Biotechnology: Industry expectations andTechnological EvolutionImplications for the well-educated student.
Part 1: Industry context in Australia and industry requirements • Part 2: An evolutionary/generational definition of biotechnology that captures technological change
Australia: Industry context 2001 • 190 core biotech companies • 460 non-core/support companies • 5,700 employees • +46% fulltime equiv. employees 1999 to 2001 Source: E &Y, 2001
Australia: Industry context 2006 • 427 core biotech companies • 625 medical device companies • Biotech employment doubled 2005 to 2006 • Now > 12,100 people • Operating in diverse fields • Therapeutics, bioprospecting, livestock genetics, molecular biology, biosensors, diagnostics, plant biotechnology, process technology, vaccines Source:Hopper & Thorburn Innovation Dynamics, 2007
Key features of biotechnology • Trans-disciplinary • Rapidly evolving and emerging fields • Nanotech, proteomics, genomics, bioinformatics, PTGS • A very diverse industry • A large number of small companies
Implications for teaching • How should we deliver our teaching, for what seems to be a moving target? • Content? • Teaching methods?
Are we delivering what industry needs? • Core content knowledge • Generic skills

Recommendations • Do not dilute the chemistry
Recommendations • Strong industry demand for certain ‘generic attributes’: • Problem solving • Teamwork • Communication • Creativity • Enthusiasm
Recommendations • Implications for pedagogy • More problem based learning ?? • Core knowledge? • More team based activities ? • More hands-on, task based application of core knowledge?
The future • Students paying more • Changing student expectations (customers) • Changing course preferences • Will there be sufficient numbers of science grads to fuel the new economy? • 23% decline in science enrolments 1989-2002 • Will there be sufficient investment to sustain innovation in Australia? • Will there be investment in core training in fundamentals like chemistry?
Part 2 Evolutionary/generational definition of biotechnology.
Part 2 • A static definition: • Application of biological knowledge for generation of products that are or will be valued by society • Value is contestable and changes over time
Part 2 • Value is contestable and changes over time • Stage of development of the society • Risks to which it is exposed • people give you different definitions
Part 2 • Don’t know what biotechnology is. • Narrow definition • They take a lot for granted. • health/longevity • They don’t know he details of how their food is produced • Supermarket mentality/urbanisation
A Question • What was average life expectancy at birth in Western Europe in 1750?
Answer • 33 years
Why? • No vaccines • No antisepsis • No antibiotics • No analgaesia • No knowledge of germ theory

Definition of biotechnology • An evolutionary/generational definition is best.
First generation • Plant breeding • Collection of herbs for medicine • Animal breeding • Bread making • Wine, beer, sake (Saccaromyces cerevisieae; Actinomyces, Leuconostoc) • Fermented food products • Yoghurt • Cheese • Soy • Chocolate (!)
First generation Bacillus Hanseniaspora Pichia membranifasciens Microorganisms in fermentation and flavour formation of cocoa to make chocolate Saccharomyces cerevisiae
First generation Microorganisms per gram during fermentation of cocoa to make chocolate

Historical facts: • Humans have always guided evolution of crops! • A very small sample of wild plants were chosen and domesticated • More than 10,000 years of genetic selection
Historical facts …..cont • Crops strains and genes have moved around the globe for centuries • All crops we grow today were once wild plants but no crop would survive in the wild anymore (without human support)
They bear little physical resemblance to their wild ancestors Fig.1 Wild varieties of potato from the Americas
Improving on crop plants Development of modern varieties – how was it done? • Hybridization • Disease resistance • Increased yield • Crosses with wild relations • Some do not breed true so it is necessary for farmers to repurchase seeds
The products of these methods have led to crop characteristics (phenotypes) as different as Great Danes and Chihuahuas.

Modern methods of crop improvement: • Are relatively more precise and predictable • Transfer a few genes into crop plants in contrast to random shuffling of older approaches • Can determine exactly where the genes have been inserted (Polymerase chain reaction) • Can measure the effect on all proteins in the plant • Mass spectrometry • HPLC
Benefits • Decreased pesticide usage • Decreased fuel consumption • Decreased crop losses to pests and disease • Papaya anecdote (Hawaii) • Increased nutrient efficiency • nitrogen fixing cereals • Vitamins • Increased crop yields.
GM crops • 220 million acres under GM crops in 2005 • 1/3 in developing countries • In India and Australia , 70% reduction in organochlorine and organophosphorous pesticides
