Solution Summary
The significance of using a chemostat system is that it is a, "Continuous culture system that allow microbes to grow during exponential phase and maintain its exponential growth and constant biomass for an extened periods of time" (1). Unlike a traditional closed system such as a batch cultures where exponential growth last for only a few generations, the continuous culture systems allow one to study microbial growth at very low nutrient levels and at concentrations close to the natural environments (1). A chemostat system is such a open system where the rate at which sterile medium is fed onto the culture vessel is the same as the rate at which media is removed (1). The chemostat system contains culture medium containing a limited amount of essential nutrient (1). Growth rate is, "Determined by the rate at which new medium is fed into the growth chamber so the final cell density depends on the concentration of the limited nutrient" (1).
