Yeasts, especially Saccharomyces cerevisiae, are one of the oldest organisms with broad spectrum of applications, owing to their unique genetics and physiology. Yeast extract, i.e. the product of yeast cells, is extensively used as nutritional resource in bacterial culture media. The aim of this study was to develop a simple, rapid and cost benefit process to produce the yeast extract. In this ...

Charcoal-yeast extract agar is a new bacteriological medium that supports excellent growth of the Legionella pneumophila. It results from modifications made in an existing L. pneumophila medium, F-G agar. Yeast extract, instead of an acid hydrolysate of casein, serves as the protein source. Beef extractives and starch are not added. Activated charcoal (Norit A or Norit SG) is included at 0.20% ...

OBJECTIVES Ganoderma lucidum (GL) is one of the most commonly used Chinese herbs in the oriental community, with more than 30% of pediatric cancer patients taking GL. The immunomodulating and anticancer effects exerted by GL extracts have been demonstrated by in vitro and in vivo studies. There was, however, no comparison between the immunomodulating effects of GL mycelium extract (GL-M) and sp...

Dried carpophores of Ganoderma lucidum were exposed to the hot water extraction and alcohol precipitation to obtain polysaccharides, which were than refined by the dialyses. Dry polysaccharide extract (GL-I) was partially purified and used for the investigation of antioxidant properties. The antioxidant activity was determined by the conjugated diene method, ascorbic acid and α-tocopherol were ...

A newly isolated thermotolerant ethanologenic yeast strain, Issatchenkia orientalis IPE 100, was able to produce ethanol with a theoretical yield of 85% per g of glucose at 42°C. Ethanol production was inhibited by furfural, hydroxymethylfurfural and vanillin concentrations above 5.56 gL(-1), 7.81 gL(-1), and 3.17 gL(-1), respectively, but the strain was able to produce ethanol from enzymatical...

Dietary fibers (DF) may affect energy balance, an effect often ascribed to the viscous nature of some water soluble DF, which affect luminal viscosity and thus multiple physiological processes. We have tested the hypothesis that viscous linseed DF reduce apparent nutrient digestibility, and limit weight gain, in a randomized feeding trial where 60 male, growing, Wistar rats, with an initial wei...

Recent studies have revealed that cell cycle control in Gl or G2 phase is the basis for understanding the mechanism for tumorigenesis1'2*. It is therefore likely that inhibitors of Gl and/or G2 progression are candidates for a new type of chemotherapeutic agents. Since the cell cycle regulators such as cyclins and CDKs are highly conserved from yeast to humans, screening for inhibitors of the y...
