乳酸菌的分离及抑菌能力的初步研究

Preliminary study of separation and antibacterial ability of lactic acid bacteria

从不同的标本中分离出五株乳酸菌D1、Y1、D2、EM2、EM1,并对其进行抑菌实验。结果发现Y1对大肠杆菌的抑菌作用较强;EM2对枯草杆菌的抑菌作用较强;D1对绿脓杆菌的抑菌作用较强;D2对金黄色葡萄球菌的抑菌作用较强。

Five strain of Lactic Acid Bacteria （D1 ,Y1, D2,EM1,EM2） are separated from different samples. After identified and antibacterial experiment, It is found that Y1 have stronger antibacterial ability to Escherichia coli; EM2 have stronger antibacterial ability to Bacillus subtilis.D1 have stronger antibacterial ability to Bacillus aeruginosum.D2 have stronger antibacterial ability to Staphylococcus aureus.
