What is Staphylococcus Aureus?
Reproduce through binary fission, a method of asexual reproduction in which one cell divides into equal parts to form two cells.
Average growth rate at optimum is about 42 minutes. If you start with one cell, you'll have approximately 8.6 billion at the end of one day.
Optimum growth temperature is 17 degrees centigrade. (Approx 62.6 degrees Fahrenheit)
Optimal food for growth is chicken broth at 17 degrees centigrade.
