Largest and most metabolically diverse
Purple Sulfur Bacteria Use Hydrogen sulfide α, β, γ subdivisions
Purple Nonsulfur Bacteria Photoheterotrophy Aerobic respiration
Nitrifying bacteria Chemolithotrophs Nitrosomonas, Nitrobacter
Sulfur Oxidizing Bacteria Thiobacillus, Beggiatoa Sulfuric acid produced
Methanotrophs Anaerobic Archaea –not bacteria
Aerobic Chemoorganotrophs Pseudomonas and pseudomonads
Pseudomonads Common genera: Pseudomonas, Xanthomonas, Burkholderia, Gluconobacter Metabolically diverse -100 substrates Plant and human pathogens Fluorescent - burn patients Burkholderia - ganders Xanthomonas – soft root vegetables Zymomonas Ferments Alcohol production in the tropic
Acetic Acid Bacteria Acetobacter, Gluconobacter Alcohol → Acetic acid and Cellulose?
Nitrogen Fixing Bacteria Azotobacter, Beijerinckia Nitrogenase is oxygen sensitive Cysts, capsule, and poly-β-hydroxybuytrate
Neisseria and Relatives Neisseria, Acinetobacter, Chromobacterium, Moraxella Some human pathogens Most oxidase positive
Enteric Bacteria Escherichia, Salmonella, Proteus, Enterobacter Facultative anaerobes, peritrichous flagella, Gut flora, human pathogens
Escherichia Universal inhabitant of warm blooded animals Vitamin synthesis Rarely pathogenic Salmonella and Shigella Usually pathogenic Salmonella found in some cold blood animals
Proteus swarming Butandiol fermenters Enterobacter, Klebsiella, Serratia
Vibrio and Photobacterium Oxidase positive Polar flagella Fermentative Aquatic Bioluminescent
Rickettsia Small intracellular parasites Human diseases Arthropod vectors
