A novel Lactobacillus plantarum and use thereof are disclosed, which fall within the technical field of microorganisms. The Lactobacillus plantarum tlj-2014 is deposited in China General Microbiological Culture Collection Center (CGMCC) under CGMCC Accession No. 9405. With the strain, the lactic acid production rate can be up to 35 g/L/d, and the concentration of lactic acid after 71 hrs of fermentation is up to 95 g/L. The Lactobacillus plantarum is acid tolerant, survives well at pH 1.80, can degrade the nitrite quickly with a decomposition capability of up to 9.8 mg/h/kg, and is tolerant to 1% bile salt. When the strain is used in production of pickles, the nitrite concentration is less than 5 mg/kg throughout the entire fermentation process, which is far below the content specified in the national standard GB2714-2003. |
