Phylogenetic tree highlighting the position of S. autotrophica OK10T relative to the type strains of the other species within the genus and the type strains of the other genera within the order Campylobacterales. The tree was inferred from 1,327 aligned characters [8,9] of the 16S rRNA gene sequence under the maximum likelihood criterion  and rooted in accordance with current taxonomy . The branches are scaled in terms of the expected number of substitutions per site. Numbers above branches are support values from 350 bootstrap replicates  if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD  are shown in blue, published genomes in bold [14,15], such as the recently published GEBA genomes from Sulfurospirillum deleyianum  and Arcobacter nitrofigilis .
