Phylogentic tree. Phylogenetic tree highlighting the relationship of Syntrophaceticus schinkii Sp3 relative to known SAOB, acetogens, and other syntrophic operating bacteria. The 16S rRNA-based alignment was carried out using MUSCLE [32] and the phylogenetic tree was inferred from 1,521 aligned characteristics of the 16S rRNA gene sequence using the maximum-likelihood (ML) algorithm [33] with MEGA 6.06 [34, 35]. Bootstrap analysis [36] with 100 replicates was performed to assess the support of the clusters
