The bacteria involved include Azotobacter, Clostridium, Chromatium
and Chlorobium (Burris 2002).
These were assigned as 1 CO and 2 [CN.sup.-] for Dg enzyme, (74) as well as for similar [NiFe]-enzyme from Chromatium vinosum, (84) whereas the electron density of one of three ligands (L1 of Fig.

El sistema genetico tipo III, se encuentra en Chromatium
vinosum, Synechocystis sp.
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.).
Despite the abundance of the isolates in the samples, Serratia marcescens, Escherichia coli, Enterobacter aerogenes, Chromatium
sp, and Erwinia amylovora exhibited minimal growth towards the end of incubation period indicating weak ability to utilize the PAH.
Light levels as low as 1% of the incident near-infrared radiation (800 to 900 nm) are sufficient for Chromatium
, a phototrophic purple sulfur bacterium, to dominate the chemocline (Fig.
Below Microcoleus are the red and green sulphur bacteria, including salmon-colored colonies of Thiocapsa, pink swimming Chromatium
, and the strictly anaerobic green Chlorobium.
Lipases provide a new mechanistic model for polyhydroxybutyrate (PHB) synthases: characterization of the functional residues in Chromatium
vinosum PHB synthase.
