TAXONOMY: cellular organisms -> Bacteria -> Bacteroidetes/Chlorobi group -> Bacteroidetes -> Bacteroidia -> Bacteroidales -> Bacteroidaceae
The family 'Bacteroidaceae' is composed of five genera of environmental bacteria.Bergey's Manual of Systematic Bacteriology, 2nd ed., vol. 1 (The Archaea and the deeply branching and phototrophic Bacteria) (D.R. Boone and R.W. Castenholz, eds.), Springer- Verlag, New York (2001). pp. 465-466. The genus Capsularis used to exist prior to 1982, but its only species, B. zoogleoformans, was later deemed to be more closely related to the genus Bacteroides.
