🧫 Environmental control of metabolism

Growing microorganisms has been a fundamental element of much of experimental biology, as well as the underpinning of many modern molecular biology techniques. Perhaps we have a sample of earth that we want to analyse to find a new microorganism with antibacterial properties. Perhaps we are testing a patient sample for an infectious agent. Most likely, we are culturing a safe strain of E. coli that has been genetically modified to produce a protein of interest like human insulin that we can isolate from it and administer to patients.


This is how the metabolism of microorganisms can be used to obtain specific biological products. Culturing them is the go-to method because they are very adaptable, easy to use and have fast growth. Therefore, a variety of environmental factors can be fine-tuned in the lab to obtain specific outcomes or products from various types of microorganisms including archaea, bacteria and eukaryotes.


Secondary metabolism of microorganisms represents the non-basic pathways in metabolism that may not be entirely necessary for…
