Phylogenetic analysis of selected representatives from the genus Nitrospira. A 16S rRNA gene-based maximum likelihood tree is shown. Sequences of cultured representatives are printed in bold, “N. lenta” in red. The tree was constructed using sequences ≥1165 bp and a 50% conservation filter, resulting in 1463 valid alignment positions. Leptospirillum ferriphilum (AF356829) and L. ferrooxidans (X86776) were used as outgroup, which is indicated by the arrow. Scale bar indicates 1% estimated sequence divergence
