    • author "Sasha"
    • tags "Mirco exam 2 "
    • description "Archaea and the Deeply Branching and Phototrophic Bacteria"
    • fileName "Vol 1 of Bergey's Manual"
    • freezingBlueDBID -1.0
    • Phylum Crenarchaeta
    • Strict anaerobic
    • Thermophilic
    • Many are acidophiles ans sulfur dependent.
    • Live in sulfur rich hot springs.
  1. Phylum Euryarchaeta
    Diverse organisms and habitats

    Includes methanogens, halobacteria, and thermoplasms.
  2. Methanogens
    • From Phylum Euryarchaeta
    • Strict anaerobes that produce methane.
    • From swamps, marshes, freshwater and marine sediments.
    • Rumen and intestinal system of animals.
  3. Halobacteria
    • From Phylum Euryarchaeta
    • Extreme haolophiles
    • Require @ least 1.5M NaCl for growth.
    • In the Great Salt Lake Dead Sea, and can cause spoilage in salted fish.
  4. Thermoplasms
    • Phylum Euryarchaeta
    • Lack cell walls.
    • Live in refuse piles of coal mines, geothermal soils and springs.
    • Optimum growth around 60 C and pH < 2
  5. Phylum Aquificae
    • -Represent the deepest or earliest branch of bacteria, hyperthermophile, and chemolithoautotrophs.
    • -Produces water by using hydrogen to reduce oxygen
    • -Gram negative and microaerophilic rod.
  6. Phylum Deinococcus Thermus
    • -Gram positive. -Aerobic and mesophilic.
    • -extraordinarily resistant to desiccation and gamma radiation.
  7. Phylum Chloroflexi
    • -Gram Negative
    • -has photo- and nonphotosynthetic members.
    • -Based on 16S rRNA this phylum doesn't appear closely related to any bacterial group and is deep & ancient branch of the bacterial tree.
    • - green nonsulfur bacteria carry out anoxygenic photosynthesis.
    • - required organic carbon sources.
  8. Phylum Cyanobacteria
    • - oxygenic photosynthetic bacteria
    • - Contain chlorophyll a
    • - unicellular or filamentous.
    • - branched or unbranched
    • - incorporate CO2 through the Calvin cycle
    • - Gram negative
  9. Phylum Chlorobi
    • - Known as the green sulfur bacteria
    • - use hydrogen sulfide as a source of electron INSTEAD of water.
    • - producing sulfur instead of O2
    • - leads to sulfur granules deposited outside of the cell.
    • - Gram Negative
    • - lives in anaerobic sulfide rich zones of lakes.
    • - uses the TCA cycle to produce CO2.
