The bacteria involved include Azotobacter, Clostridium, Chromatium and
Chlorobium (Burris 2002).

The second column represents a lake of the Archaean Eon (3500 million years ago) and holds an anaerobic community predominated by purple sulfur phototrophic bacteria (Chromatium sp., Thiocapsa sp.) and green sulfur bacteria (
Chlorobium sp.).
In our previous work, we had data-mined genomic databases and utilized available biochemical data on metabolic pathways of several reductive chemoautotrophic organisms that included Aquifex aeolicus, Hydrogenobacter ther-mophilus, Thiomicrospira denitrificans, and
Chlorobium terpidium, enabling us to construct an almost complete chart of reductive autotrophic intermediary metabolism (Sriniva-san and Morowitz, 2009).
Below Microcoleus are the red and green sulphur bacteria, including salmon-colored colonies of Thiocapsa, pink swimming Chromatium, and the strictly anaerobic green
Chlorobium.

Chlorobium thiosulfatophilum, Proprionibacterium shermanii, E.
The nature of this early life was unclear until studies beginning in 1966 on the bacterium
Chlorobium limicola forma thiosulphatophilum led to the discovery of a metabolic network that has come to be known as the reductive citric acid (rTCA) cycle (Evans et al., 1966).
