Importance

• Bio 101 lab
• Rhoads

2
Know your kingdoms

• Plants
• Animals
• Fungi molds yeast mushrooms
• Protista protozoa algae diatoms
• Prokaryotes bacteria archae cyanobacteria
• Microbial kingdoms fungi, protista,
  prokaryotes

3
Prokaryotes Bacteria

• 1 claim to fame metabolic diversity
• Disease most pathogens are bacteria 109
  deaths
• Disease prevention competition! antibiotics
  vaccines
• Ecology? Primary degraders in the nutrient
  cycle

4
Bacteria continued

• Food Good preservation via fermentation
  ex. lactic acid in dairy
  products
• Bad food spoilage food poisoning
  ex. Staphylococcus aureus E. coli
  botulism
• Agriculture Good 1. N fixation N2 ? NO3
  root nodules 2. BT cotton makes its own
  insecticide!
• Bad Denitrification NO3 ? NH3

5
Bacteria continued

• Bioremediation using microbes to remediate
  problems How? 1. catabolize organics 2.
  change solubility of metals

6
Prokaryotes wrap-up

• Cyanobacteria oxygenic non-cyclic
  photosynthesis oxygen autotrophy
  .but not always wanted
• Archae genetically archaeic extreme
  environments

7
Protista

• Protozoa Wall-less, animal-like eukaryotic
  microbes
• Ecology secondary degraders in nutrient cycle
  Disease malaria PCP Toxoplasma
  enteric bugs
• Algae Plant-like eukaryotic microbes
• Ecology ONP oxygen autotrophy
• some are single-celled
• some are multi-cellular
• and then there are diatoms
  encased in glass

Diatoms
9
Fungi

• Molds heterotrophs filamentous
• Ecology 1 saprophytes decompose
  recalcitrant O.C. Disease PCP Crypto
  meningitis plants!!!
• Yeast fermenters single-celled fungi
• Ecology? Food fermentation
  acid alcohol CO2 Disease Candida
  albicans
