Phylogeny of Ca. Chlorobium antarcticum from the Vestfold Hills. Maximum-likelihood trees for a 16S rRNA gene and b FmoA protein sequences of members of the Chlorobiaceae family. The phylogenetic trees were prepared with MEGA X v10.1.7 using 1,000 bootstrap values. Trees are drawn to scale, and branch-length scale bars are provided in each panel. Numbers next to branches represent bootstrap values showing the percentage of trees in which the taxa clustered together. Only bootstrap values greater than 50% are shown. Ca. Chlorobium antarcticum from the Vestfold Hills systems, AL, EF, and TB, are highlighted
