Evolutive history of Caldanaerobacter subterraneus subspecies. The 16S rRNA tree was constructed using the maximum-likelihood method. aLRT values greater than 70 % are shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. Caldanaerobacter subterraneus subspecies are in bold. Other Clostridiales species are in green, Bacillales species in blue. R. rubrum was used as outgroup (in purple)
