Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Pseudomonas
Concept:

Microbial bioremediation of environmental pollutants.

Solution:

Species of Pseudomonas (such as Pseudomonas putida, the 'superbug') carry plasmid genes encoding catabolic pathways that break down complex petroleum hydrocarbons into harmless metabolites.

Why other options are incorrect:

  • Rhizobium: Symbiotic nitrogen-fixing bacteria residing in root nodules of leguminous plants.


  • Nitrosomonas: Nitrifying soil bacteria that oxidize ammonia into nitrite ions.


  • Streptomyces: Filamentous soil bacteria cultivated primarily for commercial antibiotic production.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
