History & Evolution
Louis Pasteur is credited with establishing industrial microbiology through his work on fermentation, which is where biochemical engineering got its start. The need for large-scale biological production techniques was later heightened by Alexander Fleming’s discovery of penicillin.
Bioprocess engineering was incorporated into chemical process engineering over time, enabling industries to increase production of biodegradable plastics and insulin, among other products. Modern biology and high-efficiency process design meet at the nexus of biochemical engineering.
Key Responsibilities & Roles
A biochemical engineer’s main responsibility is to translate biological research into industrial processes that are scalable, efficient, and financially viable. Designing a bioreactor, optimizing fermentation processes, upholding quality control, and resolving production issues are all part of this.
Many professionals who started out as chemical process engineers eventually transition into biochemical roles as they gain experience with bio-based systems. Furthermore, there is a lot of overlap with environmental chemical engineering, especially when it comes to applications like wastewater treatment and bioremediation.
Industries & Applications
Applications for biochemical engineering are numerous and span several rapidly expanding industries:
- Pharmaceuticals: Using sophisticated bioreactors and purification systems, biochemical engineers play a key role in the development and scaling of processes for vaccines, antibiotics, and monoclonal antibodies.
- Food & Beverage: Engineers contribute to increased efficiency and safety in the food industry by producing enzymes for processed foods and fermenting dairy products.
- Environmental Solutions: The principles of environmental chemical engineering are frequently applied in the treatment of industrial waste, pollution control, and bioremediation projects.
Biochemical engineers are also helping to produce biofuels, biodegradable packaging, and renewable raw materials as climate change and sustainability become major concerns.
