Abstract

Within the filamentous sulfur bacteria there are giant forms with cell diameters of up to several hundred microns. Members of this monophyletic group of bacteria possess a central vacuole, which restricts the active cytoplasm to a thin outer layer. Most of these sulfur bacteria seem to store nitrate in the vacuole, which they use as an electron acceptor for the oxidation of sulfide.
