Abstract:

The isolation and identification of lactic acid bacteria from 8 kinds of fruits collected from different regions in XinJinag were carried out by using MRS，M17 and other two different culture medium. The phylogenetic relationship was identified based on analysis of the 16s rRNA gene sequences；and the bacteriocin-producing lactic acid bacteria strains were screened by using the Oxford cup method. A total of 90 lactic acid bacteria strains were isolated from all samples，and 15 representative strains were obtained based on the rep-PCR fingerprint classification. According to the 16s rRNA gene sequence analysis，15 representative strains mainly belong to genus of Lactobacillus （8 strains）， Leuconostoc （6 strains）， Lactococcus （1 strain） respectively. A total of 8 lactic acid bacteria strains can inhibit the growth of S taphylococcus aureus ， Bacillus subtilis and Listeria monocytogenes ，were screened out by using the Oxford cup method，and they have great potential application for their possible use as a natural biopreservatives in the food industry.
