#Section 5: Bioprocess Engineering and Process Biotechnology
A strain of Azotobacter vinelandii is cultured in a 15-m³ stirred fermenter for alginate production. Under current operating conditions, ka is 0.17 s¹. The solubility of oxygen in the broth is approximately 8 × 10-3 kg m -3.
(a) The specific rate of oxygen uptake is 12.5 mmol g-1h-1. What is the maximum cell concentration supported by oxygen transfer in the fermenter.............in g/l

A strain of Azotobacter vinelandii is cultured in a 15-m³ stirred fermenter for alginate produc- tion. Under current operating conditions, kLa 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
