What is microbiology?
In other words it is the study of all living organisms that are too small to be visible to the naked eye. The branches of microbiology can be classified into pure and applied sciences. It includes fundamental research on the biochemistry, physiology, cell biology, ecology, evolution and clinal aspects of micro organisms, including the host response to these agents. There is considerable overlap between the specific branches of microbiology with each other and with other disciplines.
Microorganisms and their activities are vitally important to virtually all processes on Earth. Microbes play key roles in nutrient cycling, biodegradation, climate change, food spoilage, the cause and control of diseases and biotechnology. Microbes can be put to work in many ways - making life saving drugs, manufacture of biofuels, cleaning up pollution, producing and processing food and drink.
Microbiology research has been central to meeting many of the current global aspirations and challenges such as maintaining food, water and energy security for a healthy population on a habitable Earth.
