一株猪源屎肠球菌的分离、鉴定及益生功能初步研究

Abstract

Abstract: In this article,strain ZW002 belonged to Lactobacillus was isolated from healthy pig feces. According to the results of morphological,physiological,biochemical tests,and sequence analysis of 16S rRNA gene,strain ZW002 was identified as Enterococcus faecium,the accession number of 16S rRNA gene is JN542513. Moreover,the preliminary study of its beneficial effects,like acid resistance,bile salt tolerance and antibacterial activity was carried out. The results showed that strain ZW002 exhibited good stress tolerance and antibacterial activity,which lead strain ZW002 to be a promising candidate for probiotic research.

Key words: probiotics; Enterococcus faecium; identification; beneficial effects
