为探索细胞表面特性与抗菌能力之间的关系,对干酪乳杆菌Zhang(Lactobacillus casei Zhang)、动物双歧杆菌V9(Bifidobacteria.animalis V9)、动物双歧杆菌Bb12(Bifidobacteria.animalis subsp.lactic Bb12)及干酪乳杆菌Shirota(Lactobacillus casei Shirota)的菌体表面特性(菌体凝集特性、表面疏水特性)及对肠道致病菌的抑制特性进行了研究,结果显示:各菌株自凝集能力随培养时间的延长均呈上升趋势;对致病菌的凝集率随益生菌、致病菌和培养时间的变化而不同;具有较高自凝集能力的菌株,其疏水能力及对致病菌的凝集能力同样较高;各益生菌对致病菌的凝集能力与其产生抑菌物质的抑菌能力无明显关系。
To explore the relationship between cell surface properties and antibacterial ability, the activity of Lactobacillus casei Zhang, Bifidobacteria V9, Bifidobacterium Bifidum Bb12, (Lactobacillus casei Shirota) on the surface characteristics (bacterial cell aggregation, surface hydrophobic properties) and inhibition of intestinal pathogenic bacteria were studied, the results showed that: the ability of each strain of self-agglutination with the incubation time The leaching rate of pathogenic bacteria varied with probiotics, pathogenic bacteria and culture time; the strains with higher self-agglutination ability had the same hydrophobicity and the same ability of agglutinating pathogens Higher; each probiotic bacteria agglutination ability of pathogens and their antibacterial substances inhibitory effect no significant relationship.
