Phylogenetic tree constructed using MEGA 7 [20] showing the current position of the A. acetethylicum strain GluBS11^T with respect to the selected members from the order Clostridiales. The evolutionary distances were computed using the Jukes-Cantor method [22] and are in the units of the number of base substitutions per site. The phylogenetic tree was searched using the Close-Neighbor-Interchange algorithm [59] at a search level of 1. All positions containing gaps and missing data were eliminated. There were a total of 1,300 positions in the final dataset. Numbers at the nodes indicates the bootstrap values from 1000 replicates [60] and accession numbers are given in parentheses. Bar indicates 2% estimated sequence divergence
