A continuously operated 1000 liter CSTR is used for production of biomass from glucose provided by
the feed (feed rate of 100l/h and glucose concentration of 10 g/l). The bacteria show Monod type
growth with a maximal specific growth rate of 0.4/h and an affinity towards glucose of 1.5 g/l. The
biomass yield per substrate consumed is 0.5.
a) What is the specific and absolute production rate of biomass at steadystate condition?
b) At which critical dilution rate is wash out expected?
c) Now a biomass recycling system is included into the setup producing a five times higher cell
concentration than at the reactor outlet. Whatâ€™s the impact on the specific biomass
production rate?
