The consumer demand is increasing for composite flour based bakery products like biscuits.The incorporation of buckwheat can be justified in composite flour based biscuits as it has beneficial nutraceutical properties and its gluten-free nature can play important role in preventing celiac problem. The physicochemical and functional properties of buckwheat flour were studied and biscuits were pr...

During the screening of Actinomycetes for novel bio-active components, we found that the terrestrial Streptomyces sp. isolate GW71/2497 produced large quantities of chartreusin, which precipitated during the concentration of the extract and was responsible for the high activity against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, and Streptomyces viridochromogenes (Tü 57). On a s...

A soybean flour-induced, soluble cytochrome P-450 (P-450soy) was purified 130-fold to homogeneity from Streptomyces griseus. Native cytochrome P-450soy is a single polypeptide, with a molecular weight of 47,500, in association with one ferriprotoporphyrin IX prosthetic group. Oxidized P-450soy exhibited visible absorption maxima at 394, 514, and 646 nm, characteristic of a high-spin cytochrome ...

Bacillus amyloliquefaciens DS11 phytase (DS11 phytase) and Aspergillus ficuum phytase (AF phytase) activities were investigated by measuring the release of phosphate from phytate in animal feedstuff such as wheat bran, corn meal, soybean meal and rice flour at pH 5 and 7. In all the tested feedstuff, the enzymatic activity of DS11 phytase was more active at pH 7, but that of AF phytase was more...
