''Sphaerobacter'' is a genus of bacteria. When originally described it was placed in its own subclass (Spahaerobacteridae) within the class

Actinomycetota The ''Actinomycetota'' (or ''Actinobacteria'') are a phylum of all gram-positive bacteria. They can be terrestrial or aquatic. They are of great economic importance to humans because agriculture and forests depend on their contributions to s ...

. Subsequently, phylogenetic studies have now placed it in its own order Sphaerobacterales within the phylum Thermomicrobiota. Up to now there is only one species of this genus known (''Sphaerobacter thermophilus''). The closest related cultivated organism to S. Thermophilus is the Thermomicrobium Roseum and has an 87% sequence similarity which indicates that S. Thermophilus is one of the most isolated bacterial species.
