| Microbe | Product | Application | |
| 1. | Monascus purpureus | Statins | Lowering of blood cholesterol |
| 2. | Streptococcus | Streptokinase | Removal of clot from blood vessel |

Which of the following is put into anaerobic sludge digester for further sewage treatment?
| 1. | Floating debris | 2. | Effluents of primary treatment |
| 3. | Activated sludge | 4. | Primary sludge |
Domestic sewage in large cities:
| 1. | is processed by aerobic and then anaerobic bacteria in the secondary treatment in Sewage Treatment Plant (STPs) |
| 2. | when treated in STPs, does not require the aeration step as the sewage contains adequate oxygen |
| 3. | has very high amounts of suspended solids and dissolved salts |
| 4. | has a high BOD as it contains both aerobic and anaerobic bacteria |
Measuring Biochemical Oxygen Demand (BOD) is a method used for:
| 1. | Estimating the amount of organic matter in sewage water |
| 2. | Working out the efficiency of oil-driven automobile engines |
| 3. | Measuring the activity of Saccharomyces cerevisiae in producing curd on a commercial scale |
| 4. | Working out the efficiency of RBCs about their capacity to carry oxygen |
Which of the following statements about methanogens is not correct?

| 3. | They grow aerobically and breakdown cellulose-rich food. |
| 4. | They produce methane gas. |
