BATCH CULTURE IN MICROBIOLOGY
When bacteria are grown in the lab then its growth has been determined. In a batch culture which is called as closed system because no food are added and wastes are not removed.
This technique is used to growth microorganisms by providing limited supply of nutrients and when these nutrients are depleted, or wastes are accumulated or some other factor then culture will decline and the products made by organisms are harvested from the culture.
To summarise, batch culture is defined as a closed system which is used in fermentation by providing fixed amount of nutrients and no more addition of nutrients during incubation period.
