خمیرترش، یک قطعه خمیر از پخت قبلی میباشد که برای تولید نان با آرد، نمک و آب مخلوط و سپس ذخیره میشود. میکروارگانیسمهای اصلی خمیرترش، باکتریهای اسید لاکتیک و مخمرها هستند که نقش مهمی در بهبود طعم، بافت و ماندگاری فراوردههای نانوایی ایفا میکنند. در تحقیق حاضر، 7 نمونه خمیرترش از ییلاقهای ماسوله، همدان، نطنز، کیاسر، آمل، فومن جمعآوری و جهت انجام تحقیق استفاده گردید. باکتریهای اسید لاکتیک و...
this experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...
Vitamin D deficiency causes osteoporosis, osteopenia, fractures, rickets and more recently is linked with some chronic illnesses such as cancer. Because of the safety and probiotic properties of the yeast Saccharomyces cerevisiae, we hypothesized that yeast cells enriched with cholecalciferol (vitamin D3) could represent a solution for prevention or treatment of vitamin D deficiency. In this st...
in view of the increase in saccharomyces cerevisiae mannan content, the culture condition for s.cerevisiae were optimized in this study. the influence of culture condition such as original ph, inoculum size, and temperature on mannan production were evaluated using response surface methodology. the mathematical model was established by the quadratic rotary combination design. with the order of ...
Background and Aim: Pseudomonas aeruginosa is an important ubiquitous and especially common pathogen in the hospital. Exotoxin A that encoded by exoA gene has a role in pathogenesis of this bacterium. Today, probiotics are widely used in the treatment and prevention of diseases. The present study aimed to study the Saccharomyces cerevisiae S3 effect on the expression of exoA gene. Materials an...
Background and Objective: According to definition of probiotics by WHO/FAO that is “Live microorganisms which, when present in sufficient amount, confer beneficial effects to the host”. Saccharomyces cerevisiae is the first non-pathogenic yeast which is known as a probiotic for humans that its helpful effects for humankind has been proved. Pseudomonas aeruginosa is one of the most ...
several strains of saccharomyces cerevisiae were isolated from different sources. these strains were under taken for ethanol tolerance analysis and growth under stress condition. exponential phase to various concentrations of ethanol (2–26% v/v) for 1 h was used for isolation of resistant strains. viable cells were isolated and purified by inoculation of diluted samples on yeast extract peptone...
background: glutathione (gsh) is a non-protein thiol compound, which plays an important role in the response to oxidative stress and nutritional stress. the aim of this study was to isolate indigenous s. cerevisiae strains capable of effectively produce gsh. methods: one hundred-twenty sweet fruit samples were collected. the strains were isolated on yeast glucose chloramphenicol (ygc) agar medi...
the hepatitis b surface antigen ( hbsag) gene was isolated from an iranian hbeag positive carrier by pcr. the gene was cloned in puc19 for sequencing and pyes2 for expression in saccharomyces cerevisiae, which pnf1 and pdf3 constructs were made respectively. the sequencing data showed that the isolated hbsag gene shared more than 90% homology with the ayw subtype. the pdf3 was transferred into ...
The aim of this study was to investigate the effects of saccharomyces cerevisiae yeast and butyrate monoglycerides on the performance, blood parameters and nutrients digestibility in suckling Holstein calves. For this experiment, 32 newly-born Holstein calves (average age 1-8 days; average weight 38±1 kg) were used in a completely randomized design with 2×2 factorial arrangement, 4 treatmen...
