YEAST MANNITOL AGAR W/ CONGO RED

Rhizobium can fix atmospheric nitrogen only in root nodules of legumes and that too when it is in the bacteroid stage of its life cycle. It possesses the entire complement of genes for nitrogen fixation, which are normally latent and become active only under special conditions. Rhizobium makes nitrogen available to the plant and in turn, the bacteria derive nutrients from the tissues of the plants. Yeast Mannitol Agar with Congo Red is used for the cultivation of Rhizobium species and for studying root nodulation.
