嗜酸乳杆菌LAJ90菌株部分生物学特性的研究

STUDIES ON SOME BIOLOGICAL CHARACTERISTICS OF LACTOBACILLUS ACIDOPHLLUS LAJ90

采用MRS培养基,对嗜酸乳杆菌LAJ90菌株的耐酸、耐胆汁盐及耐药性等部分生物学特性进行了研究。结果表明,该菌株能耐受0.1％～0.5％的猪胆盐,对pH1.5～4.5的酸度有较强的抵抗力,对青霉素和氨苄青霉素均具有中敏特性。

Some biological characteristics such as the tolerance to acidity, bile salt and antibiotic of Lacto-bacillus acidophilus LAJ90 was studied by using MRS medium. The results were as follows; the strain LAJ90 could resist 0.1%~ 0.5% bile salt and the acidity of pH1.0-pH4.0, the tolerances to Penicillin and A-PN were both medium sensitivity.
