Growth and division in Bacteria and Archaea (Bacterial growth and…

- - - - depends on organism and on growth conditions (smaller bacteria grow faster due to more SA)
      - Cells HEALTHIEST produce virulence factors and metabolites
    - - Nutrients are USED UP
      - cell number STAYS STABLE (no or minimal growth)
    - - depends on history of culture and growth conditions (damaged or depleted?)
      - Adaptation to new conditions
    - - Waste products may kill cells or signal autolysis to DECREASE cell numbers and supply nutrients to those remaining
- - - - Facultative
        
        Grows better with O2, Aerobic respiration- anaerobic respiration and Fermentation = E COLI
      - Obligate
        
        requires O2 - Aerobic respiration
      - Microaerophilic
        
        Requires O2 but at levels lower than atm- aerobic respiration
    - - Aerotolerant
        
        does not require O2, grows better w/o it - fermentation
      - Obligate
        
        O2 harmful and lethal - fermentation or anaerobic respiration
