biotechnology: industrial applications of biological processes

industrial fermentation is used widely to cultivate bacterial and fungal cells

advantages to using microorgansism in fermentaion:

  • microorgansism grow rapidly and enzymes don't need to be supplied
    • so fermentation can occur at lower temperatures
      • so it is cheaper

Fermenter Design:

  • pure culture us needed for the formation and harvesting of a pure product
  • organsims needs suitable conditions for growth without competition for maximum efficiency
  • vessel sterilised before hand and sterile medium needed
  • vessel openings proteced from contamination by filters
  • asceptic conditions and handling maintain purity
  • forced aeration fro maximum growth or aerfobes and mix the culture to improve contact with nutrients
    • may…
