Universal Ancestor Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes Helical heterotrophs to 0.25 mm long but very thin! Rotational bacterial filament Free-living and pathogens: Treponema pallidum = syphilis Borrelia burgdorferi = Lyme disease Universal Ancestor Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes Gram Positive: very diverse Actinomycetes: branched chains tuberculosis, leprosy Soil: Streptomyces antibiotics Solitary: Bacillus, Clostridium anthrax, botulism Staphylococcus: clusters Streptococcus: chains “hospital diseases” Mycoplasmas 0.1m walking pneumonia Universal Ancestor Domain Prokarya Kingdom Bacteria Proteobacteria Chlamydias Spirochetes Gram Positive Cyanobacteria likely source of chloroplast by endosymbiosis unicell, colony, filament photoautotrophs: CO2 + H2O O2 + CH2O heterocysts: N2 fixation Universal Ancestor N2 + H+ + ATP NH4+
