PROCESS FOR THE FERMENTATIVE PREPARATION OF L-AMINO ACIDS USING CORYNEFORM BACTERIA

摘要

A coryneform bacteria having an enhanced malate:quinone oxidoreductase gene used for the fermentative production of L-amino acids, is new. Production of L-amino acids comprises the fermentation of coryneform bacteria having a nucleotide sequence coding for malate:quinone oxidoreductase (mqo gene) which is enhanced, i.e. provides an increased intracellular mqo activity, especially by over-expression.
