摘要和关键词

摘要: 文章通过构建进化树研究食窦魏斯氏菌 W. cibaria BWL4 的种属亲缘性，利用生长曲线分析 W. cibaria BWL4 作为乳酸菌的生物学共性，通过体外实验探讨其耐酸、耐胆盐以及抑菌谱特性。研究发现：W. cibaria BWL4 具有较好的产酸性能和耐酸、耐胆盐的特性；其菌液对黄曲霉菌、灰霉菌和扩展青霉菌均有不同程度的抑制作用；W. cibaria BWL4 的细胞上清液对大肠杆菌、单核细胞增生李斯特菌、丙二酸盐克罗诺 362、沙门氏菌、金黄色葡萄球菌均有明显的抑制效果。该结果为进一步研究 W. cibaria BWL4 在乳制品中的应用奠定了基础。

Abstract and Keywords

Abstract: This paper studied the species affinity of W. cibaria BWL4 by constructing an evolutionary tree, analyzed the biological commonalities of W. cibaria BWL4 as a lactic acid bacterium by the growth curve, and explored its acid resistance, bile salt resistance and antibacterial spectrum characteristics through in vitro experiments. The research found that W. cibaria BWL4 had better acid production performance and the characteristics of acid and bile salt resistance. Its bacterial liquid had varying degrees of inhibitory effects on Aspergillus flavus, Botrytis cinerea, and Penicillium expansum. The cell supernatant of W. cibaria BWL4 had significant inhibitory effects on Escherichia coli, Listeria monocytogenes, Cronobacter malonaticus 362, Salmonella, and Staphylococcus aureus. This finding laid the foundation for further research on the application of W. cibaria BWL4 in dairy products.

Keywords: W. cibaria BWL4; growth curve; acid resistance; bacteriostatic action; biological characteristics
