Abstract
A screening was designed to isolate microorganisms having poly(γ-glutamic acid) (PGA) endohydrolase activity. Of the strains screened, TM-4222, from a soil sample, showed the highest viscosity decrement ability on PGA. It was identified to be a Myrothecium sp. The fungal production of the enzyme was slightly promoted with yeast extract and greatly promoted with· both yeast extract and PGA. The fungus was evaluated to produce PGA hydrolase of an endo-type specificity by analyzing of the reaction products.Keywords
