Keratinolysis by Absidia cylindrospora and Rhizomucor pusillus: biochemical proof.

R C Rajak1, H K Malviya, H Deshpande, S K Hasija.   

Abstract

Absidia cylindrospora and Rhizomucor pusillus causal agents of phycomycoses, were cultured on sterile natural keratins in a mineral solution and the keratin degradation products analyzed. The excess of sulphur was removed by oxidation to inorganic sulphate and thiosulphate, which were the main products of sulphitolysis of keratin. The proteolytic activity of the two fungi depended on the nature of the keratin substrate. Human scalp hair was the most favoured keratin substrate by both the fungi.
