Maximum-likelihood phylogenetic tree illustrating the relationships of selected 16S rRNA Deltaproteobacterial sequences recovered from Middle Valley sediments to Deltaproteobacterial sequences and uncultured environmental phylotypes from NCBI non-redundant database. Representative sequences from Middle Valley sediments incubated in batch reactors at 55°C with ethane (Ethane55-MV), propane (Propane55-MV), and butane (Butane55-MV) in bold. The most closely related environmental phylotypes from Guaymas Basin sediment sequences have been marked (). The tree was rooted to Archaeoglobus profundus DSM 5631(NR_074522). Scale = 0.01 substitutions per site.
