What is "sphaerobacter"

Sphaerobacter is a genus of bacteria. When originally described it was placed in its own subclass (Spahaerobacteridae) within the class Actinobacteria. Subsequently phylogenetic studies have now placed it in its own order Sphaerobacterales within the phylum Chloroflexi. Up to now there is only one species of this genus known ( Sphaerobacter thermophilus).
