  1. Engineering Biology CHEE 450 Prof. Ron Neufeld Biosciences 1443, 533-2827 ron.neufeld@chee.queensu.ca

  2. Acknowledgments Many images in this course originate from the web. The source may be determined by placing your cursor over the image. In a few cases, images were scanned from textbooks or literature journals. The source of any image may be obtained by contacting ron.neufeld@chee.queensu.ca. A few of the images actually belong to the instructor. Example of image belonging to instructor Nantes, France (La Cigale)

  3. Office hours and location • 7:48 am to 5:39 pm, Monday to Friday if I am there • e-mail any time – response usually same day • office in Biosciences 1443, near Tim Horton’s (instructor likes it black, no sugar with raisin bran muffin)

  4. Course web page • reminders • course outlines (and notes) • assignments (and solutions) • test and exam dates • grad club class meeting dates • items in the news

  5. Course objectives • Biochemical Engineering is the application of Chemical Engineering principles and approaches to biologically-based systems and processes • Engineering Biology will examine the underlying biological and biochemical principles

  6. Course text The Official Rock Paper Scissors Strategy Guide by Graham Walker and Douglas Walker $8.96 on Amazon.com

  7. Reference material • Shuler and Kargi, Bioprocess Engineering: Basic Concepts • Blanch and Clark, Biochemical Engineering • Bailey and Ollis, Biochemical Engineering Fundamentals

  8. More reference material • Palsson, Hubbell, Plonsey and Bronzino, Tissue Engineering • Lanza, Langer and Vacanti, Principles of Tissue Engineering • Prescott, Harley, and Klein’s Microbiology micr221/229 and chee229 text (chapter on Industrial Microbiology)

  9. Search for Stem Cells on: • http://www.eurekalert.org/EurekAlert is run by the American Association for the Advancement of Sciences. • http://scitechdaily.com/Range of news articles, features, and commentaries about science and technology • http://www.sciam.com/index.cfmScientific American website • http://www.reuters.com/news/science?type=scienceNews Reuters news site for stories about science. Search, then select "News and Pictures."

  10. Course evaluation • mid-term “surprise” tests: 20% • product based project: 20% • design based project/report: 20% • final exam: 40% • contributions of cookies and muffins to class: according to level of class participation... bonus marks

  11. History and overview of the products of Biochemical Engineering • Citric acid • Antibiotics • Vaccines • Brewing/Bioethanol • Amino acids • Monoclonal antibodies • Recombinant therapeutic proteins • Farmaceuticals

  12. Principles of Cell Culture Properties and structure of the cell Nomenclature Bacteriophage Growth behavior Determining cell mass Chemical composition of cells

  13. Tissue engineering Tissue culture with mammalian and plant cells Products and medical applications Large-scale plant/mammalian cell culture systems

  14. Metabolism and product formation Metabolic pathways – catabolic/anabolic Biosynthesis Stoichiometry and energetics Control and regulation Industrial strain improvement Screening for new metabolites Molecular genetics and control

  15. Enzymes and enzyme kinetics (versus Monod growth kinetics) Naming and classification Applications – purification of racemic mixtures of amino acids Reaction kinetics (Michaelis-Menten) Inhibition Batch and continuous reactor kinetics

  16. Immobilized biocatalysts Immobilization methods Immobilized enzyme/cell kinetics Mass transfer resistance, effectiveness factors

  17. Product separation and purification Downstream process scheme in protein purification

  18. Design project: A downstream separation train will be examined in detail and each of you assigned one particular unit operation within the purification protocol for a detailed design. The design will be presented in class, followed by a written report.

  19. Product based project Assigned Jan. 11, 2010 To be presented to class at scheduled time as poster presentation Goal is to be familiar in depth with several processes and products involving biologically based processes
