Bacterial growth is the asexual reproduction, or cell division it is ideally spatially unstructured and temporally unstructured, in a steady state defined by the rates of nutrient supply and bacterial growth in comparison to batch culture. How to measure bacterial growth there are many ways to measure bacteria growth, and some are more complex than others though you sacrifice some consistency in your measurements, the simplest methods are accurate enough and used commonly.
