Phylogenetic reconstruction of potential thermophilic hydrogenogenic carboxydotrophic phylotypes of the Phylum Firmicutes. The 16S rRNA sequences used in this analysis are listed in Online Resource 6. Other but identical sequences to their leaves are shown in parenthesis (only one sequence per genome are shown). The phylotype sequences obtained in this study are expressed by ‘operational taxonomic unit (OTU)’ prefix. Microbes possessing CODH − ECH gene clusters and Carboxydothermus pertinax (cpu_RS09700) are shown in red font. Nodes supported by a bootstrap value greater than 80% are indicated by black circles. The bubble plots which are shown at the right of OTUs display the distribution pattern of each phylotype. Abundance is indicated by the number of amplicon reads in each sample
