Problem 2: Serratia marcescens bacteria are used for the production of threonine. The specific oxygen uptake rate of S. marcescens in batch culture is 6 mmol O2 g1 h 2. It is planned to operate the fermenter to achieve a cell density of 50 g 1-1. At the fermentation temperature and pressure, the solubility of oxygen in the culture liquid is 8 x 10-3 kg m3. The concentration of oxygen in the culture liquid is 3 x 10-4 kg m-3....
