Question

Identify the microorganism which is responsible for the production of an immunosuppressive molecule cyclosporin A :
(1) Streptococcus cerevisiae (2) Trichoderma polysporum
(3) Clostridium butylicum (4) Aspergillus niger

Accepted Answer

Correct Answer: B - Trichoderma polysporumExplanation: Cyclosporin A is a cyclic peptide immunosuppressant produced by the fungus Trichoderma polysporum. It suppresses the immune response by inhibiting T-lymphocyte activation and is widely used to prevent organ rejection after transplantation.Why other options are wrong:- Streptococcus cerevisiae: not a valid organism (Saccharomyces cerevisiae is yeast used in fermentation; Streptococcus are bacteria causing infections)- Clostridium butylicum: produces butyric acid and acetone-butanol through fermentation- Aspergillus niger: produces citric acid and certain industrial enzymesKey Concept: Important bioactive molecules from microbes - Cyclosporin A (Trichoderma polysporum): immunosuppressant; Statin (Monascus purpureus): blood cholesterol lowering; Streptokinase (Streptococcus): clot buster.
