Batch culture in the laboratory

Batch culture is the most general laboratory growth technique in which bacterial growth is studied but it is only one of many. It is ideally spatially temporally and unstructured structured. The bacterial culture is incubated in a closed vessel with a single batch of medium. Some experimental regimes some of the bacterial culture is periodically removed and added to fresh sterile medium. In the great case this leads to the continual renewal of the nutrients.

This is a chemostat also known as continuous culture. It is ideally spatially temporally unstructured and unstructured in a steady state defined through the rates of bacterial growth and nutrient supply. In comparison to batch culture bacteria are maintained in exponential growth phase and the growth rate of the bacteria is known. The Related devices include auxostats and turbidostats.
