Abstract

Abstract The utilization of n-butylamine, as the carbon and nitrogen source for the growth of Dactylium dendroides, was investigated and the presence of an inducible amine oxidase was detected. Amine oxidase synthesis is regulated through induction by amine and by nitrogen catabolite repression that is probably mediated by glutamine. The level of amine oxidase resulting from induction with n-butylamine was fourfold higher at 0.8 atm than it was at 0.2 atm O 2. This effect was also observed in the presence of 10 m M ammonium sulfate and was supressed when cycloheximide or actinomycin D was added.
