| b. Swiss cheese | (ii) Methanobacterium |
| c. Cyclosporin A | (iii) Monascus |
| d. Biogas | (iv) Propionibacterium |
Options:
Answer:
Solution:
The large holes in ‘Swiss cheese’ are due to production of a large amount of CO2by a bacterium namedPropionibacterium sharmanii.
Cyclosporin A, that is used as an immunosuppressive agent in organ-transplant patients, is produced by the fungusTrichoderma polysporum. Statins produced by the yeastMonascus purpureushave been commercialised as blood-cholesterol lowering agents. It acts by competitively inhibiting the enzyme responsible for the synthesis of cholesterol.
Biogas is a mixture of gases (containing predominantly methane) produced by the microbial activity and which may be used as fuel. Certain bacteria, which grow anaerobically on cellulosic material, produce a large amount of methane along with CO2and H2. These bacteria are collectively called methanogens, and one such common bacterium is Methanobacterium. These bacteria are commonly found in the anaerobic sludge during sewage treatment.
