Question

Modern detergents contain enzyme preparations of

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

Answer 1

The correct option is C

Acidophiles

The correct option is C:

Explanation of the correct option:

1. Enzymes containing hydrolases, proteases, and cellulases (25-30%) are used to make contemporary detergents.
2. Non-ionic detergents and soaps that work in the pH range of 8 to 10 are available.
3. They operate in a pH range that is higher and more alkaline.

Explanation of the incorrect options:

Option A:

Thermoacidophiles are microorganisms that have evolved ways to survive in abnormally hot, acidic environments, with pH 4 and a temperature of 55°C ideal.

Option B:

1. Microorganisms that develop ideally or excessively well at pH values above 9 are referred to as "alkaliphiles."
2. In contrast, those that grow slowly or not at all at the near-neutral pH value of 6.5 are referred to as “acidophiles.
3. Prokaryotes, eukaryotes, and archaea are all alkaliphiles.

Option D:

1. A thermophile is an extremophile that survives at temperatures ranging from 41 to 122 degrees Celsius (106 to 252 degrees Fahrenheit).
2. Thermophiles are mostly archaea, but they can also be bacteria or fungi.
3. Thermophilic eubacteria are thought to be among the first bacteria to evolve.

Final Answer: - Modern detergents contain enzyme preparations of Acidophiles.
