Enhanced Production of Alkaline Protease by Bacillus Subtilis in Submerged Fermentation
An alkaline protease producing strain was isolated from the sample collected from a slaughter house in Krishnagiri (District), T.N., India identified as Bacillus subtilis. Optimization of process parameters, surfactants as stimulants and strain improvement by UV for increased production of protease was carried out. Further the enzyme was partially purified and characterized. The most important ...
متن کاملScreening and Optimization of Cultural Parameters for an Alkaline Protease Production by Aspergillus Terreus Gr. under Submerged Fermentation
An alkaline protease-producing fungus was screened from potato grown soil fields of Bangalore and identified as Aspergillus terreus gr. based on morphological and microscopic features. The selected growth medium contained casein (1%) as a sole source of carbon and nitrogen. The pH of the medium was adjusted to 10.0 using sodium carbonate in order to isolate alkalophilic fungi. The best process ...
متن کاملXylanase Production by a Thermo-tolerant Bacillus Species under Solid-state and Submerged Fermentation
Effects of xylose on xylanase production by a thermophilic Bacillus sp showed diverse patterns on corn cob (CC) and wheat bran (WB) as sole carbon sources in solidstate fermentation (SSF) and submerged fermentation (SmF). Supplementation of these media with either mineral salt solution (MSS) or yeast extract peptone (YEP) also exerted variable effects. While under SSF, xylose stimulated xylanas...
متن کاملKeratinolytic Potential of Feather-Degrading Bacillus polymyxa and Bacillus cereus
Keratinolytic abilities of Bacillus polymyxa B20 and B. cereus B5esz were evaluated in liquid cultures in mineral media containing chicken feathers. Both tested strains were capable of effective liquefying and biodegradation of feather keratin, up to 56.5 – 72.1% in ten-day cultures, releasing considerable amounts of hydrolysis products. Tested bacteria were mesophilic species, producing highes...
متن کاملProduction and Characterization of Keratinolytic Protease of Bacillus licheniformis MZK-03 Grown on Feather Mill
Proteases are catabolic enzymes that catalyze the complete hydrolysis of protein. They constitute one of the most important groups of industrial enzymes, accounting for nearly 60% of the total worldwide enzyme sale1. Keratinolytic protease is a specific protease that has immense commercial importance. It acts on keratin of the hides thus can be used in dehairing2. This enzyme along with proteas...
