Green non sulphur bacteria
WebProcedure Procedure: (work in pairs) Collect 1 GSA plate, 1 TSA plate, and 1 EMB plate. Organisms that you will be working with: Escherichia coli (G-) Staphylococcus epidermidis (G+) Pseudomonas aeruginosa (G-) Enterobacter aerogenes (G-) 1. With a marker, divide the bottom of all three Petri plates into quadrants. WebExamples include green sulphur bacteria, purple sulphur bacteria, purple non-sulphur bacteria, phototrophic acidobacteria and heliobacteria, FAPs (filamentous anoxygenic phototrophs). CO 2 + 2H 2 A + light energy → [CH 2 O] + 2A + H 2 O ; where H 2 A can be any electron donor, e.g. H 2 S, H 2 etc.

For this reason, they use sulfur (or other forms of sulfur-like elemental sulfur or thiosulfate) instead of water as the electron donor (splitting water releases oxygen).
WebWithin the prokaryotic domain, there are five main groups of bacteria that perform tetrapyrrole-based photosynthesis. They are proteobacteria (also known as purple bacteria), heliobacteria, Chloroflexi (filamentous bacteria also known as green non-sulfur bacteria), Chlorobi (green sulfur bacteria) and cyanobacteria.
WebGreen sulfur bacteria generally do not move (non-motile), and can come in multiple shapes such as spheres, rods, and spirals.
