| 摘要: |
| 从酸菜汁中分离出24株乳酸杆菌,采用牛津杯定量扩散法筛选出1株抑菌活性较高的乳酸杆菌,经鉴定为戊糖乳杆菌.排除乳酸对指示菌作用的干扰,该菌株的离心发酵液不仅对革兰氏阳性细菌有抑制作用,而且对大肠杆菌(E.coli.),沙门氏菌(Salmonella typhi)等革兰氏阴性细菌也有一定的抑制作用. |

| Screening A New Lactobacillin-Producing Stain and Its Characteristics |
|
|
| Abstract: |
| A strain of Lactobacillus was isolated from pickle juice. The fermented broth of this strain could produce an antibacterial substance with strong activity against not only some Gram-positive bacteria, like Bacil-lus subtilis and Staphylococcus aureus, but also Gram-negative bacteria including Escherichia coli and Salmonella typhi. The strain was preliminarily identified as Lactobacillus pentosus. |
| Key words: L.pentosus lactobacillin |
