  2. Microbiology OB65 investigate the presence of micro-organisms in air and soil OB67 list three common illnesses caused by viruses and three caused by bacteria

  3. What is a micro-organism? OB65 investigate the presence of micro-organisms in air and soil • An organism in a single cell… • Examples of micro-organisms: • Bacteria – e.g. E.coli, Samonella • Virus - e.g. flu virus, HIV

  4. How “micro” is a micro-organism? click on the image to find out… OB65 investigate the presence of micro-organisms in air and soil

  5. How do micro-organisms grow? click on the image to see… OB65 investigate the presence of micro-organisms in air and soil Each cell divides to give two/four/eight…..

  6. OB65 investigate the presence of micro-organisms in air and soil How can I see micro-organisms? If micro-organisms are given the right conditions, they will grow in numbers large enough to let us see a group of them…

  7. OB65 investigate the presence of micro-organisms in air and soil What conditions do micro-organisms need in order to multiply? • Micro-organisms need: • Food • Correct temperature • Suitable medium on which to grow…

  8. OB65 investigate the presence of micro-organisms in air and soil What food do micro-organisms like? Any source of carbohydrate and protein e.g Bovril, chicken stock, or milk…

  9. OB65 investigate the presence of micro-organisms in air and soil What is a suitable temperature? Bacteria grow quickly between 300C and 400C

Micro-organisms can be easily seen growing in colonies if a clear medium is used e.g. agar jelly gelatin

  11. Colonies of bacteria are seen as ‘blobs’ on the surface of the medium… OB65 investigate the presence of microorganisms in air and soil How do I recognise micro-organisms?
