Isoleucine 2-epimerase (ILEP) is a novel branched-chain amino acid racemase isolated from Lactobacillus buchneri. In this study, we examined production of free d-branched-chain amino acids such as d-valine, d-leucine, and d-allo-isoleucine, using lactic acid bacteria carrying homologs to ILEP. Twelve
