a) Organic Solvent Fractionation: This technique involves the use of organic solvents to separate enzymes from other components in a mixture based on their solubility. Enzymes can be selectively precipitated out of the solution by adding an organic solvent, allowing for their purification.
b) Salting Out: Salting out is a method used to precipitate proteins, including enzymes, from a solution by adding high concentrations of salts. The salts reduce the solubility of the proteins, causing them to aggregate and precipitate out of the solution, which can then be separated and purified.
c) Ultrafiltration: Ultrafiltration is a membrane-based separation technique that is used to separate enzymes based on their size and molecular weight. The process involves passing a solution through a membrane with specific pore sizes, allowing smaller molecules like enzymes to pass through while larger molecules are retained.
d) Dialysis: Dialysis is a technique used to separate enzymes from other components in a solution based on their size and charge. The process involves placing the solution containing the enzymes in a dialysis bag or tubing with a semi-permeable membrane that allows small molecules like enzymes to pass through while retaining larger molecules. This allows for the purification and concentration of enzymes.

a) Organic Solvent Fractionation:
- Principle: Enzymes are sparingly soluble in organic solvents. By adding increasing amounts of organic solvents, enzymes with varying solubility can be fractionated.
- Application: Purifying enzymes by removing contaminants with different solubility characteristics.
b) Salting Out:
- Principle: Enzymes have varying solubility in solutions with different salt concentrations. Increasing the salt concentration can lead to enzyme precipitation.
- Application: Precipitating and concentrating enzymes from dilute solutions.
c) Ultrafiltration:
- Principle: Enzymes are separated from smaller molecules based on their size using a semipermeable membrane. Enzymes pass through, while contaminants are retained.
- Application: Concentrating, purifying, and removing small contaminants from enzyme solutions.
d) Dialysis:
- Principle: Enzymes are separated from smaller molecules based on their size using a semipermeable membrane. Contaminants pass through the membrane, while enzymes are retained.
- Application: Removing low molecular weight contaminants (e.g., salts, buffers) from enzyme solutions.
