Objective To identify and analyze a dominant lactic acid bacteria strain CGMCC 10624 isolated from the traditional steamed buns Jiaozi by polyphasic taxonomy. Methods The lactic acid bacteria strain CGMCC 10624 was isolated and purified from the traditional steamed buns Jiaozi. Taxonomic status of the CGMCC 10624 was conducted by bacterial morphology observation, phylogenetic analysis based on the 16S rRNA gene sequence and physiological and biochemical characteristics identification method based on carbon source metabolic utilization. Results The lactic acid bacteria strain CGMCC 10624 was identified as Weissella cibaria. Conclusion A dominant lactic acid bacteria strain was isolated and purified from the traditional steamed buns Jiaozi in this study which would lay the foundation of resources for its study on the biologic function and production of composite microbial agent containing lactic acid bacteria and yeasts.
