Bacteria typically reproduce through a process called binary fission, where one cell divides into two. Under favorable conditions, such as optimal temperature, pH, nutrient availability, and oxygen levels, the time taken for this division can be very short, often as little as 20 minutes for some species. This leads to a doubling of the population in each division cycle.

When graphing bacterial growth over time, the number of bacteria increases rapidly after an initial lag phase. This growth pattern forms an exponential curve, indicating that the number of cells doubles at regular intervals. As a result, the growth rate of the bacterial population is not constant but accelerates over time, demonstrating exponential growth. This concept is fundamental in microbiology and crucial for understanding various applications, including wastewater treatment, where bacterial populations play a significant role in breaking down organic matter.
