Special Habitats Bacteriocin Produced By Lactobacillus Isolation, Identification And Probiotic Properties Are Analyzed

This　research's　order　is　to　isolate　lactic　acid　bacteria　that　can　produce　bactericin　and　lactic　acid　during　fermention　from　the　vagina　of　60　healthy　women.　The　19　strains　of　bacilliform　bacteria　were　identified　by　biochemical　tests,　part　of　their　16S　ribosomal　DNA　were　amplified,　sequenced,　and　phylogenetically　placed.　The　results　showed　that　the　lactic　acid　bacteria　were　belongs　to　those　special　homotype　fermention　types　of　Lactobacillus.9　strains　belong　to　Lactobacillus　gasseri,　one　does　Lactobacillus.salivarius　and　the　other　9strains　do　Lactobacillus.crispatus.　They　could　produce　lactic　acid , bactericin　,and　H2O2　except　3　of　them,remaining　the　acid　circumstances　and　inhibit　the　growing　of　the　other　pathogentic　bacteria,　such　as　Staphylococcus　aureus,　Escherichia.coli　etc.　They　could　not　inhibit　the　spherical　bacteria　that　are　isolated　from　the　same　circumstance　and　themselves　except　one　strain　46-2.　So　these　Lactobacillus　strains　that　are　isolated　from　the　bodies　have　several　effective　actions　to　keep　the　vaginal　healthy　balance.　We　should　use　these　Lactobacillus　strains　to　make　thep　robiotics,　according　to　the　humanity　current　of　the　vaginal　health　protection.
