In the cytoplasmic membranes of both bacteria three ferredoxin-like centres and a centre detected in the oxidized state (g = 2·015) were resolved. In addition, a Rieske-type iron-sulphur centre (g y = 1·90) was observed in P. cichorii but not in P. aptata. The absence of the Rieske centre in P. aptata parallels the absence of cytochromes c in this bacterium.", }
