Aspects Of Biochemical Engineering

By Prof. Debabrata Das   |   IIT Kharagpur
Learners enrolled: 852
Biochemical Reaction Engineering is mostly deals with the most complicated life systems as compared to Chemical Reaction Engineering. To describe the behavior of any life system in terms of mathematical form is the basic essence of biochemical reaction engineering. The present course in true sense is an interdisciplinary subject since biologist, physicist, chemist, technologist and mathematician all join hand in hand to develop realistic models. This specialized subject comprises of transport processes, sophisticated advanced control system besides conventional biology, physics and mathematics. Production of biomolecules can be done broadly in two different ways namely, using enzymes and microbial cells. The present course is designed to cater all the above aspects of the subject. Students undergoing this course will be initially able to differentiate between conventional chemical reaction engineering and biochemical reaction engineering. They also develop the expertise to do the design of any biochemical process which will be very much useful for the industries.
