Microbial Biotechnology – manipulation of microorganisms such as yeast and bacteria
Create better enzymes
More efficient decontamination processes for industrial waste product removal
Used to clone and produce large amounts of important proteins used in human medicine
Aspergillus niger
Saccharomyces cerevisae
Agricultural Biotechnology
Genetically engineered, pest-resistant plants
Foods with higher protein or vitamin content
Drugs developed and grown as plant products
Animal Biotechnology
Animals as a source of medically valuable proteins
Antibodies
Animals as important models in basic research
Gene “knockout” experiments
Design and testing of drugs and genetic therapies
Animal cloning
Source of transplant organs
1. Cloning requires an egg cell, and an adult donor cell. The
(unwanted) chromosomes are removed from the egg cell and discarded. The nucleus, containing the DNA to be cloned, is removed from the donor cell.
2. The donor nucleus is inserted into the empty egg cell, a process called somatic cell nuclear transfer
(SCNT). Afterwards the egg contains a full (adult) set of chromosomes as if it had been fertilised normally.
3. A pulse of electricity, or a chemical 'shock', kick-starts the development process, and the embryo begins to grow.
4. Cell division begins. The subsequent development of the embryo depends upon how successfully the donor nucleus has
're-programmed' the egg.
Forensic Biotechnology
DNA fingerprinting
Inclusion or exclusion of a person from suspicion
Paternity cases
Identification of human remains
Endangered species
Tracking and confirmation of the spread of disease
Bioremediation
The use of biotechnology to process and degrade a variety of natural and manmade substances
Particularly those that contribute to pollution
For example, bacteria that degrade components in crude oil
1989 Exxon Valdez oil spill in Alaska
Aquatic Biotechnology
Aquaculture – raising finfish or shellfish in controlled conditions for use as food sources
30% of all fish consumed by humans worldwide
Genetic engineering
Disease-resistant strains of oysters
Vaccines against viruses that infect salmon and other finfish
Rich and valuable sources of new genes, proteins and metabolic processes with important applications for human benefits
Marine plankton and snails found to be rich sources of antitumor and anticancer molecules
Medical Biotechnology
Involved with the whole spectrum of human medicine
Preventive medicine
Diagnosis of health and illness
Treatment of human diseases

Regulatory Biotechnology
Quality Assurance (QA)
All activities involved in regulating the final quality of a product
Quality Control (QC)
Part of QA process that involves lab testing and monitoring of processes and applications to ensure consistent product standards
How will medical biotechnology change our lives in the years ahead?
Human Genome Project
Research on the function of human genes and controlling factors that regulate genes
Human proteome
