Cell density is controlled by increasing or decreasing flow of culture

1.	Cell density is controlled by increasing or decreasing flow of culture medium in which state?(a) Turbidostat(b) Chemostat(c) Continuous culture(d) Synchronus cultureThis question was posed to me by my college professor while I was bunking the class.The doubt is from Oxygen Uptake in Cell Cultures topic in section Mass Transfer of Bioprocess Engineering
Answer» The correct choice is (b) Chemostat To elaborate: A chemostat (from chemical environment is static) is a bioreactor to which fresh medium is continuously added, while culture liquid containing left over nutrients, METABOLIC END PRODUCTS and microorganisms are continuously removed at the same rate to keep the culture volume CONSTANT.
