Complete genome sequence of Sphaerobacter thermophilus type strain (S 6022 T)

Abstract

Sphaerobacter thermophilus Demharter et al. 1989 is the sole and type species of the genus Sphaerobacter, which is the type genus of the family Sphaerobacteraceae, the order Sphaerobacterales and the subclass Sphaerobacteridae. Phylogenetically, it belongs to the genomically little studied class of the Thermomicrobia in the bacterial phylum Chloroflexi. Here, the genome of strain S 6022 T is described which is an obligate aerobe that was originally isolated from an aerated laboratory-scale fermentor that was pulse fed with municipal sewage sludge. We describe the features of this organism, together with the complete genome and annotation. This is the first complete genome sequence of the thermomicrobial subclass Sphaerobacteridae, and the second sequence from the chloroflexal class Thermomicrobia. The 3,993,764 bp genome with its 3,525 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
