Isolation of mutants with improved production of cAMP from Microbacterium sp. no. 205 (ATCC 21376).
Mutants were isolated from Microbacterium sp. no. 205 (ATCC 21376) producing 13-30 mM cyclic adenosine 3',5'-monophosphate (cAMP) by salvage biosynthesis, through sequential improvements of the bacterium for the purpose of improving cAMP production. The mutants produced 50-75 mM cAMP on 100 mM inosine 5'-monophosphate as a precursor. Mutants resistant to the inhibition of growth by cAMP at high concentrations were isolated; the resistance was one of four characteristics effective for improved production of cAMP.
