The following are some of the chemicals and acids produced by useful microbes for various commercial purposes:

• Citric acid is obtained from fungus, Aspergillus niger. Citric acid can be used in manufacturing of drugs, flavouring agents, disinfectants, etc.
• Butyric acid is produced by the bacterium Clostridium butylicum. It can be used in food as flavoring substance as well as in pharmaceuticals.
• Cyclosporin A is produced by Trichoderma polysporum, a fungus. It is a suppressor of the immune system, and used in the case of patients who have undergone organ transplant.
• Statins are produced by yeast Monascus purpureus. It helps in lowering the blood cholesterol levels by inhibiting the enzyme responsible for cholesterol synthesis in the body.
