Bacteria and molds are part of nature and are sometimes responsible for disease, spoilage of nutrients and drinking water, and corrosion; however, they are essential for keeping the ecosystem balance, to process nutrients, and for production of diverse industrial materials.

Aim of microbiologists:
  • reproducible growth of their microbial cultures (requires defined environmental conditions with respect to energy source, temperature, pH and nutrients)
  • reproducible and reliable tests to identify and differentiate microorganisms
  • reproducible reagents for science

  • detection, enumeration, differentiation and identification of organisms
  • biotechnology industry (fermentation of foods, pharmaceuticals etc.)
  • science (study single genes and their proteins, nature of organisms, etc.)
