摘要: Tyrosine-requiring mutant strains of Brevibacterium lactofermentum and Brevibacterium flavum which are capable of vigorous growth on culture media containing enough of a tryptophan analog to suppress growth of the parent strain and also capable of vigorous growth on media containing enough phenylalanine analog to suppress growth of the parent strain, produce more phenylalanine by aerobic fermentation of generally conventional aqueous media than the best phenylalanine-producing related microorganisms available heretofore.

摘要: Inosinic acid is produced more effectively from inosine or hypoxanthine and phosphate ions in the culture broths of hypoxanthine-requiring mutants of Corynebacterium sp. ATCC 21251 than in the culture broth of the parent strain.

摘要: Inosine and hypoxanthine are converted in the presence of phosphate ions to 5''-guanylic acid in good yield in culture media of an artificially induced mutant of Corynebacterium sp. ATCC 21251 which lacks guanosine-5''-monophosphate reductase.
