Based on results of Table 1 and Table 2, the strain KL-12, with higher antibacterial activity to pathogens and stronger tolerance to gastric juice and bile acid, was selected to use as a starter for subsequent fermentation experiments. The selected strain KL-12 was identified to belong to the L. plantarum group based on 16S rRNA gene sequencing (99.60% similarity to GeneBank sequences, Fig. 1).
