Summary Introduction
To sketch: The graphs representing the long-term growth of two populations of bacteria cultured in test tubes, one in which the nutrient medium is replenished and the other in which it is not replenished.
Introduction: Bacterial growth very much depends on the availability of nutrients in the growth media. The concentrations that are higher or lower than the optimum levels can affect the growth of the bacteria in the media. It is very important to replenish the nutrient media timely to ensure continuous and healthy bacterial growth in the media.
