Bacteria replicate by binary fission, a process by which one bacterium splits into two. Therefore, bacteria increase their numbers by geometric progression whereby their population doubles every generation time. Generation time is the time it takes for a population of bacteria to double in number.
20 minutesWhen food sits out in a temperature range called the danger zone, which is from 40–140°F (4–60°C), bacteria on it can double within 20 minutes.
Given the ideal conditions, bacteria will double in number every: 1 - 2 seconds. 10 - 20 seconds.
