Abstract

Four strains of Gram-negative, aerobic, psychrotolerant, non-motile, non-pigmented bacteria were isolated from coastal sea-ice and sediment samples. These strains displayed the general chemotaxonomic and phenotypic features of members of the genus . 16S rRNA gene sequencing positioned the three isolates KMM 3646, KMM 3643 and KMM 3645 and isolate KMM 3659 in two distinct lineages within the genus , displaying less than 98·5 % sequence similarity to the type strains of other species. Genomic distinctness was supported by phenotypic differences in growth temperatures, salinity range for growth and metabolic properties. Based on a combination of phenotypic and biochemical characteristics and phylogenetic position, it is proposed that the members of these two distinct lineages represent two novel species, for which the names sp. nov. (type strain Pi2-20=KMM 3646=DSM 15387) and sp. nov. (type strain R7=KMM 3659=DSM 15389) are proposed.
