“A cell of a higher organism contains a thousand different substances, arranged in a complex system. This great organized system was not discovered by chemical or physical methods; they are inadequate to its refinement and delicacy and complexity.” ~Herbert Spencer Jennings A biochemical engineer develops most of the products that people come into contact with on daily basis such as agricultural chemicals, paints, oil, plastic, soaps, paper, cosmetics, medicines etc. Biochemical engineering is a branch of chemical engineering which applies technological advancements to biological materials. Biochemical engineers combine knowledge of biology, chemistry and engineering to create products from raw materials and develop the processes for achieving this. It involves all the designing and engineering aspects related to production of useful products from microorganisms and deal with reactor designing and process designing. Biochemical engineers also deal with biotechnology like genetic engineering for medical, agricultural or industrial purposes.
