The invention relates to a lactobacillus delbrueckii strain, application of the lactobacillus delbrueckii strain and a method for producing L-lactic acid through fermentation, and the lactobacillus delbrueckii strain is lactobacillus delbrueckii Ldbzh1101, and the strain preservation number is CGMCC (China General Microbiological Culture Collection Center) No.26078. The strain has unique physiological and biochemical characteristics and can be researched and applied in the fields of scientific research, industry and the like. In the application process of producing the polymer-grade L-lactic acid by a fermentation method, the strain stability is greatly improved, the fermentation culture conditions are extensive, the yield and the conversion rate are remarkably improved compared with those of the original strain, the optical purity of the L-lactic acid produced by the method can reach 99.9%, and the method is more suitable for producing polylactic acid and has a better industrial application ...
