A. Aspergillus niger is a fungus used in the production of citric acid, which is widely used in the food and beverage industry.

B. Microbes especially yeasts have been used from time immemorial for the production of beverages like wine, beer, whisky, brandy or rum. For this purpose the same yeast Saccharomyces cerevisiae used for bread-making and commonly called brewer’s yeast, is used for fermenting malted cereals and fruit juices, to produce ethanol.

C. 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.

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.
