Mass production of bacteria Is there a way to mass produce a certain species of bacteria? Answers I am looking for should not involve a Petri dish: I am only interested in protocols involving, perhaps, more efficient mediums to grow the bacterium-in-question. Is it done with any yet? In a factory or where etc? How is it done?

The fed batch culture is a means of bacterial production that is used in industrial setups. Nutrients are fed into the chamber with controlled ideal conditions for growth of a particular species of microorganisms.

Upon reaching the desired yield temperatures can be increased (depending on the species of bacteria) to facilitate spore formation for eventual harvesting.
