sp. nov., isolated from a black rock cod fish () from the Chilean Antarctic.

An orange-pigmented, oxidase-positive bacterial strain (I-41R45), isolated from the kidney of a black rock cod fish sampled in the Chilean Antarctic was studied in a polyphasic taxonomic investigation. Cells of the isolate were coccoid and stained Gram-negative. A comparison of the 16S rRNA gene sequence of strain I-41R45 with sequences of type strains of most closely related species showed highest sequence similarities to (98.4 %), (98.3 %), and (both 98.2 %). 16S rRNA gene sequence similarities to all other species were below 97 %. The draft genome of strain I-41R45 had a size of 4.59 Mb with a DNA G+C content of 65.26 mol% and included the prediction and annotation of 4426 coding genes, 1973 protein-coding genes and 46 tRNAs. The fatty acid profile of strain I-41R45 consisted mainly of the major fatty acids C 79t12t and C, typical of the genus . DNA-DNA hybridizations between I-41R45 and type strains of and resulted in similarity values of 45 % (reciprocal 26 %), 66 % (reciprocal 61 %), and 29 % (reciprocal 36 %), respectively. DNA-DNA hybridization results, together with the differentiating biochemical and chemotaxonomic properties, showed that strain I-41R45 represents a novel species, for which the name sp. nov. (type strain I-41R45=CCM 8875=CIP 111632), is proposed.
