摘要：

The Lactobacillus plantarum air gene encoding alanine racemase was cloned by complementation of an Escherichia call Alr(-) DadX(-) double mutant strain. Knockout of the alr gene abolished all measurable alanine racemase activity, and the mutant was shown to be strictly dependent on D-alanine for growth.
