The invention discloses a strain of Enterococcus lactis B3, which is preserved in the China Center for Type Culture Collection with a deposit number of CCTCC NO: M 20211140. The strain is derived from glutinous rice cake and has high nitrite tolerance. When the nitrite concentration is 1%, it can still grow, which is significantly higher than that of lactic acid bacteria isolated from other traditional fermented foods; at the same time, the strain also has high nitrite degradation ability, and the highest degradation rate can reach 99.53%. Therefore, Enterococcus lactis B3 can not only be used as a new biological resource for the processing of glutinous rice cakes, but also can be added to the starter of fermented foods such as kimchi, sour meat, sour fish, etc. to reduce nitrite and Improve food safety. |
