Members of the
Seribacter genus are predicted to be aerobic and heterotrophic marine bacteria dwelling in surface waters. A total of 45 MAGs belonging to this genus were recovered in the 2010, 2011, 2012, 2016, 2018 and 2020 Helgoland spring blooms. This genome is estimated to be 94.2% complete with 0% redundancy. It has a GC content of 42.6% and a genome size of 2.53 Mbp. The 5S, 16S, and 23S rRNA genes were identified in the genome (Table S8).
Seribacter sulfatis belongs to the family
Seribacteraceae fam. nov., order
Opitutales, class
Verrucomicrobiae, and phylum
Verrucomicrobiota. Formerly identified as genus MB11C04 and species MB11C04, in the family MB11C04. A FISH probe for this family has been developed (probe c21-472 from
Orellana et al., 2022) and previously used to describe that members of this genus are short rods of length and width 1.2 and 1.0 µm respectively (
Orellana et al., 2022). The type species is
Seribacter sulfatis and the corresponding type material is the metagenome-assembled genome ERZ816379, which shows 99.5% ANI to a previously described representative of the MB11C04 family (MB5 from
Orellana et al., 2022).
