Microorganisms and their activities are critical to almost all processes on Earth. Microorganisms are essential because they touch every aspect of our lives in, on, and around us.
Studying all living organisms that are too small to be seen with the naked eye is known as microbiology. Bacteria, archaea, viruses, fungi, prions, protozoa, and algae are all examples of microbes.’ These microbes are important in nutrient cycling, biodegradation/biodeterioration, climate change, food spoilage, disease causation and control, and biotechnology. Microbes can be used in various ways, including the production of life-saving drugs, the production of biofuels, the removal of pollution, and the production/processing of food and drink.
Famous microbiologists’ research has resulted in some of the most important discoveries that have underpinned modern society, such as Jenner and his smallpox vaccine, Fleming and the discovery of penicillin, Marshall and the identification of the link between Helicobacter pylori infection and stomach ulcers, and Zur Hausen, who identified the link between papillomavirus and cervical cancer.
Microbiology research has been and continues to be critical in meeting many of the world’s current aspirations and challenges, such as ensuring food, water, and energy security for a healthy population on a habitable planet. Microbiology research will also answer big questions like ‘how diverse is life on Earth?’ and ‘does life exist elsewhere in the Universe?’
