Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.
