Consider the following statements
$I.$ Yeast used in making bread and beverages is a prokaryotic fungus
$II.$ Streptokinase is produced by Streptococcus and modified by genetic engineering is used as a clot buster
$III.$ Lipases are added in detergent for removing only stains from laundry
$IV.$ Pectinases are used in clearing fruit juices
Which of the statement given above are correct?
$I, II, III$ and $IV$
$I, II$ and $III$
$II, III$ and $IV$
$III$ and $IV$
Solution
Yeast used in baking and the alcohol in alcoholic beverages is a type of eukaryotic fungus. Streptokinase is an enzyme obtained from the cultures of some haemolytic bacterium Streptococcus and modified genetically to function as clot busters. Lipases are lipid dissolving enzymes that are obtained from Candida lipolyticaand Geotrichumcandidum. They are added in detergents for removing oily stains from laundry. Pectinases are obtained commercially from Byssochlamys fulva. Along with proteases, they are used in clearing of fruit juices
