Alpha Proteobacteria

The first class of Proteobacteria is the Alphaproteobacteria. The unifying characteristic of this class is that they are oligotrophs, organisms capable of living in low-nutrient environments such as deep oceanic sediments, glacial ice, or deep undersurface soil.

Among the Alphaproteobacteria are two taxa, chlamydias and rickettsias, that are obligate intracellular pathogens, meaning that part of their life cycle must occur inside other cells called host cells. When not growing inside a host cell, Chlamydia and Rickettsia are metabolically inactive outside of the host cell. They cannot synthesize their own adenosine triphosphate (ATP), and, therefore, rely on cells for their energy needs.

PARACOCCUS CAROTINIFACIENS

Class:	Alpha Proteobacteria
Genus:	Paracoccus
Species:	Paracoccus carotinifaciens
Description:	Paracoccus carotinifaciens, a new aerobic Gram-negative astaxanthin-producing bacterium .The strain E-396T, isolated from soil, was Gram-negative, aerobic, orangepigmented, rod-shaped, motile by peritrichous flagella and astaxanthin-producing. This organism produced carotenoids, mainly astaxanthin, and did not produce bacteriochlorophyll.
