Detailed explanation-1: -Preventing Food Poisoning From Bacteria Pathogens multiply at a rapid rate. In fact, the Academy of Nutrition and Dietetics reports that a single microorganism can multiply to trillions (yes, trillions!) in just 24 hours when left too long in the “danger zone” between 40 F and 140 F.

Detailed explanation-2: -Incubation can be done at optimal temperatures because different bacteria grow at different temperatures. Nutrients and proper temperature will help them to achieve the lag phase. Hence to observe bacterial growth with an unaided eye, one should keep bacterial cultures for at least 24 hours in the incubator.

Detailed explanation-3: -The incubation period is the time it takes for an infection to develop after a person has been exposed to a disease-causing organism (such as bacteria, viruses, or fungi).

Detailed explanation-4: -Bacteria are able to reproduce at impressive rates: E. coli can double its population every 20 minutes, under optimal conditions. This means that very large population sizes can be achieved within a few hours in the lab; population densities of   109 cells per ml of culture medium are usual in lab experiments.
