An industrial microbiologist, also known as a biotechnologist, uses microscopic organisms in the production and manufacture of commercially viable products. Many common household items, such as cleaning agents, antibiotics, and food products, are made in this position. Employees may be required to conduct research and develop new products using microbial engineering, depending on the hiring industry. Microbiologists work in the food industry, pharmaceutical companies, and waste treatment systems, among other places.
Fungi, viruses, protozoa, bacteria, and algae are commonly used in this type of manufacturing. Because of their natural ability to initiate new chemical reactions in the materials with which they interact, these microbes could be used to break down larger organic materials and synthesize new compounds. For various purposes, an industrial microbiologist is trained to engineer these reactions in a controlled environment. He might also be concerned about preventing these organisms from invading products. Antibacterial products and preservatives, for example, are designed to prevent bacteria from growing on surfaces and in some foods.
Waste management, breweries, bakeries, and pharmaceuticals are among the industries that employ an industrial microbiologist. Algae and bacteria feed on organic waste naturally, and they’re frequently used in waste treatment plants to clean the water and break down larger amounts of waste. The microscopic life form responsible for the fermentation process that gives beer its alcoholic content and much of its flavor is yeast. When bread, rolls, and dough are allowed to sit and warm, this household organism causes them to rise. Actinomycetes, a type of microorganism, produce a variety of antibiotics through a fermentation process.
Most vaccines require the expertise of these biotechnologists. In most cases, a vaccine is made by isolating specific portions of viral DNA and injecting them into a healthy person. The immune system of the body analyzes the foreign DNA and produces antibodies to destroy it. When a vaccinated patient is exposed to the full form of the virus, such as through contact with an infected person, his body is already equipped to fight the infection. For example, influenza virus strains change seasonally, necessitating the development of a new vaccine to combat each new strain as it infects the general public.
Research, product testing, quality control, product development, and genetic engineering may all fall under the purview of an industrial microbiologist. This profession necessitates the completion of a post-secondary degree that includes biology, microbiology, and biochemistry courses. Some job openings also require applicants to have a master’s degree in microbiology, though this is not a requirement in the industry.
