Question

Among the following pairs of microbes, which pair has both the microbes that can be used as biofertilizers?

A

Aspergillus and Rhizopus

B

Rhizobium and Rhizopus

C

Cyanobacteria and Rhizobium

D

Aspergillus and Cyanobacteria

Step-by-Step Solution

According to the text, the main sources of biofertilisers are bacteria, fungi, and cyanobacteria. Specifically, Rhizobium forms symbiotic associations with root nodules of leguminous plants to fix atmospheric nitrogen . Cyanobacteria (like Anabaena, Nostoc) are autotrophic microbes that can fix atmospheric nitrogen and serve as important biofertilisers, especially in paddy fields . In contrast, Aspergillus is noted for producing citric acid and Rhizopus is a bread mould , neither of which are described as biofertilisers in this context.

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Microbes in Human Welfare. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
