Bacterial Growth and Mass Increase Calculation in a Patient

Explore the exponential growth of bacteria in a patient infected with E. coli, calculating the final count and increased mass after 24 hours. Learn why the patient does not actually reach the theoretical mass due to cellular processes.

Presentation Transcript

1. Topic Bacterial growth Level GCSE (or any other course for students aged 14-16) Ouctomes 1. To calculate how many bacteria are present after 24h 2. To appreciate why bacterial infections are potentially so dangerous www.thescienceteacher.co.uk | resources for science teachers who like to think

2. E. coli divides about once every 20 minutes. If a patient was infected with one bacterium, how many bacteria would there be after 24 hours?

3. 4722366500000000000000

4. Assume the patient had a mass of 72 kg before infection and each bacterium has a mass of 9.5 x 10-13 g. What would be the new mass of the patient? Why in reality does the patient not reach this mass?

5. Working out 24 hours = 1440 minutes 1440/20 = 72 divisions Each division doubles the number 272 = 4722366500000000000000 bacteria
