Abstract

1377208 L-isoleucine TANABE SEIYAKU CO Ltd 26 Nov 1971 [30 Nov 1970] 54944/71 Heading C2C L-isoleucine is prepared by cultivating a mutant of Serratia marcescens, which is isoleucine hydroxamate-resistant or isoleucine hydroxamate and α-aminobutyric acid-resistant, in a nutrient medium under aerobic conditions and recovering the accumulated L-isoleucine from the fermentation broth. The cultivation may take place in the presence of 0À05-5 w./v. per cent, based, on the total volume of the medium, of L-threonine, L-homoserine or L- aspartic acid. The relevant mutants may be obtained from wild type strains by U.V. irradiation or by treatment with a mutagen. Specific Serratia marcescens are A.T.C.C. Nos. 21740 and 21741.
