You get your chemostat stabilized, but after the first few days, you decide that you need a higher cell density (5x10 8 cells/ml) for your experiments to succeed. what parameter would you change to increase the cell density in your culture vessel,

A chemostat refers to the bioreactor to which fresh medium is spontaneously incorporated, while the culture liquid comprising the leftover nutrients, microorganisms, and metabolic end products are removed time to time at the similar rate to maintain the culture volume constant.  

In the given case, in order to increase the density of cell in the culture vessel, there is a need to enhance the concentration of nutrient in the medium being supplied.  

the answer to your question is sperm
