Professor PC Thomas Classes · Answer

(d) : Aspergillus niger and Trichoderma polysporum are used to produce citric acid and cyclospoprin-A respectively. These two are industrial products synthesised with the help of microbes. Citric acid is produced through the fermentation carried out by Aspergillus niger on many carbohydrates (such as cane and beet molasses, etc.). Cyclosporin-A is an important bioactive chemical produced by the fungus Trichoderma polysporum. It is an 11 -membered cyclic oligopeptide. This chemical is used as an immunosuppressive agent in organ transplantation.
