The Microbial World

Chapters 5, 15

plankton classification
Plankton Classification
  • Megaplankton 20-200 cm
  • Macroplankton 2-20 cm
  • Mesoplankton 0.2-20 mm
  • Microplankton 20-200 μm
  • Nanoplankton 2-20 μm
  • Picoplankton 0.2-2 μm
metabolism
Metabolism
  • Metabolism- all chemical reactions that occur in an organism.
  • Autotrophic- requiring carbon dioxide and a source of energy for the synthesis of organic molecules (glucose).
    • Photoautotrophs- absorb light energy from the sun.
    • Chemoautotrophs- derive energy from chemical compounds.
  • Heterotrophic- requiring complex organic compounds; obtains energy by consuming organic matter.
photosynthetic prokaryotes
Photosynthetic Prokaryotes
  • Kingdom- Bacteria
    • Phylum- Cyanophyta
cyanophyta
Cyanophyta
  • Characteristics
  • Examples- Oscillatoria, Synechococcus, Synechocystis.
cyanophyta gram negative bacteria
Cyanophyta- Gram Negative Bacteria
  • Gram positive- peptidoglycan layer; stains with crystal violet.
  • Gram negative- peptidoglycan layer sandwiched by lipopolysaccharide and protein layers; does not stain with crystal violet.
global o 2 from photosynthesis
Global O2 from photosynthesis
  • 80% comes from marine cyanobacteria.
    • Synechococcus
    • Synechocystis
  • 20% comes from terrestrial systems.
    • 5% of this comes from tropical rainforests.
archaea
Archaea
  • Prokaryotic
  • Extremophiles
    • Hydrothermal vents
    • Hypersaline basins
    • Highly acidic env.
