A facultative psychrotrophic lactic acid bacterium isolated from fresh fish was identified as Carnobacterium piscicola on the basis of carbohydrate utilization, G + C content and 16S RNA analysis. Its bacteriocin, designated carnocin UI49, is produced during the mid-exponential phase of growth at temperatures between 15 degrees C and 34 degrees C. Carnocin UI49 is active against a large number of closely-related lactic acid bacteria including carnobacteria, lactobacilli, pediococci and lactococci. Furthermore, the bacteriocin has a bactericidic mode of action which results in lysis of sensitive cells. Maximum bactericidal activity is observed at 34 degrees C with a decrease in activity down to 15 degrees C where it is completely abolished.
从鲜鱼中分离出的一种兼性嗜冷乳酸杆菌，根据碳水化合物利用情况、G + C含量和16S RNA分析，被鉴定为嗜鱼肉杆菌。其细菌素命名为鱼菌素UI49，在15摄氏度至34摄氏度之间的温度下，于生长指数中期产生。鱼菌素UI49对大量密切相关的乳酸菌具有活性，包括肉杆菌、乳杆菌、片球菌和乳球菌。此外，该细菌素具有杀菌作用方式，可导致敏感细胞裂解。在34摄氏度时观察到最大杀菌活性，在15摄氏度时活性降低，在该温度下活性完全消失。
