Isolation and Partial Characterizatıon of Keratinase from Trichophyton sp.

Abstract

Keratinase enzyme production was accomplished from Trichophyton sp. Tr-9 in minmal medium containing feather meal. Enzyme was purified with Ammonium sulfate, Sephadeks G-100 and DEAE Sepharose column. Maxiumum keratinolitik activity was obtained at pH 7.5 and 37°C. Enzyme was higly stabil between pH 5.5-7.5 and 20-40oC. With the SDS-Page analysis of the enzyme, molecular weight of the enzyme was calculated as 34 kDa. CaCI2 (5mM) had a stimultory effect (148%) on enzyme. On the other hand, EDTA (5mM) and SDS (%1) inhibited enzyme acitivity up to 49% and 49%, respectively. PMSF (1- 5mM) has strongly inhibited enzyme. As a result, physico-chemical properties of the enzymeshowed that Trichophyton sp. Tr-9 could be useful in various industrial and biotechnological applications.
