Amino acids production with mutant strains of Brevibacterium sp. M-27

Amino acids production with mutant strains of Brevibacterium sp. M-27

The mutation of the strain of Brevibacterium sp. M-27 using N-methyl-N'-nitro-N-nitrosoguanidine was studied with the aim to prepare new producers of L-lysine and further amino acids. The work results in a group of auxotroph mutant strains, pigmented and auxotroph pigmented mutants. There were...

Zusammenfassung:The mutation of the strain of Brevibacterium sp. M-27 using N-methyl-N'-nitro-N-nitrosoguanidine was studied with the aim to prepare new producers of L-lysine and further amino acids. The work results in a group of auxotroph mutant strains, pigmented and auxotroph pigmented mutants. There were obtained the suspected producers of alanine, valine and glutamine acid there. Among the many-fold dependent mutants, the strains with increased production on L-lysine exist.
