    摘要: A method for efficiently producing an L-amino acid utilizing a bacterium belonging to the family Enterobacteriaceae from a fatty acid or an alcohol such as glycerol as a raw material is provided. A bacterium belonging to the family Enterobacteriaceae, having an L-amino acid-producing ability, and harboring a mutant RpsA protein having a mutation that the aspartic acid residue at position 210 is replaced with another amino acid residue is cultured in a medium containing a carbon source selected from a fatty acid and an alcohol, and an L-amino acid is collected from the medium thereby to produce the L-amino acid.
