Determination of Cell Concentration in Bioreactors

Question Consider the growth of enterobacter aerogenes in each of two independent chemostat operations, each of volume 500 L, each operating at steady state. Cell maintenance effects in each bioreactor are negligible, and product formation in each bioreactor is negligible. Growth of E,  aeroge ... Read More

Estimation of Ks and max Values

Question Assuming maintenance is achieved entirely by endogenous metabolism, analysis of the given data showed that max = 0.95 h-1 and Ks = 0.141 mg/mL. On the other hand, assuming maintenance is achieved entirely by substrate consumption, analysis of the given data showed that  max = 2.3 h-1 ... Read More
