Question

Give scientific reasons.

Microbial enzymes are used instead of chemical catalysts in chemical industry.

Answer 1

Microbial catalysts are also known as biocatalysts. Microbial catalysts are preferred over chemical catalysts for various reasons like: 

• Lesser byproducts are formed in case of microbial enzymes which means the cost of purification is minimised.
• Microbial enzymes can function at low temperatures, pH and pressure, thus saving the energy.
• Enzymes which are used in these processes can be reused as they do not decompose during these processes.
• Use of enzymes also reduces the amount of environmental pollution.

Answer 2

1. These enzymes are active at low temperature, pH and pressure; due to which energy is saved and erosion-proof instruments are also not necessary.
2. Enzymes carry out specific processes; hence unnecessary byproducts are not formed due to which expenses on purification are minimized.
3. In the case of microbial enzymatic reactions, elimination and decomposition of waste material are avoided and enzymes can be reused. Hence, such enzymes are eco-friendly.
