by shallow fringing reefs, the edges of which slope gently into lagoons bordered by an offshore barrier reef system (Morley 1975).

ANOVA showed no significant differences between treatments for 0

ANOVA showed no significant differences between treatments for 0.3 M NaCl intake [F(3, 12) = 3.0; P > 0.05] or water intake [F(3, 12) = 4.0; P > 0.05] in fluid replete rats or between treatments for 0.3 M NaCl intake [F(3, 15) = 0.9; P > 0.05] or water intake [F(3, 15) = 3.3; P > 0.05] in FURO + CAP-treated rats that

received injections in sites outside the LPBN. Misplaced injections were ventral (MPBN), dorsal or rostral to the LPBN. Some rats had unilateral KRX-0401 price injections partially into the LPBN. Similar to previous results (Callera et al., 2005 and De Oliveira et al., 2007), the present study shows that bilateral injections of muscimol (GABAA receptor agonist) into the LPBN induce hypertonic NaCl and water ingestion in fluid replete rats (untreated rats) and increase 0.3 M NaCl intake in FURO + CAP-treated rats. The involvement of GABAA receptors of the LPBN in the control

of water and NaCl intake is supported by a previous study showing that the GABAA receptor antagonist bicuculline injected into the LPBN completely blocked water and hypertonic NaCl intake induced by muscimol, which suggests that muscimol activates LPBN GABAA receptors to increase sodium intake (Callera et al., 2005). The present results extend the conclusions of the previous study by showing that pretreatment of the LPBN with bilateral injections of the nonpeptide AT1 receptor antagonist losartan reduce water and 0.3 M NaCl intake caused by muscimol injected into the same site

in fluid replete rats, as well as the MEK inhibitor increase in 0.3 M NaCl produced by muscimol injected bilaterally into the LPBN in FURO + CAP-treated rats. Injections of losartan alone into the LPBN did not change water or 0.3 M NaCl intake by untreated rats or FURO + CAP-treated rats. Results from rats with misplaced injections confirm that muscimol effects on water and 0.3 M NaCl intake are specific to the LPBN. The results also suggest that angiotensinergic mechanisms in the LPBN are essential for the dipsogenic and natriorexigenic responses induced by the blockade of LPBN neurons with muscimol in fluid replete rats or the increase in the natriorexigenic responses produced by muscimol injected into the LPBN in FURO + CAP-treated rats. Pretreatment with losartan into the LPBN reduced Phosphoprotein phosphatase muscimol effects on water and/or NaCl intake by fluid replete or FURO + CAP-treated rats. Therefore, if endogenous GABA release in the LPBN was important for FURO + CAP-induced water and sodium intake, similar effects would be expected when losartan alone was injected in FURO + CAP-treated rats. However, injections of losartan alone did not modify FURO + CAP-induced water or NaCl intake, suggesting that GABA release or its interaction with activated AT1 receptors in the LPBN is not essential for sodium or water intake induced by FURO + CAP.

In addition, the recognition of extensive LM positivity as a risk factor for residual/locally recurrent cancer would Epacadostat be helpful in selecting cases that may necessitate strict management such as immediate additional endoscopic treatment.

“Endoscopic submucosal dissection (ESD) is accepted as a treatment for gastric neoplasms. Several trials have shown the efficacy of gastric acid secretion inhibitors for post-ESD ulcers. However, to date there has been no consensus regarding the optimal drug regimens. Irsogladine has previously been shown to accelerate the healing of

gastric ulcers after Helicobacter pylori (H. pylori) eradication therapy. Hence, we conducted a randomized controlled trial to compare proton pump inhibitor (PPI) and combination PPI plus irsogladine treatments. To assess the efficacy find more of PPI and irsogladine combination therapy compared with PPI monotherapy for ESD-induced gastric ulcer healing. Ninety Six ESD-induced gastric ulcer patients

were enrolled in this study. In Group A(n=51), subjects received rabeprazole 10 mg/day and irsogladine 4 mg/day for 8 weeks and in Group B(n=45), subjects received rabeprazole 10 mg/day for 8 weeks. At 1, 4 and 8 weeks after ESD, we performed endoscopic examination to assess each gastric ulcer healing. There was no significant difference between group A and group B in the patient’s background. The ulcer healing rates at 4 weeks after ESD in group A were significantly higher than those in group B in the full analysis set (19.6% vs 5.13%; P < 0.05, chi-square test). The concomitant use of PPI and irsogladine was more effective than the PPI alone for treating for ulcers within 4 weeks after ESD. Therefore, the combination therapy of PPI and irsogladine was favorable regimen in patients with artificial ulcer after ESD. “
“Subepithelial tumors (SETs) can be challenging to diagnose and treat by endoscopy. Biopsies may not reach the tumor and endoscopic ultrasound (EUS)-guided tissue acquisition can be difficult due to small lesion size and mobility. Resection has been reported, but carries inherent risks of bleeding and perforation. Loop ligation can achieve ischemic tumor ablation, but may not capture broad-based lesions, and does not address tissue acquisition for diagnosis.

Gauch [10] and Gauch et al [12] reviewed the AMMI and GGE litera

Gauch [10] and Gauch et al. [12] reviewed the AMMI and GGE literature, favoring AMMI. Yan et al.

[11] responded to those articles, favoring GGE. Several studies have also been performed comparing GGE biplots and YSi in bean [13], maize [14], and durum wheat [15]; GGE biplots and JRA in maize [16] and triticale [17]; and JRA and AMMI models in cereal crops [18] for stability analysis. However, little is known about rank correlation selleck chemicals among the four statistical methods (AMMI analysis, GGE biplot, JRA, and YSi statistic) applied in a single study. The main objectives of the present study were to (i) compare the statistical methods (AMMI analysis, GGE biplot, JRA, and the YSi statistic) in the ranking of 20 winter wheat genotypes for yield, stability, and yield–stability

and (ii) evaluate rank correlations among the statistical methods on the basis of yield ranks, stability ranks, and yield–stability ranks. Grain yield data obtained from 20 winter wheat genotypes, consisting of 18 breeding lines Stem Cell Compound Library high throughput (G1–G18) and two check cultivars (G19 and G20, representing the landrace “Sardari” and the released cultivar “Azar-2”, respectively), grown in eight test locations representative of winter wheat growing areas in Iran for three consecutive cropping seasons (2003–2005), were subjected to analysis of rank correlation among the four statistical procedures (AMMI, GGE biplot, JRA, and YSi statistic) in the rankings of genotypes. In each environment (location–year combination), the

experimental layout was a randomized complete block design with four replicates. The plot size was 7.2 m2 (6 rows, 6 m long, 20 cm row spacing). The fertilizer rate was 50 kg N ha− 1 and 50 kg P2O5 ha− 1 applied at planting stage. Combined analysis of variance (ANOVA) for grain yield data was performed to determine the effects of environment, genotype, and GE interaction. Four statistical methods were applied to evaluate GE interaction in the wheat MET data. Regression analysis was performed for each of the 20 wheat genotypes based on the method of Eberhart and Russell [5]. The performance of each genotype in each environment was regressed on the means of all genotypes in each environment. Genotypes with regression coefficient (b) of unity and variance of regression Protein kinase N1 deviations (S2di) equal to zero will be highly stable. The yield stability (YSi) statistic was generated as described by Kang [19] and applied for selecting high-yielding and stable genotypes. Ranks were assigned for mean yield, with the genotype with the highest yield given a rank of 20. Similarly, ranks were assigned for the stability parameter with the lowest estimated value receiving the rank of 1. Stability ratings were computed as follows: − 8, − 4, and − 2 for stability measures significant at P < 0.01, 0.05, and 0.10, respectively; and 0 for the non-significant stability measure.

Participants who

Participants who

selleck products were 5 years of age or older at the time of sampling were asked to provide blood at recruitment and after each peak in confirmed case detection for paired serology. Age- and sex-standardized estimates of the risk of influenza infection and illness per season in persons 5 years of age or older were reported previously.21 Three influenza seasons were identified in this study period (Table 1). The number of people that provided blood samples spanning each season, the numbers infected as determined by serology and RT-PCR, and their age distribution is shown as supplementary information (Fig. S1). Males, and participants aged less than 5 or in their late teens were under-represented in the group that could be analyzed (Fig. S1). Genetic and antigenic characterization of the viruses isolated and used for serology is shown in supplementary information (Fig. S2 and Table S1). The H1N1 viruses isolated in season one (S1) in 2008 were A/Brisbane/59/2007-like, and B

virus isolates were of the B-Yamagata-lineage and were B/Florida/4/2006-like, representing strains that were antigenically distinct from the pre-study season. The H3N2 viruses isolated in S1 were antigenically A/Brisbane/10/2007-like, as in the pre-study season, and caused few infections. The H3N2 viruses isolated in the second season (S2) in Spring 2009 were antigenically distinct A/Perth/16/2009-like strains, and caused the highest incidence of infection, whereas two

H1N1 isolates were similar to the S1 isolate. HI titers with WHO reference sera against seasonal H1N1 XL184 molecular weight were 1280 against the 2008 H1N1 isolate and 640 against both 2009 H1N1 isolates. The only B virus isolated in 2009 belonged to the B-Victoria lineage, L-gulonolactone oxidase and the National Influenza surveillance system identified a shift in B-lineage predominance from Yamagata to Victoria in 2009. However serology was only performed with a Yamagata lineage virus. The third season (S3) in Autumn 2009, was caused by the pandemic H1N1 2009 strain (A/California/04/2009), which resulted in a high incidence of infection compared to individual seasonal strains. It was not feasible to collect swabs from all cohort participants weekly; hence infections were also identified by HI antibody seroconversion. As in our previous report, seroconversion was defined as at least a 4-fold rise in titer with a post-season titer of at least 40.21 We have recently reported that the pattern of 2-fold increases in HI titer cannot be fully explained by assay variability, and that a reliance on four-fold titer increases to define infection may under estimate the true incidence of infection.24 However, since it is not possible to adjust for assay variability in an individual level analysis we did not apply a 2-fold definition.

4 mL of an iodine solution containing 3% (w/v) KI, 0 3% (w/v) I2

4 mL of an iodine solution containing 3% (w/v) KI, 0.3% (w/v) I2 diluted to 4% (v/v) and its optical density was read at 620 nm using a spectrophotometer (Secoman). A standard curve for optical density as a function of starch concentration

was used to determine starch concentration. One unit of α-amylase activity PARP inhibitor (U) was defined as the amount of enzyme able to hydrolyze 1 g of soluble starch in 60 min under the experimental conditions. All the values presented are means of three replicates. The optimization of α-amylase in mixed culture was focused on three important independent variables, the initial yeast to bacteria ratio (R0), the temperature (T) and the pH. A Box–Behnken design with five replicates at the central point resulting in 17 experiments generated by Design Expert 8.0 software was used [5]. Each independent variable was studied at three different levels (low, medium, and high, coded as −1, 0, and +1, respectively). The coded variables are shown in Table 1 and the experimental design is shown in Table 2. All the experiments were done in triplicate and the average

of α-amylase ABT-199 nmr production obtained was taken as the dependent variable or response (Yi). The second order polynomial coefficients were calculated and analyzed using the Design Expert 8.0 software. The general form of the second order polynomial equation is: equation(4) Yi=α0+∑αiXi+∑αiiXi2+∑αiiXiXjWhere Yi is the predicted response, XiXj are input variables which influence the response variable Y; α0 is the offset term; αi is the ith linear coefficient; αii the ith quadratic coefficient and αij is the ijth interaction coefficient. In order to confirm effective interaction between studied microbial strains, the ANOVA of growth parameters μmax and Nmax when passing from pure to mixed culture was performed. This analysis included the Fisher’s F-test and its associated probability p(F). All these statistical analyses were carried out using a computer’s program Design Expert 8.0. The microbial strains propagated in culture broth according to a usual profile including lag, exponential and stationary phases. The maximum specific growth rate (μmax) and lag

time of each strain in starch broth at 30 °C in mono and mixed cultures were derived by the curve fitting procedure Carnitine palmitoyltransferase II of Baranyi and Robert [3]. The values of μmax and lag time were 0.142 h−1; 3.302 h, 0.163 h−1; 5.574 h, 0.105 h−1; 6.445 h (average of three replications) respectively for B. amyloliquefaciens 04BBA5, L. fermentum 04BBA19 and S. cerevisiae. These kinetics parameters, their standard deviations and the ANOVA are summarized in Table 3 and Table 4. The first mixed culture (mixed culture I) involved B. amyloliquefaciens 04BBA15 and S. cerevisiae. The comparison of the profile of growth for pure and mixed cultures ( Fig. 1a and b) showed that when B. amyloliquefaciens 04BBA15 was growing together with S. cerevisiae, the growth curve of S.
