Question

How to identify Rhizobium?

Answer 1

Rhizobium:

1. A bacteria called Rhizobium is found in soil and aids in the nitrogen fixation process in leguminous plants.
2. It grows nodules and affixes to the leguminous plant's roots.
3. These nodules capture air nitrogen and transform it into ammonia, which the plant can use to grow and develop.
4. A typical nodulation experiment can be used to distinguish between different Rhizobium species.
5. This requires the development of a host plant that has been injected with the Rhizobium species.
6. They resemble elongated rod-shaped cells with dimensions of 0.5–0.9 m in width and 1.2–3 m in length when viewed under a microscope.
