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).
