Abstract

PURPOSE: To prepare L-cysteine or L-cystine, useful as an antidote, a tonic, and an experimental reagent, by culturing bacteria belonging to Paracolobactrum, Micrococcus, Escherichia, Klebsiella, or Bacillus genus.
CONSTITUTION: Bacteria belonging to Paracolobactrum, Micrococcus, Escherichia, Klebsiella, or Bacillus genous, and capable of producing L-cysteine or L-cystine, e.g. Paracolobactrum coliforme KY 8482 (FERM-P Mo.4291, selenocystine resistant) derived by the mutagenic treatment of ATCCA 21186 strain, are aerobically cultured in a nutrient medium at 20-40°C, pref. under nearly neutral conditions for 1-5 days.
