Abstract excerpt
The production of extracellular catalase in a submerged culture by a number of biochemical mutants has been evaluated. Eight of these mutants showed increased extracellular catalase, the level of which ranged widely in individual cases from 44% to over 94% in comparison with the parental strain. Studies of the relationship between a criterion of selection and the frequency of mutation showed that the highest...
