this study aims to determine the effect of fermentation condition and saccharomyces strains on the ph, foam property and co2 concentration of non-alcoholic beer (ma-al-shaeer). for this, the beer samples were inoculated with four different species of saccharomyces (saccharomyces rouxii 70531, s. rouxii 70535, s. ludwigii 3447 and s. cerevisiae 70424) and fermented for 48h in both aerobic and pe...

Enantioselective production of (S)-2-phenyl-1-propanol is important as in order to be applied industry, a high degree optical purity required. Besides organocatalysts and metal complexes, biocatalysts can used for its synthesis their isolated form or whole-cell biocatalysts, both which have various advantages disadvantages. In this research, Saccharomyces cerevisiae, biocatalyst, recombinant ho...

Saccharomyces cerevisiae cannot produce extracellular lipase and utilize low-cost lipid substrates. This study aimed to express extracellular lipase from Yarrowia lipolytica in S. cerevisiae, construct recombinant oily substrate consumer strains, and compare the roles of native and mutant Y. lipolytica extracellular lipases in S. cerevisiae. The LIP2 gene of Y. lipolytica DSM3286 and its mutant...

The present study analyzes the lack of culturability of different non-Saccharomyces strains due to interaction with Saccharomyces cerevisiae during alcoholic fermentation. Interaction was followed in mixed fermentations with 1:1 inoculation of S. cerevisiae and ten non-Saccharomyces strains. Starmerella bacillaris, and Torulaspora delbrueckii indicated longer coexistence in mixed fermentations ...

the aim of present study is investigating effect of treated lemon pulp by saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. in this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by saccharomyces cerevisiae yeast on protein recei...

Background Saccharomyces cerevisiae wild strains generally have poor xylose-utilization capability, which is a major barrier for efficient bioconversion of lignocellulosic biomass. Laboratory adaption is commonly used to enhance xylose utilization of recombinant S. cerevisiae. Apparently, yeast cells could remodel the metabolic network for xylose metabolism. However, it still remains unclear wh...

We recently demonstrated that Saccharomyces cerevisiae protoplasts can take up bovine papillomavirus type 1 (BPV1) virions and that viral episomal DNA is replicated after uptake. Here we demonstrate that BPV virus-like particles are assembled in infected S. cerevisiae cultures from newly synthesized capsid proteins and also package newly synthesized DNA, including full-length and truncated vira...

BACKGROUND While Saccharomyces cerevisiae is a promising host for cost-effective biorefinary processes due to its tolerance to various stresses during fermentation, the metabolically engineered S. cerevisiae strains exhibited rather limited production of higher alcohols than that of Escherichia coli. Since the structure of the central metabolism of S. cerevisiae is distinct from that of E. coli...

This study examines the fermentation of autohydrolyzed and 1-n-butyl-3methylimidazolium acetate (C4mimOAc) pretreated sugarcane bagasse, using four different yeast strains to determine the efficiency of bioethanol production. Three strains of Saccharomyces cerevisiae (S. cerevisiae) and one of Scheffersomyces stipitis (S. stipitis) were employed in this study. It was observed that the sugarcane...

Saccharomyces cerevisiae protoplasts exposed to bovine papillomavirus type 1 (BPV-1) virions demonstrated uptake of virions on electron microscopy. S. cerevisiae cells looked larger after exposure to BPV-1 virions, and cell wall regeneration was delayed. Southern blot hybridization of Hirt DNA from cells exposed to BPV-1 virions demonstrated BPV-1 DNA, which could be detected over 80 days of cu...
