Enzymes obtained by microbial process are mixed with detergents.

Explanation

Enzymes obtained by microbial process are mixed with detergents because:
i. In order to remove dirt/muck, detergents and water with high temperature is required. However, cost of heating wate is high.
ii. The enzymes obtained by microbial processes are active ar low temperatures. Hence, the process of dirt/muck removal can occur at low temperatures when enzymes are mixed with detergents and energy can be saved.
iii. Certain enzymes can act specifically on different types of stains (starch, protein, oils, eta.) and hence enable more effective removal of such stains when mixed with detergents.
