Microbiologists investigate the growth, structure, development, and other characteristics of microscopic organisms, such as bacteria, algae, or fungi. Microbiologists work in a wide variety of settings, although the majority of work is laboratory-based. Microbiologists isolate and make cultures of microorganisms, identify their characteristics, and observe their reactions to chemicals and other kinds of stimuli. They also study how microorganisms develop and reproduce as well as their distribution in nature. Many microbiologists work for universities, where they teach and do research. Others work at medical centres or in private industry. Some work for government agencies. Although their jobs have different aspects and responsibilities, most microbiologists do some research or laboratory work. They use special equipment to study microorganisms including light microscopes, electron microscopes, centrifuges, glass tubes, slides, and computers. Biotechnologists use living cells, the products of cells, and micro-organisms to make a variety of products and processes that benefit people.
