Genome sequence of the pink to light reddish-pigmented Rubellimicrobium mesophilum type strain (DSM 19309(T)), a representative of the Roseobacter group isolated from soil, and emended description of the species.

ABSTRACT: Rubellimicrobium mesophilum Dastager et al. 2008 is a mesophilic and light reddish-pigmented representative of the Roseobacter group within the alphaproteobacterial family Rhodobacteraceae. Representatives of the Roseobacter group play an important role in the marine biogeochemical cycles and were found in a broad variety of marine environments associated with algal blooms, different kinds of sediments, and surfaces of invertebrates and vertebrates. Roseobacters were shown to be widely distributed, especially within the total bacterial community found in coastal waters, as well as in mixed water layers of the open ocean. Here we describe the features of R. mesophilum strain MSL-20(T) together with its genome sequence and annotation generated from a culture of DSM 19309(T). The 4,927,676 bp genome sequence consists of one chromosome and probably one extrachromosomal element. It contains 5,082 protein-coding genes and 56 RNA genes. As previously reported, the G+C content is significantly different from the actual genome sequence-based G+C content and as the type strain tests positively for oxidase, the species description is emended accordingly. The genome was sequenced as part of the activities of the Transregional Collaborative Research Centre 51 (TRR51) funded by the German Research Foundation (DFG).
