Abstract

Two bacterial strains, SP1W3 and SP1S2-7, were isolated from samples of water and sediments collected in Vaxholm, a town located on the Stockholm archipelago in the Baltic Sea, in November 2021. The strains were identified as novel genomic species within the genus , based upon comparative analysis of whole genome sequence data. Strain SP1W3 (genome size, 5.20 Mbp; G+C content, 46.0 mol%), isolated from water, was determined to be most closely related to ATCC-BAA 1207 and NCTC 10735, with digital DNA–DNA hybridization (dDDH) values of 61.7% and 60.4 %, respectively. Strain SP1S2-7 (genome size, 4.26 Mbp; G+C content, 41.5 mol%), isolated from sediments, was observed to be most closely related to JCM17801, with a pairwise dDDH value of 33.8 %. Polyphasic analyses of physiological and phenotypic characteristics, in addition to genomic analyses, confirmed that each of these two strains represent distinct, novel species within the genus , for which the names sp. nov. (type strain SP1W3=CCUG 76164=CECT 30651) and sp. nov. (type strain SP1S2-7=CCUG 76165=CECT 30652) are proposed.
