Microbial enzymes.

Explanation

(i) Microbial enzymes have replaced chemical cataysts in chemical industry. These enzymes are active at low temperature, pH and pressurre , due to which energy is saved and erosion - proof instruments are also not necessary.
(ii) Enzymes carry out specific processes, hence unnecessary by - products are not formed due to which expenses on purification are minimised.
(iii) In case of microbial enzymatic reactions, elimination and decomposition of waste material is avoided and enzymes can be reused. Therefore, enzymes are eco - friendly.
(iv) Oxidoreductases, transferases , hydrolases, lyases, isomerases , ligases , etc. are microbial enzymes.
(v) Enzymes are mixed with detergents for removal of dirt at low temperature.
(vi) Glucose and fructose syrup can be obtained from corn flour by action of enzymes obtained from bacilli and Streptomyces.
(vii) Microbial enzymes are used in various industries like cheese, plant extract , textile , leather , paper , etc.
