A fermentation broth with an actual DO concentration of 2 ppm has a biomass concentration of 0.2g dry cell per litre of the medium. If the mass transfer coefficient on the liquid phase and the saturation, DO concentration were 0.02/s and 0.32 mmol/l respectively, calculate the specific rate of oxygen consumption by the micro-organism assuming a steady state condition. Also calculate the specific growth rate for an oxygen yield coefficient of 2g dry cell/s of oxygen.
