A new keratinase extracted from Streptomyces matensis (MPLS-1) was isolated and purified in this study. Solid ammonium sulfate was selected to precipitate the enzyme. Its proper adding mass was also determined. Through solid ammonium sulphate precipitation and liquid chromatography via the DEAE-Sephadex-LH 100 using the feather powder as substrate, 2.4-fold purification with a yield of 26.66% was obtained. The purification effect was determined through SDS-PAGE, and the molecular weight of
