Question

Which of the following enzymes is not used in making detergent?
A. Lipase
B. Cellulase
C. Protease
D. Peptidase

Answer 1

Biological detergent is a powdered detergent that uses enzymes obtained from microorganisms, like bacteria that are prepared to live in hot springs. They contain protein digestive enzymes formed by genetically engineered bacteria. Most of the clothes stains, such as blood and sweat, are proteins.

Complete answer:
Peptidase enzyme helps to break the peptide linkage between the amino acid chains and converts the protein into the amino acid. It is not used for making the biological detergent because it can easily start the reaction with the skin and digest its proteins. Proteolytic enzymes such as peptidase are available in bacteria, archaea, some species of algae, certain viruses, and plants; although they are very common in animals. Microbial lipase is widely broadened in its enzymatic characteristics and substrate specificity, allowing it very desirable for industrial uses. This analysis explains the use of microbial lipases in detergents. Enzymes can lower the environmental burden of detergent products because chemicals used in traditional cleaning agents are reduced; they are biodegradable, less toxic, and therefore do not leave harmful residues. Cellulase, which are enzymes that break cellulose, are secreted by bacteria, fungi, and protozoa. Cellulase-type enzyme facilitates stain reduction, brightens up the color, and softens cotton-containing clothes by effectively scraping cotton cellulose microfibrils from wash-damaged cotton clothes. The issue with Cellulase is to balance the effects of damage to the performance of cotton after frequently repeated washings. However, the cellulose enzyme has attributes that make it feasible to change the structure of cellulose fiber in cotton-based blends. Proteases are by far the most commonly used enzymes in the detergent sector. They remove protein stains like grass, blood, egg, and sweat. These organic stains seem to bind strongly to textile materials. Proteins act as glues, stopping water-borne detergent mechanisms from eliminating any of the other soiling factors, such as pigments and dirt.
So, the correct answer is option (D).

Note: Bio detergents enhance the longevity of the clothes and retain the brightness of the color. Bio detergents are less toxic in nature by substituting enzymes for harmful chemicals. They are exceptional cleaners and removers of stain. Bio detergents are softer than cloth.
