Keratinolytic activity
WebThe enzyme activity was determined at different temperatures and pH values. The purified keratinolytic protease from Bacillus sp. P45 was active at pH values between 6.0 and 11.0 and temperatures between 40 and 65 °C. Maximum activity was observed at pH 7.5, in which the enzyme showed a typical bell-shaped curve (Figure 2A). WebHowever, intracellular enzymes with keratinolytic activity from B. licheniformis RGI and Trichophyton gallinae were also reported [95,96]. Keratin biodegradation is thought to be composed of enzyme’s adsorption to the macromolecule’s surface (possibly by electrostatic and hydrophobic interactions) followed by the proper catalytic action.
