Chromatiaceae

Colony of Thiocystis, copyright Patterson, David J.; Zettler Amaral, Linda; Edgcomb Virginia.

Belongs within: Chromatibacteria.

The Chromatiaceae are a group of anoxygenic phototrophic purple sulphur bacteria that, under the right growth conditions, deposit globules of elemental sulphur inside their cells (Imhoff 2001).

Characters (from Imhoff 2001): Photoautotrophic, anaerobic, using sulphide or elemental sulphur as an electron donor; major photosynthetic pigment bacteriochlorophyll a or b. Occasionally growing photoheterotrophically, chemoautotrophically or chemoheterotrophically. Usually possessing vesicular-type intracellular membranes; depositing globules of elemental sulphur inside cells. Flagella and/or gas vesicles may be present. Major type of cytochrome C c₅₅₁; major quinones MK-8/Q-8; major fatty acids C_16:0, C_16:1, C_18:1 (32–45%).
