Abstract

A differential medium was developed to distinguish between malate-decarboxylating (MDC ⁺ ) and -non-decarboxylating (MDC ⁻ ) strains of Lactobacillus plantarum. MDC ⁻ strains produced a visible acid reaction in the medium, whereas MDC ⁺ strains did not. Use of the medium allowed for rapid screening and isolation of mutagenized cells that had lost the ability to produce CO ₂ from malate.
