1413236 L - Lysine KANEGAFUCHI CHEMICAL INDUSTRIES CO Ltd 31 July 1973 [2 Aug 1972 (2)] 36471/73 Heading C2C L-Lysine is made by cultivating aerobically a mutant strain of a microorganism belonging to the genus Pseudomonar or Achromobacter in a culture medium containing a hydro-carbon at the main carbon source, said mutant strain being resistant to at least one amino-acid selected from L-valine,α-amino-n-butyric acid, norvaline, # - hydroxynorvaline,α- amino - # - chloro - nbutyric acid and L-threonine. Preferably the microorganism is a mutant strain of Pseudomonar brevis ATCC 21940 (e.g. ATCC 21941) or a mutant strain of Achromobacter coagulans ATCC 21934 (e.g. ATCC 21935 or 21936). The culture medium includes the convential nitrogen sources and inorganic salts and may also include a melting agent (e.g. polyoxyethylene mono- or tri-oleate).
