batch culture

batch cul·ture

a technique for large-scale production of microbes or microbial products in which, at a given time, the fermenter is stopped and the culture is worked up.

batch culture

A closed bacterial culture system with specific nutrient, temperature, pressure, aeration and other environmental conditions to optimise growth. Because nutrients are not added, nor waste products removed during incubation, batch cultures can only complete a limited number of life cycles before nutrients are consumed and growth stops.

batch culture

a culture in which a certain volume of MEDIUM is inoculated with CELLS. The cells grow in the medium and are exposed to changing conditions, as nutrients are depleted and waste products accumulate. The system is a closed one, with no additions or removals during the period of incubation.
