Bastian Herzog

Research Interests:

Keratinases are enzymes with the ability to degrade keratin, the main structural protein of hair and skin. My work focuses on the identification of a keratinase being highly specific for hair and skin keratin that might be applicable to soften/remove hair and as active ingredient in anti-aging products. Environmental samples as well as known bacteria strains are screened for their keratin biodegradation, characterized and purified.
