A strain of Azotobacter vinelandii is cultured in a 15-m³ stirred fermenter for alginate produc- tion. Under current operating conditions, k_La is 0.17 s^-1. The solubility of oxygen in the broth is approximately 8 × 10^-3 kg m^-3.

(b) The bacteria suffer growth inhibition after copper sulphate is accidentally added to the fermentation broth just after the start of the culture. This causes a reduction in the oxygen uptake rate to 3 mmol g^-1 h^-1. What maximum cell concentration can now be supported by oxygen transfer in the fermenter?.....g/l
