Modern detergents contain enzyme preparations of
A)Acidophiles
B)Alkaliphiles
C)Thermoacidophiles
D)Thermophiles
Solution
The laundry enzymes are designed to work in various conditions and target a variety of stains like oil, dirt, and proteins and should be able to work in presence of both ionic and anionic detergents.
Complete answer:
The enzymes used in the detergents aim to catalyze the reactions between stains and water solution thus improving the efficiency in removing stains. The laundry enzymes must be able to work in many ranges of adverse conditions like high and low temperatures, acidic and basic conditions, and high ionic strength. The main enzymes are proteases, cellulose, and alpha-amylase.
Option A: The acidophiles are found in acidic areas and have an application in the biomining process to obtain metals from impure metals and these enzymes are used in food industries therefore this is an incorrect option.
Option B: The modern detergents are prepared by the enzymes (25-30%) containing hydrolases, proteases, and cellulases. There are non-ionic detergents and soaps which can act within the pH of range 8 - 10. They work in the pH range which is higher and alkaline. Thus, the correct answer is option B i.e. Alkaliphiles.
Option C: The Thermoacidophiles are found in the deep-sea vents and are mainly used for bioremediation and bioleaching; this is an incorrect option.
Option D: since the above option is correct therefore is an incorrect option.
Hence, the correct answer is option (B)
Note: Modern detergent contains enzymes preparations of alkaliphiles. Alkaliphiles live in alkaline environments like soda lakes, or alkaline soil. The pH level in alkaline substances is from about 9 to 11 on the pH scale.
