Solution
| Micro-Organism | Usefulness to Humans | |
| (a) | Nucleopolyhedrovirus |
|
| (b) | Saccharomyces cerevisiae |
|
| (c) | Monascus purpureus | Statins produced by it work as blood cholesterol-lowering agents. |
| (d) | Trichoderma polysporum | It produces cyclosporin A, which works as an immunosuppressant. |
| (e) | Penicillium notatum | It is a source of penicillin, an antibiotic. |
| (f) | Propionibacterium shermanii | It helps in the ripening of Swiss cheese. It is also responsible for the appearance of large holes in the cheese, as it produces high amounts of carbon dioxide. |
