Lactobacillus for producing lactic acid and H2O2 and application of lactobacillus

The invention discloses lactobacillus for producing lactic acid and H2O2 and an application of the lactobacillus. The lactobacillus is lactobacillus gasseri or lactobacillus crispatus, wherein the preservation number of the lactobacillus gasseri is CGMCC No. 15815 or CGMCC No. 15816; the preservation number of the lactobacillus crispatus is CGMCC No. 15813 or CGMCC No. 15814. The lactobacillus gasseri and lactobacillus crispatus provided by the invention have extremely strong lactic acid and H2O2 production ability, have good ability to adhere to vaginal epithelial cells, and can effectively inhibit reproduction of pathogenic bacteria like Gardner bacteria and Candida albicans in in-vivo and in-vitro experiments. 本发明公开了一种产乳酸和HO的乳杆菌及其应用。所述的乳杆菌为格氏乳杆菌(Lactobacillus gasseri)或卷曲乳杆菌(Lactobacillus crispatus)，所述格氏乳杆菌的保藏编号为CGMCC No.15815或者CGMCC No.15816；所述卷曲乳杆菌的保藏编号为CGMCC No.15813或者CGMCC No.15814。本发明的格氏乳杆菌、卷曲乳杆菌能够具有极强的产乳酸和HO能力、具有很好地黏附阴道上皮细胞的能力，并且体内和体外实验中均能够有效地抑制加德纳菌、白念珠菌等病原菌的繁殖。
