Further induction of amylase producing mutants from a highly proteolytic mutant strain of asppergillus flavus
돌연변이에 의한 Aspergillus flavus의 아밀라아제 생성능의 개량
Abstract
A mutant strain having increased productivity of both enzymes, protease and amylase, was obtained from A. flavus KU 153, isolatd from South Korea for its high protease production by successive ultra-violet light irradiation, Two glucoamylases from the mutant strain selected were purified from wheat branculture by successive salting out, followed by dialysis and column chromatography, and their characteristics were compared with those of the wild strain. Glucoamylase production of the mutant selected was increased about 3.3 times compared with the wild strain, and 2.1 times compared with the parental strain,
