Abstract

The present invention relates to microorganisms and processes for the efficient preparation of L-amino acids such as L-methionine. In particular, the present invention relates to microorganisms and processes in which the formation and/or accumulation of homolanthionine in the methionine pathway is reduced and/or prevented.
