Microbial Cell Growth
  • Mode of Growth
  • Selective assimilation of nutrients and convert
    into and also include Chemical rearrangement of
    protoplasmic material characteristic of the
    particular organism
  • Production of an increased amount of nuclear
    substance and cell division

Growth Phase
  • Induction Phase (Lag Phase)
  • Transient Phase (Acceleration Phase)
  • Exponential Phase
  • Stationary Phase (Declining Phase)
  • Death Phase

Question Sheet
  • Why microbial growth have an lag phase?
  • Why death phase could be occurred in microbial
    growth?
  • What is essential nutrient for growth of organism
    especially prokaryotes?
  • What is important factor for cell division?

    temperature?
  • Which empirical equation that you choose of
    inoculation of microorganism in case of multiple
    content limitation of nutrients, such as Mg2,
    phosphate, Nitrate and organic compound?

Question Sheet
  • What is happen if microorganism is at 90oC? Why?
  • In case of decreasing of temperature about 20oC
    from optimum temperature, what is happen in case
    of microbial growth rate?
  • In case of ethanol production that was S. sake
    have ethanol tolerance around 10, what do you do
    to make an whisky industry?
  • Why a shade microbe does not grew well in high
    light illumination and commonly have not high
    temperature resistance?
