PURPOSE:To obtain L-glutamic acid through separation and growth of a strain having improved productivity, by cultivating a variant belonging to the genus Brevibacterium, etc., having resistance to formicin, capable of producing L-glutamic acid. CONSTITUTION:A variant belonging to the genus Brevibacterium or Corynebacterium, having resistance to formicin, cordycepin, tubercidin, decoyinine, psicofuranine, toyocamycin, or sangivamycin, capable of producing L-glutamic acid, is cultivated, and L-glutamic acid is formed and accumulated in the culture solution. This glutamic acid is collected. Brevibacterium lactofermentum AJ11635(FERM-P5809) (formicin resistance), etc. may be cited as the strain having resistance to a drug to be used. |
