摘要
目的分析传统泡菜中乳酸菌的多样性。方法采用生理生化学特性和16S rRNA基因序列同源性分析相结合的方法,对传统泡菜中筛得的46株菌进行鉴定。结果菌株分布于乳杆菌属、肠球菌属、葡萄球菌属和片球菌属4个属的9个种,更为重要的是在泡菜中发现有Lactobacillus namurensis和巴氏葡萄球菌的存在。结论泡菜中存在着丰富的乳酸菌。
Objective To analyse the biodiversity of Lactic acid bacteria from traditional fermented vegetables.Method The 46 LAB strains isolated from traditional fermented vegetables were identified with physiological and biochemical characteristics and 16S rRNA gene sequencing.Result The LAB isolates belonged to 4 genera and 9 species,including Lactobacillus,Enterococcus,Staphylococcus and Pediococcus.Moreover,L.namurensis and S.pasteuri had been found in these traditional fermented vegetables.Conclusion There is a high level of biodiversity among LAB in traditional fermented vegetables.
