Abstract

SUMMARY

Mutants of 8602 were isolated which, unlike the wild type, were able to grow with butyramide as a carbon source. Six mutants derived from the constitutive strain 11 were shown to produce an enzyme (B amidase) with altered electrophoretic mobility and altered substrate specificity. The apparent for butyramide of the B amidase was about a tenth of that of the A amidase and the was about ten-fold greater. A further mutation produced mutants able to grow on valeramide.
