Problem 1: serratia marcescens bacteria are used for the production of threonine. the maximum specific oxygen uptake rate of s. marcescens in batch culture is 4 mmol o2 g-1 h -1 . it is planned to operate the fermenter to achieve a maximum cell density of 50 g l-1 . at the fermentation temperature and pressure, the solubility of oxygen in the culture liquid is 8 × 10-3 kg m-3 . the concentration of oxygen in the culture liquid is 0.5 × 10-3 kg m-3 . at a particular stirrer speed, kla is 0.17 s -1 . under these conditions, will the rate of cell metabolism be limited by mass transfer?
