Microorganisms are found everywhere – from icy Antarctica to the volcanic pipes on the bottom of the ocean where temperatures reach 268 centigrade.
These organisms are so small that they are usually invisible to the unassisted human eye. Microorganisms usually occur in large numbers and play a very important role in the biological activities in our environment as they interact with human beings, plants and animals.
Microbiologist’s findings are critical to research and application in health, industrial, agricultural and environmental sciences. They combine the techniques of genetics, chemistry, biochemistry, physiology, physics, ecology and pathology in order to find solutions to fresh water pollution, industrial processes which use micro-organisms to manufacture chemicals and controlling unwanted microbic activities which cause fuel to degrade and iron corrosion.
If you prefer working in the medical field, you’ll be responsible for developing effective vaccines and methods of preventing epidemics of dangerous diseases. (Did you know micro-organisms are used in the commercial production of antibiotics?)
Quite a responsibility! If you think you’re the man/women for the job you need to have an interest in the biological sciences and submicroscopic world and be very methodical and precise.
