HAIR REMOVAL POTENTIAL OF KERATINASE PRODUCED BY BACILLUS SPECIES ISOLATED FROM FEATHER WASTE

Keratins are tough, fibrous proteins found as the major protein component in hair. Chemical hair removal is harsh and results severe toxicity pollution, hence, a need for non-chemical enzymatic process. The aim of this study to characterise keratinase from isolated keratin-degrading Bacillus licheniformis-K51, subtilis-K50 sp.-K53 investigate its potential removal. collagenolytic ability keratinases obtained was determined using standard methods. depilatory (directly part constituent formulated cream) vitro on goat skin vivo Wistar rat. Purified licheniformis-K51 (EZYKer-51), (EZYKer-50) (EZYKer-53) did not show significant activities. In treatment with EZYKer-51 showed total within 24 hours partial EZYKer-50 EZYKer-53. cream containing highest keratinolytic activity (22.20±0.63 U/mL) followed by (20.52±0.46 EZYKer-53 (17.06±0.81 U/mL). action took 40 min, while that commercial achieved 20 min. Keratinase exhibited complete hair-removal function which makes it potentially suitable industrial processes involving
