Screening of fungi efficient in feather degradation and keratinase production
Two hundred thirty four fungal strains were isolated by baiting method, for their feather degradation and keratinase producing ability. Fungi were tested on solid milk agar plates and in submerged culture. Maximum clearing zone was made by Chrysosporium indicum (7mm) on solid agar plates. The highest keratinase production was found in case of Acremonium strictum (74.40Unit/mL & 124.72 Unit/ml i...
متن کاملIndustrial application of keratinase and soluble proteins from feather keratins.
Feather keratin is highly resistant to degradation, but some keratinase producing microorganisms can easily degrade these insoluble keratins. These keratinase producing species have an important application in removal of poultry waste and recycled into valuable byproduct. Bacillus sp was screened from soil samples of slaughterhouse and poultry farm area using azokeratin medium. Highest keratina...
متن کاملEfficient Degradation of Feather by Keratinase Producing Bacillus sp.
Keratinase producing microorganisms are being increasingly utilized for degradation and recycling of poultry feather waste. Two native strains BF11 (Bacillus subtilis) and BF21 (Bacillus cereus) degrading keratin completely were characterized. The native strains produced more than 10 KU/mL of enzyme. Strain improvement resulted in isolation of MBF11 and MBF21 from BF11 and BF21 isolates, respec...
متن کاملFirm but slippery attachment of Deinococcus geothermalis.
Bacterial biofilms impair the operation of many industrial processes. Deinococcus geothermalis is efficient primary biofilm former in paper machine water, functioning as an adhesion platform for secondary biofilm bacteria. It produces thick biofilms on various abiotic surfaces, but the mechanism of attachment is not known. High-resolution field-emission scanning electron microscopy and atomic f...
متن کاملOptimization of Culture Conditions for Keratinase Production in Streptomyces Sp. JRS19 for Chick Feather Wastes Degradation
The aim of this study was to find the optimal conditions of a newly isolated Streptomyces strain JRS 19. Screening for keratinase producing bacteria and their keratinase production were investigated. The keratinase produced by the isolate was purified by chromatographic techniques and the optimum pH maintained was 7.0 and maintained at different temperatures Viz., 20ºC, 25ºC, 30ºC, 35ºC and 40º...
