WebSynonymously known as non-symbiotic bacteria, free-living nitrogen-fixing bacteria are a particular class of bacteria that are not directly dependent on other living organisms for survival. These are usually well adapted to establish their survival in a highly competitive environment while playing an essential role in nitrogen fixation. WebApr 26, 2010 · In symbiotic nitrogen fixation, the establishment of the bacterium inside the host root and nodule development is a complex process and involves the processes like recognition and infection of the host root, differentiation of the root nodules, proliferation of the bacteria and transformation of the bacteroids in nodules (Schlegel, 1991).
WebJun 1, 1999 · Applying silicon in the form of metasilicic acid (H 4 SiO 3) or silicic acid (H 4 SiO 3) to Bradyrhizobium-infected, hydroponically grown cowpea seedlings resulted in a significant (P [les ]0.05) increase in the number of nodules, nodule dry matter, and nitrogen fixed on a per plant basis.
