The ability of biology to change one molecule into another is astounding. Biochemical Engineering is the application of this process to the manufacturing of products on a large scale. Biochemical engineering is a field of chemical engineering that involves the application of engineering processes to biological organisms or systems such as bioreactors. Biochemical engineering is the use of biological (natural or organic) materials to generate products and processes, such as organisms, cells, and specific chemicals. Biochemical engineering is used in industries such as biotechnology, biofuels, medicines, water purification, and food. They employ biochemical engineering to create, test, and manufacture materials and products that enhance society or human well-being. The resulting goods are frequently made up of a mix of organic and lab-made elements.
