| 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 protease when cultivated in mineral medium containing 1% of wool straight off sheep as sole carbon and ni ... | 2013 | 23936776 |
