Document Summary
Bacteria - >80 phyla are known (half have no representatives in culture), 90% of all characterized strains are in 4 phyla (proteobacteria, bacteroidetes, actinobacteria, Mycoplasmas: highly metabolically diverse groups that are mostly found in soils. Q: please explain why phototrophy is found only in a few strains (not all) of alpha-, It is likely that genes encoding for phototrophy were horizontally transferred to only few representatives of these classes of the proteobacteria. Archaea - 5 phyla (euryarchaeota, nanoarchaeota, korarchaeota, crenarchaeota, Thaumarchaeota); metabolically and functionally diverse, most are extremophiles (only. 570 nm: pmf is formed and drives. Atp synthesis: bacterial proteorhodopsin, crenarchaeota, most extreme hyperthermophiles that are from volcanic deep-sea environments, live at extreme temperatures (>100 o c and < -10 o c) Isolates mostly from geothermally heated environments (solfataras, heated industrial effluents, deep-sea hydrothermal vents: chemoorganotrophs and lithotrophs, anaerobic (no 3 , example: extreme thermophiles.
