- 1What is an uncontaminated cult of bacteria?It is a culture that only contains selected bacteria – and so is not contaminated with bacteria from anywhere else.
- 2How can bacteria be grown?Bacteria multiply by simple cell division (binary fission) as often as once every 20
minutes if they have enough nutrients and a suitable temperature.
Bacteria can be grown in a nutrient broth solution or as colonies on an agar gel
plate. - 3Why might uncontaminated clutures be needed?To test the effectiveness of an antibiotic or disinfectant.
The most effective bacteria or disinfectant is the one that kills the most bacteria.
This does not always mean it is the best one to use however as it may be harmful to health or ineffective against other bacteria.
