  • a Taxa refer to named species and to phylotypes with or without cultivable members. Phylotypes are defined as clusters whose members have 98.5% full 16S rRNA sequence similarity. The data in this table are based on those in HOMD version 10.

  • b Named species are those with validly published names.

  • c Unnamed cultivable taxa are phylotypes that have at least one extant isolate.

  • d Uncultivated taxa are phylotypes known only from clone sequences.
