A hotspot of diversity: novel species isolated from Baltic Sea sediments delineate a sympatric species complex.

Two bacterial strains, SP1S1-4 and SP2S1-2, were isolated from sediment samples collected in the Stockholm archipelago in November 2021. Following whole-genome sequencing, these strains were identified as tentatively belonging to two novel genospecies, based on digital DNA-DNA hybridization, as implemented in the Type Strain Genome Server. , and were, in this order and within a narrow genomic relatedness range, their closest genotypic relatives.

sp. nov. and sp. nov., isolated from Baltic Sea water and sediments.

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.
