Hence, he inferred that the O 2 evolved by the green plant comes from H 2 O, not from carbon dioxide. This was later proved by using radioisotopic techniques. The correct equation, that would Anoxygenic phototrophs such as purple and green sulphur bacteria play key roles in the sulphur cycle of anoxic habitats by coupling sulphur oxidation to autotrophic growth (Zerkle et al., ).

Today, bacteria are considered as one of the oldest forms of life on earth. Even though most bacteria make us ill, they have a long-term mutual Sulphur bacteria book with humans and are very much important for our survival.

Chapter aquatic organisms defines the place occupied within the bacterial kingdom by the micro-organisms that are responsible for these transformations. The hydrogen sulphide, anaerobic fermentation process converts organic sulphur compounds into H 2 S while other, aerobic, bacteria can oxidise H 2 S to form colloidal sulphur and /natural-water/sulphur-cycle.

Mats of colourless sulphur bacteria from a relatively exposed shallow water sediment and from a deeper, more protected sediment were studied.

EXERCISE 7 The Prokaryotes Organisms like bacteria, methanogens, and blue-green algae have cells lacking the membrane-bound nucleus found in protozoans, plants, and animals. Instead their single, circular DNA strand is often concentrated in an unbound nuclear region, called a nucleoid.
