Microbiology and Biotechnology
Microbiology
the study of small living things
micro-organisms are small livign things, too small to be seen
almost everywhere
viruses, fungi and bacteria
Viruses
smallest, cannot reproduced, increase in numbers by invading cells
parasites
HIV / AIDS, Mumps, measles, chicken pox, polio, colds, flu and cold sores
very few medicines kill viruses, body fights off viruses, white blood cells produce antibodies
Bacteriia
very simple, no nucleus, reproduce with food, water, suitable temperature and pH
can produce very rapidly
live on dead material, decomposers, decay vital as returns materials to soil
good and bad
good
cause dead plants and animals to decay
make food cheese, yoghurt, butter
used in biotechnology
bad
cause disease
destroy foods
destroy crops in fields
tetanus,TB, pneumonia, sore throats, tooth / gum disease, food poisoning, cholera, anthrax
antibiotics fight off bacteria and fungi, kill or prevent reproduction, penicillin
fungi
simple plants no chlorophyll, cannot make food, parasites on plants and animals
decomposers, single celled (yeast) many form long threads, underground come up as reproductive structures
good and bad
good
cause dead plants and animals to decay
can be eaten
used to make alcohol
cause disease (athlete's foot)
Cause food to rot
some are poisonous
Biotechnology
use of living things or parts of living things to produce useful products
plants animals and micro-organisms used, enzymes used also
bacteria and fungi such as yeast used to make foods, drugs, alcohols, hormones and enzymes, used to make alcohol and raise dough (yeast)
fungi and bacteria used to make antibiotics, micro-organisms are being altered (adding genes) to allow production of new products
industrial uses of biotechnology
yeast used to make alcohol
bacteria used to make enzymes, added to powders and stain removers, remove difficult stains, fat, blood and ink, biological detergents
