Abstract

Strain K1T, isolated from the gastrointestinal tract of Atlantic salmon (Salmo salar), has the capacity to inhibit the growth of the fish pathogens Vibrio anguillarum and Aeromonas salmonicida. Strain K1T is a motile Gram-positive psychrophilic rod that lacks both catalase and oxidase, which does not grow on acetate containing media, but grows at pH 9 and in TSB with up to 6% sodium chloride content. Strain K1T is facultatively anaerobic and tryptone as a sole source of nutrient promotes growth. The most abundant cellular fatty acid of strain K1T is oleic acid (18:1cis9). Based on 16S rDNA sequence comparisons, it is suggested that strain K1T is phylogenetically closely related to C. alterfunditum. However, the unique phenotypic attributes of strain K1T suggest that it represents a new species. The name Carnobacterium inhibens is proposed, for which the type strain is K1T (= CCUG 31728T).

从大西洋鲑鱼(Salmo salar)肠道中分离的抑制肉杆菌。
菌株K1T是从大西洋鲑鱼(Salmo salar)的胃肠道中分离出来的,具有抑制鱼类病原体鳗弧菌和沙门氏菌气单胞菌生长的能力。菌株K1T是一种缺乏过氧化氢酶和氧化酶的运动革兰氏阳性嗜冷棒,它不能在含乙酸的培养基上生长,但可以在pH 9和氯化钠含量高达6%的TSB中生长。菌株K1T是兼性厌氧的,色氨酸作为唯一的营养来源促进生长。菌株K1T细胞中最丰富的脂肪酸是油酸(18:1 . 5)。基于16S rDNA序列的比较,认为菌株K1T在系统发育上与C. alterfundum亲缘关系较近。然而,菌株K1T独特的表型特征表明它是一个新种。建议命名为Carnobacterium inhibens,其类型菌株为K1T (= CCUG 31728T)。
