A. Aspergillus niger is a fungus known for its ability to produce citric acid. It is widely used in the food and beverage industry for the production of citric acid, which is commonly used as a flavoring agent and preservative.

B. 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.

C. Ethanol also known as ethyl alcohol, is commonly produced through the process of fermentation. Fermentation involves the conversion of sugars into alcohol and carbon dioxide by the action of microorganisms, typically yeast (Saccharomyces cerevisiae).

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.
