List - II

 (A) Cyclosporin A

 (III) Immunosuppressant

 (B) Streptokinase

 (C) Aspergillus niger

A. Cyclosporin A is a bioactive molecule that is widely used as an immunosuppressive agent in organ transplant patients. It plays a crucial role in preventing organ rejection by suppressing the immune system's response to the transplanted organ. This important medication is derived from the fungus Trichoderma polysporum.

B. Streptokinase, produced by the bacterium Streptococcus and genetically modified, serves as a "clot buster" in the removal of blood clots from the vessels of individuals who have experienced a heart attack.

C. Microbes are also used for commercial and industrial production of certain chemicals like organic acids, alcohols and enzymes. Examples of acid producers are Aspergillus niger (a fungus) of citric acid.

D. Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents. It acts by competitively inhibiting the enzyme responsible for synthesis of cholesterol.
