Principles of Downstream Techniques in Bioprocess

The course covers the fundamentals, and design concepts of various down stream purification steps (unit operations) involved in a biochemical process. Down stream process is required to take a crude product from a fermentor or a bioreactor and purify it to the desired level. Hence it may involve solids, liquid and gas processing.The course covers cell breakage and recovery of intracellular material, Isolation of solids, Product recovery, Product enrichment/purification, Product polishing and finishing. This course is suitable for students pursuing their biotechnology, bioprocess engineering or other allied fieldThis course is also suitable for chemical engineers who would like to learn about separation techniques in biotechnology industries. The course will consist of lectures and solving problems. Problems will relate to design, estimating operating conditions and optimization of the process.
