MIRCROBIOLOGY AND BIOTECHNOLOGY
- Mircobiology- The Study of Living things.
- Micro-Organisms( also called Microbes) are too small to be seen by the
naked eye and are found in huge numbers almost everywhere.
- They are present in the Air, Water
and Soil, on our skin and inside
plants, animals and humans.
- There are three types of Micro-organisms.
- Viruses
- Bacteria
- Fungi
- Viruses
- Viruses are the
smallest
micro-organisms
- Viruses cannot reproduce themselves(
they use our cells to multiply, they need
a host)
- All Viruses are said to be
parasites(I.E. They live on or in
another living thing)
- Viruses cause disease to plants,
humans and other animals.
- Virus Diseases
- Measles
- Mumps
- Chicken Pox
- Pollo
- Common Cold
- Flu(Influenza)
- Cold Sores
- AIDs(Caused by HIV)
- Very few chemicals or medicines can kill viruses, for example,
Antibiotics prevent bacterial infections but have no effect on
viruses as viruses are parasites and use other cells to multiply.
- Our bodies fight off most virus
infections when our White blood cells
produce chemicals called Antibodies.
- Bacteria
- Bacteria are larger than viruses
- They don't have
a proper
Nulceus
- In order to grow they require
- Food
- Water
- Suitable pH
- Suitable Tempreture
- Bacteria reproduce asexually
- In asexual reproduction the offsprings are to the
parent as they only came from one parent.
- There are no sex cells (Gametes) involved.
- Useful
- Cause dead plant and animals to decay. This
helps return minerals(nutrients to the soil for
new growth.
- Make food EG-Cheese Burger
- Used in Biotechnology
- Harmful
- Causes Diseases
- TB(Tuberculousis)
- Sore Throat
- Tooth and Gum decay
- Food Posining
- Pneumonia
- Destroys Food EG-Turns milk sour
- Destroys crops in feilds
- Fungi
- These are simple plants that do not contain Chlorophyll.
- Useful
- Cause dead plants and animals to decay
- Some can be eaten EG-Mushrooms
- Used to make alcohol EG-Yeast
- Harmful
- Cause human diseases EG-Athletes foot
- Some are Poisonous
- Causes foods to rot EG-Mold
- Biotechnology-The use
of living things, or parts
of living things, to
produce products of
human value.
- Bacteria and Fungi are used to produce foods, drugs and alcohol.
- Industrial uses
- Yeast is used to produce alcohol in breweries
- Bacteria contains special enzymes that contain a
special characteristic that gets rid of stains such as
fat, ink and blood, this is why it is used in Washing
Ditergents
- Medical uses
- Fungi and Bacteria can be used to make Antibiotics that kill amd prevent diseases.
- Antibiotics
- Hormones-Insulin used to treat diabetes
- Antibiotics- Treat infections
- Chemicals need to clot blood-Used by Haemophiliacs
who cant clot their blood naturally
- Mandatory Experiment
- To investigate the presence of micro-organisms in air and soil
