A novel strain of Bacillus sphaericus JS1 producing thermostable alkaline carboxymethyl cellulase (CMCase; endo-1,4-β-glucanase, E.C. was isolated from soil using Horikoshi medium at pH 9.5. CMCase was purified 192-fold by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography, with an overall recovery of 23%. The CMCase is a(More)
Ionically bound peroxidases (POD) were salt extracted from the pulp of four Indian apple varieties, i.e., Golden delicious HP, Golden delicious JK, Red delicious, and Royal delicious. They were precipitated with chilled ethanol. Thermal treatments of partially purified enzymes were given from 40-70 degrees C for 30 minutes. Golden delicious HP peroxidase(More)
Bacterial and archaeal diversity in geothermal spring water were investigated using 16S rRNA gene amplicon metagenomic sequencing. This revealed the dominance of Firmicutes, Aquificae, and the Deinococcus-Thermus group in this thermophilic environment. A number of sequences remained taxonomically unresolved, indicating the presence of potentially novel(More)
A strain of Bacillus coagulans RCS3 isolated from a hot-water spring produced significant beta-galactosidase activity at 10 days of growth in a flask. While enzyme production was maximum at 50 degrees C, the highest activity was at 65 degrees C, where the half-life was 2 h. A 2 degrees C decrease in temperature increased the half-life to 15 h without(More)
According to the National Family Health Survey, asthma is one of the leading diseases in India. In order to understand the complexity of asthma, the susceptibility genes need to be targeted for their association. Glutathione S-transferases play a major role in the detoxification of metabolites of oxidative stress resulting in inflammation and asthma. In the(More)
Microorganisms constitute two third of the Earth's biological diversity. As many as 99% of the microorganisms present in certain environments cannot be cultured by standard techniques. Culture-independent methods are required to understand the genetic diversity, population structure and ecological roles of the majority of organisms. Metagenomics is the(More)
BACKGROUND Asthma is the most prevalent disease in India according to the national survey conducted by NFHS 2 in 1998-399. Prostaglandin D2 (PGD2) is a bronchoconstriction inducing metabolite of arachidonic acid in the mast cells, which is produced on exposure to allergens and acts as a ligand for the Prostaglandin D2 Receptor (PTGDR). Polymorphisms in the(More)
Bacillus coagulans RCS3 isolated from hot water springs secreted five isozymes i.e. β-gal I-V of β-galactosidase. β-gal III isozyme was purified using DEAE cellulose and Sephadex G 100 column chromatography. Its molecular weight characterization showed a single band at 315kD in Native PAGE, while two subunits of 50.1 and 53.7 kD in SDS PAGE. β-Gal III had(More)
BACKGROUND The most recurrent and considered second most frequent cause of cancer-related deaths worldwide in women is the breast cancer. The key to diagnosis is early prediction and a curable stage but still treatment remains a great clinical challenge. Origin of the Problem: A number of studies have been carried out for the treatment of breast cancer(More)
