Alpha Protobacteria
Definition
ex) Rhizobium live in the root nodules of legumes, converts N2 to proteins
Hypothesized that mitochondria evolved from aerobic alpha proteobacteria through endosymbiosis.
Term
Beta Proteobacteria
Definition
ex) Nitrosomanas, soil bacteria which recycle by oxidizing ammonium, producing nitrite as a waste product.
Term
Gamma Proteobacteria
Definition
ex) Thiomargarita namibiensis, obtains energy by oxidizing H2S producing sulfer as a waste product.
ex) E. Coli, a harmless symbiont used in experiments

Pathogens, autotrophic
Term
Delta Proteobacteria
Definition
Slime-secreting myxobacteria, which releases "myxospores" (subgroup)

Bdellovibrios. attacks other bacteria and bores into prey through sheer speed
Term
Epsilion Proteobacteria
Definition
Pathogens to humans and other animals.
ex)Campylobacter-blood poisoning and intestinal inflammation
Heliobacter pylori-stomach ulcers
Term
Cyanobacteria
Definition
only prokaryotes with plant-like, oxygen-generating photosynthesis. Chloroplast evolved from endosymbiotic Cyanobacterium. Abundant wherever there is water. Some specialized for nitrogen fixation.
Term
Coleoptera
Definition
Beetles, the most rich order of insects. Two pairs of wings, armored exoskeleton, mouthparts. Complete metamorphisis into adulthood.
Term
