What is microbiology?
Microbiology is the study of all living organisms that are too small to be visible with the naked eye.
This includes bacteria, archaea, viruses, fungi, prions, protozoa, and algae collectively known as microbes. This discipline includes fundamental research on the biochemistry, physiology, cell biology, ecology, evolution, and clinical aspects of microorganisms, including the host responses to these agents.
Microbes play a key role in nutrient cycling, biodegradation,climate change, food spoilage, the cause and control of diseases and biotechnology. They influence all living things and contribute to all manner of chemical and physical processes. As theses activities are so diverse, the science of microbiology is multidisciplinary. Virology, mycology, parasitology, and bacteriology are the various branches of microbiology.
Microbes are useful in making life saving drugs, manufacture of biofuels, cleaning up pollution and processing food and drink.
