Protein recovery under sonication treatment and autolysis, also protein hydrolysis progress during enzymatic hydrolysis (using trypsin and chymotrypsin) and autolysis (using endogenous enzymes) were investigated in Saccharomyces cerevisiae and Kluyveromyces marxianus. Crude protein content of dried yeast cells were 53.22% and 45.6% for S.cerevisiae and K.marxianus, respectively. After 96 hrs of...

Berberine was loaded in yeast cells of Saccharomyces cerevisiaeas a novel pharmaceutical carrier to improve the treatment ofmany diseases. The yeast-encapsulated active materialsshowedhigh stability and bioavailability due to the enhanced solubility and sustained releasing. In this study, different characteristics of prepared berberine loaded yeast cells (loading capacity, release kinetic order...

Background Previous reports showed that immobilization stress (IMS) results in severe damages at spermatogenesis level. Present study was performed in order to evaluate the protective effect of selenium-enriched yeast fragments on IMS-induced derangements. MaterialsAndMethods For this purpose, 42 mature male Wister rats were assigned into 6 groups (7 rats in each group) including; control, stre...

In this work was evaluated the effect of sequential inoculum Hanseniaspora uvarum AS27 strain and a commercial Saccharomyces cerevisiae yeast on physical–chemical organoleptic features Aglianico, traditional red wine Southern Italy. Four fermentation treatments pilot scale were performed. treatment A, alcoholic spontaneously conducted by indigenous yeasts present in grape must. B C inoculated r...

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...

There is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. We aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. Sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

Abstract The benefit of bioaugmentation activated sludge (AS) with yeasts was tested using AS and wastewaters (WW) that originated from the chemical industry, as well synthetic WW. A stimulating effect Saccharomyces cerevisiae on microbial respiration intensity in shown. added yeast biomass maintained viability AS, an inhibitory BAC Bacilli found; however, addition to reduced this effect.

In wine fermentation, improved complexity and sensorial properties can arise from the use of non-Saccharomyces yeast. Generally less alcohol tolerant, such strains often do not finish therefore requiring a second inoculation with more robust Saccharomyces cerevisiae, usually added on Day 3. This sequential approach affords time to make an impact before being overtaken by S. cerevisiae. However,...

Two related killer strains of Saccharomyces cerevisiae were mutagenized and screened for nonkiller variants. About 20% of the mutants derived from one strain lacked all detectable double-straned ribonucleic acid (dsRNA). About 70% of the mutants from the other strain lacked one of the dsRNA species normally associated with the killer factor and had in its place another species of dsRNA with a l...

The function of a protein generally is determined by its three-dimensional (3D) structure. Thus, it would be useful to know the 3D structure of the thousands of protein sequences that are emerging from the many genome projects. To this end, fold assignment, comparative protein structure modeling, and model evaluation were automated completely. As an illustration, the method was applied to the p...
