Industrial microbiologists use microscopic organisms to create marketable products such as cleaning agents, antibiotics, and food products. They work in various industries, including waste management, breweries, bakeries, and pharmaceuticals, and are responsible for research, product testing, quality control, product development, and genetic engineering. A post-secondary degree in microbiology, biology, or biochemistry is required for this career.
An industrial microbiologist, sometimes called a biotechnologist, uses microscopic organisms in the production and manufacture of marketable products for commercial use. This position is used in the creation of many common household items such as cleaning agents, antibiotics, and food products. Job requirements vary by hiring industry and may require employees to conduct research and develop new products using microbial engineering. Microbiologists are employed by all aspects of the food industry, pharmaceutical companies and waste treatment systems.
Organisms commonly used in this type of fabrication are fungi, viruses, protozoa, bacteria, and algae. These microbes can be used to break down larger organic materials and synthesize new compounds through their natural ability to initiate new chemical reactions in the materials they interact with. An industrial microbiologist is trained to design these reactions in a controlled environment for different purposes. He may also be concerned with protecting products from invasion by these organisms. For example, antibacterial products and preservatives are designed to prevent bacteria from growing on surfaces and in some foods.
Industries that employ an industrial microbiologist include waste management, breweries, bakeries, and pharmaceuticals, among others. Algae and bacteria naturally feed on organic excrement and are often introduced into waste treatment plants to clean the water and break down large amounts of waste. Yeast is the microscopic life form responsible for the fermentation process that creates beer’s alcohol content and much of its flavor. This household organism is also the reason why bread, rolls and dough rise when allowed to sit and heat. Different types of antibiotics are created through the fermentation process of microorganisms known as actinomycetes.
These biotechnologists are instrumental in the production of most vaccines. A vaccine is usually created by isolating certain pieces of viral DNA and injecting them into a healthy individual. The body’s immune system analyzes the foreign DNA and starts making antibodies that will destroy it. When the vaccinated patient finally encounters the complete form of the virus, through potential exposure to an infected person, his body is already prepared to fight the disease. For example, the viral strain of influenza changes seasonally and a new vaccine must be created regularly to combat each new strain as it infects the general population.
An industrial microbiologist may be responsible for research, product testing, quality control, product development, and genetic engineering. This career path requires completion of a post-secondary degree with classes focused on biology, microbiology and biochemistry. Some internships also require applicants to also hold a master’s degree in microbiology, although this is not an industry standard.
