Bacterial Growth
Bacteria are microscopic single-celled organisms present in a variety of shapes and sizes; cocci, bacilli and spirochetes. They reproduce asexually through binary fission. The time taken by the bacterial population to double itself is known as generation time. It varies among different species such as Clostridium perfringens have a rapid doubling time of 10 minutes, while Mycobacterium tuberculosis, exhibits a slower growth rate, with a doubling time of 12 to 16 hours. Bacterial growth can be influenced by various factors, including nutrient availability, temperature, pH, oxygen level, genetic factors and the presence of inhibitory substances.

Bacterial Growth Curve – Phases, & its Factors
Bacterial Growth curve is a graphical representation of the changes in the number of bacteria in a population over time. The curve is divided into four phases: the lag phase, the exponential (log) phase, the stationary phase, and the death phase. These phases describe the population dynamics of bacteria as they grow in a closed system like a culture medium. In this article, we will learn about the bacterial growth curve, its phases, application, and importance.
