Exploring the intersection of chemistry, biology, and engineering, Biochemical engineering & metabolic engineering focuses on transforming biological systems into efficient production platforms. Biochemical engineering optimizes cell culture techniques, bioreactor operations, and downstream purification processes. At the same time, metabolic engineering reconstructs cellular pathways to enhance the synthesis of desired products such as amino acids, biofuels, or antibiotics. Researchers are now employing computational models and CRISPR-based genome editing to predict and fine-tune metabolic fluxes. This integrated approach allows for dynamic control over microbial and mammalian systems, improving yields and reducing waste. Biochemical Engineering & Metabolic Engineering continues to drive progress in synthetic biology, bioenergy, and therapeutic development, bridging lab-scale discoveries with commercial-scale operations across biotechnology sectors.
