 a) Chalcone synthase catalyzes the conversion of p-Coumaroyl-CoA into Chalcones

 b) Substrate for Chalcone synthase is chalcone

 c) CHS activity increased by environmental factors, such as light, and fungal infection

 d) Chalcone synthase is enzyme in flavonoid biosynthesis catalyzes stepwise condensation into p-Coumaric acid by using Malonyl-CoA molecules

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.

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: p_cell =1.1, P_water,=997 kgm^-1 at 25 °C; P_broth = 3p_water, 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?
