Question

Modern detergents contain enzyme preparations of

• A. Thermoacidophiles
• B. Thermophiles
• C. Alkaliphiles
• D. Acidophiles

Answer 1

The correct option is C Alkaliphiles

Thermoacidophiles :
Thermoacidophiles are bacteria that live in high temperatures and low pH.

Thermophiles :
Thermophilic bacteria have thermostable enzymes. Therefore, they find application in degradation of crude oil at high temperature.

Acidophiles :
Acidophiles are bacteria that live in low pH and are used for bioleaching of metals present in low grade ores.

Alkaliphiles :
Alkaliphiles are bacteria that live in high alkaline conditions. Detergents have a high pH. Therefore, enzymes isolated from these bacteria are used in detergents as they can work best in the alkaline pH.

Final answer :
(D) Alkaliphiles
