- 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.
