A microbial agent for fermenting low-nitrite, low-sodium sauerkraut and its preparation method include: *Leuconostoc mesenteriae* LM701 and *Lactobacillus plantarum* LP705, which have good nitrite degradation capabilities and effectively inhibit the growth of harmful bacteria such as *Escherichia coli*, *Staphylococcus aureus*, and *Salmonella* during sauerkraut fermentation. This enables low-sodium chloride fermentation, producing sauerkraut with a nitrite content ≤4 mg / kg and a crisp texture. The nitrite degradation rate of the fermented sauerkraut reaches over 63.8%. The nitrite content in the 1% edible salt concentration group is 2.69 mg / kg.

The present application relates to a kind of can prevent and treat bacterial wilt of lemon acid-loving Leuconostoc Q2-1, on February 9, 2026, be preserved in China Microorganism Strain Preservation Management Committee, and the application also relates to the application of the lemon acid-loving Leuconostoc Q2-1 in the prevention and treatment of bacterial wilt.The antagonistic strain Q2-1 of the present application is isolated from the rhizosphere of plant, and it is a kind of harmless strain to human and animal and plant, and the strain has significant antagonism to ralstonia solanacearum.In addition, volatile metabolites of antagonistic strain Q2-1 are analyzed by its plate bacteriostatic analysis, and it is found that certain metabolites in the gas produced by antagonistic strain Q2-1 have inhibitory effect on bacterial wilt pathogen CQPS-1.Therefore, the antagonistic strain Q2-1 of the present application has prevention and treatment effect on bacterial wilt of solanaceae crops, provides a new effective way for the prevention and treatment of bacterial wilt of solanaceae crops, and has good application prospect.
