Question	Answer
Biotechnology	use of living things or their components (cells and enzymes) to manufacture useful products, or to carry out useful reactions.
Organisms used in Biotechnology	micro-organisms, plants or animals
Bioprocessing	production of substances using fermentation techniques
Bioprocessing	enzyme controlled reactions to produce a product
use of micro-organisms, such as yeast and bacteria in bioprocessing	produce foodstuffs such as cheeses, yoghurts, breads, beers and wines
More recent uses of bioprocessing	produce antibiotics, drugs, vaccines, methane gas, food colourings and flavours, vitamins, amino acids, sugar sytrups, enzymes and perfumes.
Prevent wasteful use of bioprocessing	enzymes are often immobilised or fixed
Production Method in Biotechnology	micro-organisms are placed in a container along with a suitable substrate on which they can react
Bioreactor	The vessel in which the biological reactions take place
Reasons why contents of the bioreactor are mixed	contents of the bioreactor are mixed
use of a foam breaker	reduce the foam produced during mixing
Getting Oxygen into the Bioreactor	Air is pumped into the vessel
Device used to produce air bubbles when air is passing into the bioreactor	Sparger
quality and yield of the product depends on ..	bioreactors, elimination of micro-organisms, correct rate of mixing, pH and Temperature
Micro-organisms used in biotechnology	Bacteria Fungi
Organism used to produce antibiotics	Bacteria, Fungi, Yeast
