Production and Characterization of Keratinolytic Protease from New Wool-Degrading Bacillus Species Isolated from Egyptian Ecosystem
Novel keratin-degrading bacteria were isolated from sand soil samples collected from Minia Governorate, Egypt. In this study, the isolates were identified as Bacillus amyloliquefaciens MA20 and Bacillus subtilis MA21 based on morphological and biochemical characteristics as well as 16S rRNA gene sequencing. B. amyloliquefaciens MA20 and B. subtilis MA21 produced alkaline keratinolytic serine pr...
متن کاملCharacterization of the keratinolytic activity of indigenous Bacillus subtilis keratinase
Keratins are water insoluble proteins of our environment. Being extremely resistant to degradation by proteolytic enzymes, keratins are digested mainly by alkali and keratinase enzymes. The aim of present study was to characterize the indigenous keratinase for potentials of keratin-degrading activities. We report the purification and characterization of keratinase from Bacillus subtilis isolate...
متن کاملSome probiotic properties of Lactobacillus species isolated from honey and their antimicrobial activity against foodborne pathogens
Lactobacilli commonly used as a probiotic and they can be isolated from various sources such as fermented foods and gastrointestinal tracts of humans and animals. The aims of this study were isolation and identification of lactobacilli from honey and investigation of some probiotic properties and antimicrobial effects against foodborne bacterial pathogens. A total of 88 honey samples were colle...
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 کاملAntitrypanosomal activity of some pregnane glycosides isolated from Caralluma species.
Pregnane glycosides previously isolated from genus Caralluma (C. Penicillata, C. tuberculata and C. russelliana) were tested for their antitrypanosomal activity. Penicilloside E showed the highest antitrypanosomal activity (IC(50) 1.01 microg/ml) followed by caratuberside C (IC(50) 1.85 microg/ml), which exhibited the highest selectivity index (SI 12.04). It was noticed that acylation is requir...
