Bioactive molecules from various microorganisms offer significant medical and industrial benefits. For instance, statins derived from Monascus purpureus reduce cholesterol and associated cardiovascular risks. Cyclosporin A, produced by Trichoderma polysporum, acts as an immunosuppressant crucial for organ transplantation. Penicillin, an antibiotic sourced from Penicillium notatum, effectively treats bacterial infections. Citric acid from Aspergillus niger and lactic acid from Lactobacillus are widely used as food preservatives and additives. The bioactive compounds synthesized by these microorganisms underscore their importance across medicine, agriculture, and various industries.
