Biochemical studies on acetate non-utilizing mutants of Aspergillus terreus IRRL 16043.
The strain Aspergillus terreus IRRL 16043 can utilize glucose as well as acetate as a sole carbon source. Thirty-nine mutants were isolated from the wild-type by treatment with a chemical mutagen, N-methyl-N'-nitro-N-nitrosoguanidine (MNTG) which could not utilize acetate as a sole carbon source, and were designated as acetate non-utilizing (acu). By complementation and biochemical analyses they were divided into three functional groups, acu A, acu B and acu C lacking isocitrate lyase, malate synthase and acetyl-CoA synthetase activity, respectively.
