A food processing plant generates a waste stream at 1 m/h. The waste that contains glucose at 5g/L will be used to grow yeast cells for use in another operation in the plant. Using this waste stream as the medium, the yeast cells grow at a maximal specific growth rate of 0.69 h. Its yield coefficient is 0.5 g yeast/g glucose. The doubling time increases to 2h if the glucose concentration is reduced to 0.1 g/L. Using a continuous culture that is operated at a steady state with a dilution rate of 0.62 h, a) calculate the daily output of yeast cells. b) calculate the size of the bioreactor. Question 2 Certain microbial cells with the chemical formula of C4 4H73N0.860 are grown on glucose (CH2O6) and hexadecane using ammonia (NH3). The cells can convert 67% of carbon source to biomass. a) Calculate the stoichiometric coefficients. b) Calculate the biomass yield from substrate and oxygen.
