Match the following product/process to the microorganism involved :
| Product/Process | Microorganism |
|---|---|
| (L) Biopol | (1) Thiobacillus ferroxidans |
| (M) Biopesticide | (2) Pseudomonas putida |
| (N) Bioleaching | (3) Bacillus sphaericus |
| (O) Bioremediation of oil | (4) Alcaligenes eutrophus |
Answer: D
The correct code is (L)-(4), (M)-(3), (N)-(1), (O)-(2).
- Biopol, a polyhydroxybutyrate bioplastic, is made by Alcaligenes eutrophus (now Cupriavidus necator) (4).
- Biopesticide: Bacillus sphaericus produces toxins against mosquito larvae (3).
- Bioleaching of copper and other metals uses Thiobacillus ferrooxidans (1).
- Bioremediation of oil: Pseudomonas putida, including Chakrabarty's engineered 'superbug', degrades hydrocarbons (2).
The other codes misplace at least two organisms, for example giving bioleaching to Pseudomonas.
