摘要

METHYLOPHILUS BACT E RIA" MEASURES TO PRODUCE AN L-AMINECIDE AND TO PRODUCE BACTERIAN CELL FROM A METHYLOPHILUS BACTERIARY WITH AN AUDIENT TEOR OF AN L-AMINHICIDED, E, DNA." An L-amino acid is produced by cultivating a Methylophilus bacterium that can develop using methanol as a main carbon source and has L-amino acid producing capacity, for example,a bacterium Methylophilus in which diydrrodipicolinate synthase activity and aspartokinase activity are increased by transformation through introduction into cells of a DNA coding for dihydrorodipicolinate synthesise that does not suffer from inhibition of feedback by L-lysine and DNA encoding aspartokinase that does not suffers from feedback inhibition by L-lysine or a Methylophilus bacterium manufactured to be a casamino acid auxotic, in a medium containing methanol as a main carbon source, to produce and accumulate an L-amino acid in culture and collect the L-amino acid from the crop.
