BACTERIAL MATH ACTIVITY
On Thursday night you are up late studying for your microbiology exam the next day (even though you know that cramming the night before is NOT the correct way to study for this class).
Your lab partner stops by and the two of you decide to order a pepperoni pizza. By 1 A.M. you are exhausted. One piece of the pizza is left but you are too tired to wrap it up and put it in the refrigerator, so you leave it in the box on your desk and go to bed. While closing the lid of the box you sneeze and deposit 1000 Staphylococcus aureus cells onto the pizza. At room temperature this organism has a generation time of 30 minutes.
In the morning you wake up, still exhausted, and realize you already late for your 8:30 A.M. class. Too late to get breakfast, you grab the left over pizza and rush to class.
How many Staphylococcus aureus cells are on the piece of pizza you ate in the morning? (5)

Explanation / Answer
As per your paragraph the generation time is 30 minutes. So in one hour 1 bacterium can produce 4 bacteria
Please find the cell number per hour to hour.
2am - 4000
3am - 16000
4am - 64000
5am - 256000
6am - 1024000
7am - 4096000
8am - 16384000
8:30 am - 32768000 cell were present at the time of eat.
