Suppose that 100 L/min are drawn from a fermentation tank and passed through anextraction tank in which the fermentation product (in the aqueous phase) is mixedwith an organic solvent, and then the aqueous phase is separated from the organic phase. The concentration of the desired enzyme ( 3-hydroxybutyrate dehydrogenase )in the aqueous feed to the extraction tank is 10.2 g/L. The pure organic extraction solvent runs into the extraction tank at the rate of 9.5 L/min. If the ratio of the enzyme in the exit product stream (the organic phase) from the extraction tank to the concentration of the enzyme in the exit waste stream ( the aqueous phase )from the tank is D= 18.5( g/L organic)/(g/L aqueous), what is the fraction recovery of the enzyme and the amount recovered per min? Assume negligible miscibility between the aqueous and organic liquids in each other, and ignore any change in density on removal or addition of the enzyme to either stream.
