Brassica juncea var. tumida Tsen (Brassicaceae) is a feature vegetable in Fuling, Chongqing, and is the raw material for the famous salted food "Fuling mustard" pickles. Sichuan paocai is a lactic acid-fermented and mildly salted vegetable in China consumed as a side dish with the main meal or appetizer. The pickling method is simple. In a typical procedure, various vegetables, such as radish, cabbage, cowpea, and cucumber, are immersed in a 6%-8% salt solution containing red pepper, garlic, ginger, sugar, and other spices in a sealed jar covered with water. The fermentation is completed approximately 1 and 2 weeks during the summer and winter at ~25°C-35°C and ~8°C-15°C, respectively. In the present study, B. juncea var. tumida Tsen (Brassicaceae) was used to produce Sichuan paocai. Homemade pickled vegetables are usually spontaneously fermented using the epiphytic microbes on the surface of the vegetables. Various microbes, for example, lactic acid bacteria (LABs) and acetic acid bacteria and yeast, are involved in fermentation, during which the variety and quantity of microorganisms constantly change (Zhao, Li, Jiang, Deng, & Kneifel, 2016). To provide uniform fermented products, selecting suitable strains to initiate fermentation is necessary. Various LABs have been used as starter culture, including Lactobacillus brevis
