Actinobacteria / Actinobacteria / Acidothermales

A one family, one genus order containing thermophilic, acidophilic, and cellulolytic bacteria that inhabit hot springs. Their phylogenetic position has changed, initially based on 16S rRNA analysis with a proximity to the Frankiales, but more recently whole-genome-based analysis placing away from the Frankiales, closer to the Streptosporangiales.
