Industrial ecology. Industrial ecology (IE) is the study of material and energy flows through industrial systems. The global industrial economy can be modelled as a network of industrial processes that extract resources from the Earth and transform those resources into commodities which can be bought and sold to meet the needs of humanity.
Industrial microbiology or microbial biotechnology is the application of scientific and engineering principles to the processing of materials by microorganisms (such as bacteria, fungi, algae, protozoa and viruses) or plant and animal cells to create useful products or processes. Vaccines. 2  Vaccines are essential to protect humans and animals from microbial diseases. 3  Recombinant DNA technology has allowed for the production of vaccines that offer protection without risk of infection (e.g. hepatitis B vaccine). 4  New vaccines are being developed by industrial microbiologists every day.
