SBI4U Application Project – Unit 1
Enzyme Applications in Industry
In this activity, you will use your knowledge of cell processes and research to understand the
applications of enzyme function to the food, medical, and pharmaceutical industries.
Overall Expectations:
SIV.01 demonstrate scientific investigation skills (related to both inquiry and research) in the four areas
of skills (initiating and planning, performing and recording, analysing and interpreting, and
communicating);
BCV.01 analyse technological applications of enzymes in some industrial processes, and evaluate
technological advances in the field of cellular biology.
Specific Expectations:
SI1.11 communicate ideas, plans, procedures, results, and conclusions orally, in writing, and/or in
electronic presentations, using appropriate language and a variety of formats (e.g., data tables,
laboratory reports, presentations, debates, simulations, models);
BC1.01 analyse technological applications related to enzyme activity in the food and pharmaceutical
industries (e.g., the production of dairy products; breadmaking; the use of enzymes to control reaction
rates in pharmaceuticals) [AI, C];
Enzyme Applications in Industry
In this assignment you will research the application of enzymes in industry. Choose from one of the
topics below and write an approximately 750 word report paper on the use of the enzyme to enhance
the industry. Upload your report to www.turnitin.com when finished.

Explain in detail the enzymes involved, the reactions catalyzed, and the improvement in
the end product.

Discuss why they are being used – more efficient, higher yields, less waste?

What was used before enzymes, if anything?

Discuss the risks, especially to living systems and to the environment.

Discuss the impact of the process on society.

The end of your paper should include your opinion or concerns on this bio-application.

Provide proper in-text citations (using the Harvard method) and an APA list of sources.
Topics
1. Enzymes have been used in the dairy industry for years, in particular for the process of making
cheese through milk coagulation.
2. A large industrial user of enzymes is the starch processing industry. Enzymes are used to convert
starches into glucose syrups. These syrups are used as sweeteners in foods and candy.
3. The dairy industry uses enzymes to breakdown lactose in milk, especially for those who suffer
from lactose intolerance.
4. Lipases are also used in making cheese.
5. Enzymes are now used in the cleaning industry to remove stains. Their action allows clothes with
tough stains to be cleaned at lower temperatures.
6. Enzymes have been used in the leather industry for years to soften hides and clean them.
7. The pulp and paper industry uses enzymes to enhance bleaching and “de-ink” pulp.
8. The textile industry uses enzymes in stone washing and the softening of cotton.
9. Enzymes are used to convert starch into sugar so yeast cells can product ethanol.
10. Enzymes are used as meat tenderizers.
11. Enzymes are now used to make drugs and control reaction rates in pharmaceutical reactions.
12. Enzymes are used as pharmaceutical supplements to treat digestive system disorders such as
celiac disease and lactose intolerance.
13. Enzymes as food supplements to promote health.
