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.

ACETOBACTER PEROXYDANS

Class:	Alpha Proteobacteria
Genus:	Acetobacter
Species:	Acetobacter peroxydans
Description:	Acetobacter peroxydans,cells are rod-shaped, 2-3 ¼m long and about 0.5 ¼m in width. Many diplobacters, which are very motile during the first few minutes on the slide.Strictly aerobic. Temperature optimum is 20-25 °C. Grows readily on ethanol, lactate, or on yeast extract alone, but not on carbohydrates and derivatives. Unable to metabolize any sugars. Resting cells readily oxidize DL-lactate, pyruvate, ethanol, acetate, some Krebs cycle intermediates, and several alcohols. Cell-free extracts oxidize glucose-6-phosphate, 6-phophogluconate and ribose-5-phosphate in suitable conditions.
