Within this setting, in shallow coastal water conditions, consortia of bacteria set up microbial mat columns to exploit the supply of sulphate and nitrate from water. In the muds below the mats, methanogens were active, and above them methane-oxidizing bacteria. The waters were enriched chemically by contributions from hydro-thermal water plumes, either from the laterally equivalent beginnings of Reliance Fm volcanism elsewhere in the basin, or from more distant oceanic sources. Photosynthetic green sulphur bacteria may have oxidized H2S to S°, whereas sulphate and sulphur reducers operated in the reverse direction.

A small part of HjS in the biosphere remains in the form of insoluble sulphides or is spontaneously oxidized with oxygen to elementary sulphur. Photosynthetic and chemoautotrophic bacteria are capable of oxidizing HjS and elementary sulphur to sulphate. This biological oxidation is aflFected either aerobically (colourless sulphur bacteria) or anaerobically (photosynthetic purple and green sulphur bacteria). 

The photosystems of green plants and photosynthetic bacteria appear to function with basically the same sort of mechanisms of energy transfer, primary charge separation, electron transfer, charge stabilization, but the molecular constituents of the reaction center are quite diflFerent. Photosystem I contains iron-sulphur proteins as electron acceptors so can be called iron-sulphur (FeS) type reaction center, while photosystem II contains pheophytin as the primary electron acceptor and quinone as the secondary acceptors so it can be called pheophytin-quinone (4>-Q) type . The reaction center of purple bacteria, green nonsulphur bacteria, and PSII are (4>-Q) type. Green sulphur bacteria, heliobacteria, and PSI have (FeS) type reaction centers. ...
