Abstract: 92 Strains of lactic acid bacteria were isolated and identified from many sorts of pickles. Four strains, named Leu. 1, Leu.2, Lact.1 and Lact.2 were selected for having excellent characteristics in acid production and fermentation flavor. Leu.1 and Leu.2 were identified as Leuconostoc mesenteroides subsp. mesenteroides. Lact.1 and Lact.2 were identified as Lactobacillus casei subsp. casei and Lactobacillus plantarum respectively. In cabbage fermentation at 10℃, the acid production and fermentation flavor of inoculated fermentation were much better than those of natural fermentation. Leu.1 and Leu.2 produced acid quickly in the prophase of fermentation. The pHs of cabbage brine inoculated with these two strains both 3.67 after 11d of fermentation, while the pHs of that inoculated with Lact.1 and Lact.2 both reached pH 3.30. The fermentation characteristics of these four strains were also studied.

Key words: pickles, lactic acid bacteria, isolation and identification, fermentation in low temperature
