Screening and Preliminary Identification of a Lactic Acid Bacterium Strain with the Capacity of Nitrite Degradation from Sanjiang Pickled Potherb Mustard

Abstract

Abstract: A strain of lactic acid bacteria with strong ability to degrade nitrite was screened from pickled potherb mustard made in Sanjiang town, Jiangxi province. The strongest ability of the strain to degrade nitrite averagely reached 32.66 μg/mL during 68 h of fermentation. The results of 16s rRNA sequencing showed that this strain was 98% homologous to Lactobacillus fermentum PL9005. Polygenetic analysis indicated that this strain belonged to Lactobacillus fermentum.

Key words: lactic acid bacteria, nitrite degradation, screening, identification
