What is Biotechnology? Definition – Process of using living organisms and their parts as tools. Can be summarized through 5 F’s
FOOD Majority of food you eat is genetically modified - what types? - how? - why?
Example #1 - Cheese Enzyme from the lining of calves’ stomachs is used to curdle milk protein
Example #2 –Beer, Wine, Bread Yeast produce ethanol and CO2
Example #3 – Yogurt Bacteria produce lactic acid
FIBER Using bacteria (not chemicals) to convert woodchips to paper pulp Bioremediation – using plants to remove toxins from the ground
FUEL Using crops or manure as a source of renewable energy
FEEDSTOCKS Using starch instead of petroleum to create biodegradable plastics
PHARMACEUTICALS
OLD BIOTECHNOLOGY Genetics changed by selective breeding
OLD BIOTECHNOLOGY + NOT POSSIBLE!!!!!!!!!!
NEW BIOTECHNOLOGY Organisms’ traits can be modified through genetic engineering. + =
NEW BIOTECHNOLOGY Glowing Mouse Video
NEW BIOTECHNOLOGY Genetic engineering – mixing DNA from different species How is cheese production an example of old and new biotech? Got Silk? Video No Mow Grass Video Good Tobacco Video
