Write a short note.
Microbial Enzymes
उत्तर
- The enzymes obtained by microbial processes are active at low temperatures. Hence, the process of dirt/muck removal can occur at low temperatures when enzymes are mixed with detergents and energy can be saved.
- Certain enzymes can act specifically on different types of stains (starch, protein, oils, etc.) and hence enable more effective removal of such stains when mixed with detergents.
- Corrosion is a common problem in chemical industries. Using anticorrosive instruments increases the production cost. However, while using microbial enzymes costly anti-corrosive instruments are not required.
- Microbial enzymes are active at low temperature, pH and pressure. Thus, they save energy.
- Enzymes carry out specific processes due to which unnecessary byproducts are not formed. Thus, expenses on purification are minimized.
- In microbial enzymatic reactions, elimination and decomposition of waste material is avoided and enzymes can be reused. Thus, microbial enzymes are eco-friendly.
