Extracellular Protease and Chitinase Produced by a Culture of Streptomyces kurssanovii

摘要

Extracellular enzymes - a chitinase and a protease with molecular weights 22 and 32 kDa, respectively -were isolated from Streptomyxces durssanovii cells. After purification on modified regenerated chitin, the enzymes were virtually homogeneous according to denaturing PAGE. Both enzymes were found to degrade chitosan.
