Microbiologist Career Description
Microbiologists study the anatomy, genetics and physiology of microorganisms, such as bacteria, fungi and viruses, as well as the vital interactions between microorganisms and the environment. Microbiologists apply this knowledge to manipulate selected micro-organisms both ecologically and industrially, to improve human beings' quality of life and to diagnose and control microbes that infect humans, animals, food and plants.
What am I going to do in this occupation?
Micro-organisms are found everywhere, from icy Antarctica, to volcanic pipes on the bottom of the ocean where temperatures reach 268 centigrade, in salt pans in arid Namibia, the bloodstream of animals and swamps, where the only source of food is carbon dioxide.
These organisms are so small that they are usually invisible to the unassisted human eye. But they occur in vast numbers and playa very important role in biological activities in our environment as they interact with human beings, plants and animals, either detrimentally or beneficially.
Microbiologists are involved in a wide variety of activities. These include finding solutions for fresh water pollution, identifying pathogenic micro-organisms, preventing food decay, facilitating microbiological processes in industries where micro-organisms are used in the manufacture of chemicals, and the control of unwanted microbic activities which cause losses, for example degrading aviation fuel, corroding iron tubing and breaking down textile products.
In the medical world microbiologists are responsible for the fast and accurate location and identification of pathogenic and toxic micro-organisms. They develop effective vaccines and methods of preventing epidemics of dangerous diseases. Micro-organisms are used in the commercial production of antibiotics.
Requirements
What kind of personality do I need? Besides having an interest in the biological sciences and submicroscopic world, prospective microbiologists must be methodical and precise and enjoy doing laboratory work. The ability to work independently is also important.
Where can I work?
Microbiologists are employed by several institutions, such as in the baking, dairy, wine, beer and sorghum industries, fermentation industries and research institutions.
Can I work for myself in this occupation?
There are some opportunities for self-employment in research and the private sector, for example as private consultants.
