| (P) | Cellulose | 1. | Pseudomonas aeruginosa |
| (Q) | Alginate | 2. | Alcaligenes faecalis |

Select an option to attempt
Correct Answer: Option B
Explanation
Matching polysaccharides to microbial producers: Cellulose — produced by Gluconacetobacter hansenii (= Acetobacter xylinum); also Agrobacterium, Sarcina. Alginate — produced by Pseudomonas aeruginosa (mucoid strains in CF lungs) and Azotobacter vinelandii; also seaweed (brown algae), but microbially: Pseudomonas. Curdlan —-1,3-glucan produced by Alcaligenes faecalis (= Agrobacterium biovar 1 strain). PHB (Polyhydroxybutyrate) — produced by Ralstonia eutropha (now Cupriavidus necator); also Bacillus megaterium. The match P-3 (cellulose-Gluconacetobacter), Q-1 (alginate-Pseudomonas), R-2 (curdlan-Alcaligenes), S-4 (PHB-Ralstonia) — as given in the explanation.
