Challenges In all bioprocesses: Improve the productivity Reduce the process cost

Processes in Biotechnology Genetically Engineering The breakthrough makes it possible to develop effective bioprocess to produce the products desired for our society.

Demands for Engineers Convert these visions of biologists to reality: Develop commercial bio-product to benefit our society. Biochemical Engineering with a potential to become one of the leading fields in chemical engineering.

Course Objectives To provide a general understanding of the basic concepts of - microbiology - biochemistry and genetics To apply chemical engineering principles to - bioreactor analysis - downstream processing and bioprocess optimization and control.

Introduction of Biochemical Engineering What is Biochemical Engineering?

Definitions Biochemical engineering: it has usually meant the extension of chemical engineering principles to systems using a biological catalyst to bring about desired chemical transformations.

Definitions Biotechnology - Traditionally, implies the use or development of methods of direct genetic manipulation for a socially desirable product. - Broadly, “Commercial techniques that use living organisms, or substances from those organism, to make or modify a product…” (Congress of the United States, 1984)

Definitions Fermentation -Traditionally, defined as the process for the production of alcohol or lactic acid from glucose. -Broadly, defined as “an enzymatically controlled transformation of organic compound” (Webster’s New College Dictionary)

Biochemical Engineering History 5000 to 10,000 BC: yogurt, cheese and soy products, wine and beer. In early 20th century: pure bakers yeast were being produced in tanks and sold. In world war I: fermentation was used to produce chemicals needed for war. World War II: antibiotics production became on the commercial scale. 1970s: recombinant DNA technology

Canadian Innovative Biotech Companies According to the survey of Statistics Canada every two year: 532 innovative biotechnology firms in Canada in % increase from 496 in Canada in % increase from 375 in % increase from 282 firms in 1997.

Regulation and organization In pharmaceutical and biotechnology industry, Primary concern: to produce a product of consistently high quality in amounts to satisfy the medical needs of the population. Secondary concern: to reduce the manufacturing cost. A future biochemical engineer needs to understand the regulatory climate in which many bioprocess engineers work. U.
