Ribosome synthesis is an essential process in all cells. In Sacharomyces cerevisiae, the precursor rRNA, 35S pre-rRNA, is folded and assembled into a 90S pre-ribosomal complex. The 40S ribosomal subunit is processed from the pre-ribosomal complex. This requires concerted action of small nucleolar RNAs, such as U3 snoRNA, and a large number of trans-acting factors. Mrd1p, one of the essential sm...

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...

This study analysed the contribution of each omega-3 desaturase to the cold response in soybean. Exposure to cold temperatures (5 °C) did not result in great modifications of the linolenic acid content in leaf membrane lipids. However, an increase in the GmFAD3A transcripts was observed both in plant leaves and soybean cells whereas no changes in GmFAD3B or GmFAD3C expression levels were detect...

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...
