Growth Microorganisms Conditions Cheap Describe Reasons Biotechnological Processes

Microorganisms are useful in biotechnology due to simple growth requirements, a wide range of species for diverse chemical reactions, ease of genetic modification, rapid growth rates, simple and inexpensive nutrient needs, and low-condition cultivation, making bioprocesses cost-effective.

Mikroorganismid on biotehnoloogias kasulikud tänu probleemivabale kasvatusele, suurele liigirikkusele, geneetilise muundamise lihtsusele, kiirele kasvule ja arengule, lihtsatele ja odavatele toitainetevajadustele ning madalatele kasvutingimustele, mis muudavad bioprotsessid odavaks.

Front Describe the reasons why microorganisms are so useful for biotechnological processes.
Back Usefulness of microorganisms:
  • No welfare issues to consider - only need optimum growth conditions
  • Big range of microorganisms capable of carrying out many different chemical syntheses/degradations
  • Genetic engineering can be done easily to carry out unnatural synthesis reactions
  • Short life cycle and rapid growth rate - lots can be produced quickly
  • Nutrient requirements are often simple and cheap, can modify them to use materials that would otherewise be wasted
  • Conditions for growth are relatively low temp, oxygen, food and removal of waste gases (they have their own catalysts) - bioprocesses are cheap
