In the present study, out of 22 Streptomyces strains, Streptomyces parvulus VCCM 22513 produced the highest chitinase activity. Time courses of incubation revealed that the maximum chitinase (0.91 ± 0.04 U/mL) of this strain was observed after 96 hours in the yeast extract salts medium supplemented with 10.0 g/L colloidal chitin.

The effect of different nitrogen sources on cell growth and polyhydroxyalkanoate (PHA) accumulation by halophilic bacterium strain Yangia sp. ND199 was investigated. The combination of 0.5 g/L potassium nitrate (KNO3) and 0.5 g/L yeast extract was shown to be good nitrogen source for cell growth and PHBV production by Yangia sp. ND199.

Deproteinated cheese whey was used for biomass production of probiotic strain Lactobacillus helveticus MTCC 5463 in a biofermenter. Optimization of growth parameters such as temperature, pH and time of incubation as well as nutrient supplementation of cheese whey was carried out using response surface methodology (RSM). Cheese whey supplemented with 0.95% yeast extract and 0.95% proteose peptone, inoculated with 6% (v/v) active culture of L. helveticus MTCC 5463 and fermented for 24 h at optimized temperature of 40ºC and pH 6.25 yielded 3.25 g/L dry cell biomass and 14.

Mitochondrial ribosomal proteins (mrps) of the budding yeast, Saccharomyces cerevisiae, have been extensively characterized genetically and biochemically. However, the list of thegenes encoding individualmrps is still not complete and quite a fewof the mrps are only predicted from their similarity to bacterial ribosomal proteins. We have con-structed a yeast strain in which one of the small subunit proteins, termed Mrp4, was tagged with S-peptide and used for affinity purification of mitochondrial ribosome. ...

In eukaryotes, pre-rRNA processing depends on a large number of non-ribosomal trans-acting factors that form large and intriguingly organized complexes. A novel nucleolar protein, Nop53p, was isolated by using Nop17p as bait in the yeast two-hybrid system. Nop53p also interacts with a second nucleolar protein, Nip7p. A carbon source-conditional strain with the NOP53coding sequence under the control of theGAL1promoter did not grow in glucose-containing medium, showing the phenotype of an essential gene. ...

The addition of glucose toSaccharomyces cerevisiaecells causes reprogramming of gene expression. Glucose is sensed bymembrane receptorsaswell as (so far elusive) intracellular sensing mechanisms. The availability of four yeast strains that display different hexose uptake capacities allowed us to study glucose-induced effects at different glycolytic rates. Rapid glucose responses were observed in all strains able to take up glucose, consistent with intracellular sensing.

During a search for cDNAs encoding plant sterol acyl-transferases, we isolated four full-length cDNAs fromAra-bidopsis thaliana that encode proteins with substantial identity with animal lecithin : cholesterol acyltransferases (LCATs). The expressionof one of these cDNAs,AtLCAT3 (At3g03310), invarious yeast strains resulted in the doubling of the triacylglycerol content.

A fatty-acid-metabolizing enzyme fromArabidopsis thaliana, CYP94C1, belonging to the cytochrome P450 family was cloned and characterized. CYP94C1 was heterologously expressed in aSaccharomyces cerevisiae strain (WAT11) engineered for P450 expression. When recombinant yeast microsomes were incubated with lauric acid (C12:0) for 15 min, one major metabolite was formed.

The assembly status of the cytochromebc1 complex has been analyzed in distinct yeast deletion strains in which genes for one or more of thebc1 subunits were deleted. In all the yeast strains tested, a bc1 sub-complex of approximately 500 kDa was found when the mitochondrial membranes were analyzed by blue native electrophoresis.

Studies of mammalian prion diseases such as bovine spongiform encephalopathy have suggested that different strains consist of prion proteins with different conformations. Two recent studies of yeast prions have now formally demonstrated that multiple stable protein conformations are the basis of strain variation. deposited research Transmissible spongiform encephalopathies (TSEs) are a group of closely related neurodegenerative conditions of animals

Problem statement: Dilute sulphuric acid and enzymatic hydrolysis methods were used for sugar extraction. Xylose and glucose sugars were obtained from corn cobs. Approach: Acid hydrolysis of corn cobs gave higher amount of sugars than enzymatic hydrolysis. Results: The results showed that optimal temperature and time for sugar fermentation were approximately 25°C and 50 h by two yeast strains (S. cerevisiae and P. Stipitis) respectively.
