This study investigated the optimal yeast strains for producing single cell protein based on waste sugar beet pulp (SBP) under various biomass loads. All tested were capable of growing biomass. Candida utilis and Saccharomyces cerevisiae Ethanol Red produced greatest increase in fresh SBP (ΔN 1.84%). Scheffersomyces stipitis 2.27%) provided highest dried SBP. showed significant assimilation nit...

A new biosorbent, methylated yeast (MeYE), was prepared for the adsorptive separation of proteins from aqueous solutions. Yeast was methylated in a 0.1 M HCl methyl alcohol solution at room temperature. About 80% of the carboxylic groups of yeast could be methylated within 9 h. The adsorption of egg albumin onto MeYE was studied to evaluate the protein adsorption ability of MeYE. At near neutra...

Abstract The effects of wheat gluten hydrolysates (WGH) and their ethanol elution fractions obtained on XAD-16 resin physiological activity fermentation performance brewer’s yeast during very-high-gravity (VHG) worts were investigated. results showed that the addition WGH in VHG significantly enhanced biomass viability, further increased fermentability, yield productivity yeast. Supplementation...

Suitable mixtures of glucose and furfural may provide novel strategies for C-C bond formation on due to the versatility low-cost biological catalysts. We use in-cell NMR with non-engineered commercial yeast as catalyst determine interplay between metabolism in yeast. The presence is shown modulate kinetic barriers conversion favor accumulation acetaldehyde situ. As a result, carbons are remarka...

The aim of this study was dual. Firstly, the exploitation of a completely new and alternative source for yeast β-glucan industrial production, yeast wastes biomass. Secondly, the utilization of winery yeast wastes for the production of added value products as a part of an intergraded and environmental friendly wine industry. β-Glucan isolation from red wine lees was performed in a two step proc...

β-D-glucan is a D-glucose biopolymer. The cell wall of yeast contains β-Dglucans. βGlucan has been isolated from barley, oat, mushrooms, algae bacteria and yeasts. Spent brewer’s yeast has been widely used for β-glucan production but yeast waste biomass from wine industry has not been yet utilized. Yeast β-glucan can be incorporated in various functional food, beverage and pharmaceutical produc...

BACKGROUND Oleaginous microorganisms are attractive feedstock for production of liquid biofuels. Direct hydrothermal liquefaction (HTL) is an efficient route that converts whole, wet biomass into an energy-dense liquid fuel precursor, called 'biocrude'. HTL represents a promising alternative to conventional lipid extraction methods as it does not require a dry feedstock or additional steps for ...

Neolentinus kauffmanii (A.H. Smith) were found growing on decaying logs of wood in their large numbers within the kothaiyar forest area of Kanyakumari district, Tamilnadu, India. The present study was aimed to investigate the effect of different semi-synthetic growth media, pH, temperature, carbon, nitrogen and amino acids on vegetative growth of N. kauffmanii. The best mycelial extensions were...

BACKGROUND Oligocelluloses and oligoxyloses are partially hydrolyzed products from lignocellulosic biomass hydrolysis. Biomass hydrolysates usually contain monosaccharides as well as various amounts of oligosaccharides. To utilize biomass hydrolysates more efficiently, it is important to identify microorganisms capable of converting biomass-derived oligosaccharides into biofuels or biochemicals...

BACKGROUND Under N-limiting conditions, Saccharomyces cerevisiae strains display a substantial variability in their biomass yield from consumed nitrogen -in particular wine yeasts exhibit high growth abilities- that is correlated with their capacity to complete alcoholic fermentation, a trait of interest for fermented beverages industries. The aim of the present work was to assess the contribut...
