Sixty strains of lactic acid bacteria (LAB) were isolated from koumiss in Xinjiang, China. Most of the strains had antimould activity, and the Lactobacillus plantarum IMAU10116 strain had greatest inhibitory activity against Penicillium roqueforti. Meanwhile, it could also inhibit some bacteria such as Escherichia coli and Listeria innocua. The antimould substance had high thermal stability. Maximum antimould activity was observed between pH 3.0 and 3.8 (initial pH), but it decreased when pH was adjusted to a level between 3.8 and 7.0. It was sensitive to proteinase‐K and trypsin, but its inhibitory activity did not change after treatment with dispase.
