Abstract

A slightly beige-white pigmented, Gram-staining-negative, rod-shaped bacterium, strain M1A1T, was isolated from seawater samples obtained in Fildes Bay, Antarctica (62°12′ S 58° 57′ W). Phylogenetic analysis based on nearly full-length 16S rRNA gene sequences showed that the isolate shared 98.4% 16S rRNA gene sequence identity to the type strain of Psychromonas arctica, but less than 97% 16S rRNA gene sequence similarities to all other species of the genus Psychromonas. DNA–DNA hybridization with Psychromonas arctica DSM 14288^T showed low values (21%, reciprocal 27%). The main cellular fatty acid of strain M1A1^T was summed feature 3 fatty acids (C_{16: 1}ω7c/C_{16: 1}ω8c), followed by C_{16: 0}. Based on phylogenetic, chemotaxonomic, genomic and phenotypic analyses, we propose a novel species of the genus Psychromonas with the name Psychromonas aquatilis sp. nov. and the strain M1A1^T (=CIP 111183^T=CCM 8710^T=LMG 29766^T) as type strain.
