#Section 5: Bioprocess Engineering and Process Biotechnology

A bacterial fermentation was carried out in a reactor containing broth with average density 1200 kg/m3 and viscosity 0.02 N.s/m2 . The broth was agitated at 90 rpm and air was introduced through the sparger at a flow rate of 0.4 vvm. The fermenter was equipped with two sets of flat blade turbine impellers and four baffles. The dimensions of vessel, impellers and baffle width were: tank diameter, Dt =4 m; impeller diameter, Di = 2 m; baffle width, Wb = 0.4 m; also, the liquid depth was H = 6.5 m

In a batch production of penicillin, 40 m3 capacity of the plant, sterile air is required to be supplied. The bioreactor requires 1 vvm (volume of air/volume of broth. min). The incoming air contains 3000 cells/m3of air, for 100 hours operation. Calculate the depth of filter if the penetration of bacteria is 1 in 1 million.

#Section 5: Bioprocess Engineering and Process Biotechnology

Microbial cells are separated from a culture broth at a flow rate of 3.35 x10-3m3/5. Assume the cells are spherical with average diameter of 111m. Select a centrifuge that can perform this separation. Given data: pcell =1.1, Pwater,=997 kgm-1 at 25 °C; Pbroth = 3pwater, and the viscosity of water is 0.9 x 10-3 N.s/m2

#Section 5: Bioprocess Engineering and Process Biotechnology

Microbial cell recovery is carried out in a continuous disc-stack centrifuge. The centrifuge is operated at 5000 rpm for separation of baker's yeast. At a feed rate of 60 1/min, 50% of the cells are recovered. At constant speed, solid recovery is inversely proportional to flow rate. What flow rate is required to recover 90% of cells if the centrifuge speed is fixed at 5000 rpm?
