Amino acid production from methanol by Methylobacillus glycogenes mutants: Isolation of L-glutamic acid hyper-producing mutants from M. glycogenes strains, and derivation of L-threonine and L-lysine-producing mutants from them

L-Glutamic acid (Glu) hyper-producing mutants were isolated from Methylobacillus glycogenes ATCC 21276 and ATCC 21371 during the screening of amino acid auxotrophs. iA111, derived from ATCC 21276, and 1009 (Phe - ), derived from ATCC 21371, produced about 10 times as much Glu as the wild type strain...
