Give scientific reasons.

Enzymes obtained by microbial process are mixed with detergents.

Instead of chemical catalysts, nowadays microbial enzymes are used in chemical industry. These enzymes are active at low temperature, pH and pressure due to which energy is saved and erosion-proof instruments are also not necessary. Process of dirt / muck removal occurs at low temperature too due to mixing of enzymes with detergents. Hence the enzymes obtained by microbial process are mixed with detergents.
