Biochemical Engineering
Biochemical engineering, also known as bioprocess engineering, is a discipline that integrates principles of chemical engineering and biological engineering to develop processes that involve biological organisms or organic molecules. This field plays a crucial role in industries such as pharmaceuticals, biofuels, food production, biotechnology, and water treatment.
Historical Development
The roots of biochemical engineering can be traced back to the late 19th and early 20th centuries. A significant milestone was the discovery of pasteurization by Louis Pasteur, which is still a fundamental process in food safety. The field gained significant recognition when Alexander Fleming discovered penicillin in 1928, stimulating the development of industrial-scale fermentation processes.
Core Concepts
Biological Systems and Processes
Central to biochemical engineering is the manipulation of biological systems to produce desired products. This involves understanding and applying techniques from areas like biochemistry and microbiology to optimize the growth and productivity of microorganisms in bioreactors.
Bioreactors
Bioreactors are vessels or devices that create controlled environments for biological reactions. These systems are critical in scaling up laboratory findings to industrial production levels, ensuring that processes are efficient, safe, and economically viable.
Applications
Pharmaceuticals and Biotechnology
Biochemical engineering is pivotal in the production of pharmaceuticals, where it is used to synthesize drugs and vaccines. This includes the development of antibiotics and other therapeutic proteins.
Biofuels
The production of biofuels, such as ethanol and biodiesel, from renewable resources is another major application. Biochemical engineers work on optimizing the conversion of biomass into fuel, contributing to sustainable energy solutions.
Food and Beverage
In the food and beverage industry, biochemical engineering plays a role in processes like fermentation, used in the production of beer, wine, and yogurt.
Related Disciplines
Biochemical engineering intersects with various other engineering fields, such as:
