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 ...

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...

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...

The Biosorption property of S. cerevisiae for chromium uptake was investigated in an immobilized cell bioreactor. Saw dust was utilized as the solid bed in the reactor. Adsorption of S. cerevisiae on saw dust obeys a first order reaction kinetic up to 6 hours. The immobilized biomass particles are porous and exist in the new generation of biological adsorbent. Chromium biosorption was studied i...

Background and Objective: Saccharomyces cerevisiae is one of the probiotic yeasts that has positive effects on health. Pseudomonas aeruginosa is one of the important opportunistic pathogenic bacteria. The purpose of this study was to determine the effect of supernatant of Saccharomyces cerevisiae on preventing the growth of Pseudomonas aeruginosa and its effect on exotoxin S gene expression by ...

BACKGROUNDS: Optimization of microbial compositions and load in live food during the process of bioencapsulation is one of the most important concerns in aquaculture, as it can promote the growth and feeding parameters of fish larvae. OBJECTIVES: The aim of this study was to determine the growth and feeding performance of Persian sturgeon larvae fed with bioencapsulated D. magna with Saccharomy...

سبوس گندم با دارا بودن فیبر و املاح بالا از خواص تغذیه‌ای سودمندی برخوردار است، اما به‌دلیل حضور ترکیب ضد تغذیه‌ای به‌نام اسید فیتیک کاربرد محدودی دارد. در این پژوهش اثر سه آغازگر مختلف تهیه شده از S. cerevisiae PTCC 5052  و L. Plantarum PTCC 1058، درجه حرارت (25، 30 و 35 درجه سانتی‌گراد) و طول زمان تخمیر (0،2، 4، 6 و 8 ساعت) بر مقدار pH ، اسیدیته و غلظت اسید فیتیک سبوس گندم استریل شده بررسی گر...
