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. Biofertilisers are organisms that enrich the nutrient quality of the soil. The main sources of biofertilisers are bacteria, fungi and cyanobacteria. The nodules on the roots of leguminous plants formed by the symbiotic association of Rhizobium. These bacteria fix atmospheric nitrogen into organic forms, which is used by the plant as nutrient. Other bacteria can fix atmospheric nitrogen while free-living in the soil (examples Azospirillum and Azotobacter), thus enriching the nitrogen content of the soil.

D. 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.
