Description and Significance
Blastochloris virdis is a purple non-sulfur beta proteobacteria. The proteobacteria are a large, metabolically diverse bacterial phyla consisting of gram-negative organisms. [3] It is both a heterotroph and a photoheterotroph. It absorbs light around the wavelength of 400 nm and 1,000nm, resulting in its purple color. It has one of the simplest photosynthetic systems, composed of just one light-harvesting complex surrounding the reaction center. [2] The light-harvesting complex is photosytem II. [3] Its simplicity has lead to its usage in the study of plant biochemistry and pathways.
Structure, Metabolism, and Life Cycle
Interesting features of its structure; how it gains energy (how it replicates, if virus); what important molecules it produces (if any), does it have an interesting life cycle?
Ecology and Pathogenesis
Natural habitat (soil, water, commensal of humans or animals?)
If relevant, how does this organism cause disease? Human, animal, or plant hosts? Important virulence factors, as well as patient symptoms.
