Diazotrophic microorganisms
WebDiazotrophic bacteria that form symbioses with legumes are referred to as rhizobia, and their presence in soils is widespread across the planet. Establishing the symbiotic relationship requires the plant root and bacteria to find each other in the soil, involving a molecular dialogue between host plant roots and rhizobia, which, in turn ...

See more Diazotrophs are bacteria and archaea that fix gaseous nitrogen in the atmosphere into a more usable form such as ammonia. A diazotroph is a microorganism that is able to grow without external sources of fixed nitrogen. Examples … See more The word diazotroph is derived from the words diazo ("di" = two + "azo" = nitrogen) meaning "dinitrogen (N2)" and troph meaning "pertaining to food or nourishment", in … See more Under the laboratory conditions, extra nitrogen sources are not needed in free living diazotrophs, and carbon sources (such as sucrose, glucose) and a small amount of inorganic … See more In terms of generating nitrogen available to all organisms, the symbiotic associations greatly exceed the free-living species with the exception of cyanobacteria. Diazotroph plays an important roles in nitrogen cycle of the earth. In the terrestrial ecosystem, … See more Diazotrophs are scattered across Bacteria taxonomic groups (as well as a couple of Archaea). Even within a species that can fix nitrogen there may be strains that do not. Fixation is shut off when other sources of nitrogen are available, and, for many species, … See more Biofertilizer Diazotroph fertilizer is a kind of biofertilizer that can use nitrogen-fixing microorganisms to … See more • Marine Nitrogen Fixation - The Basics (USC Capone Lab) • Azotobacter • Rhizobia See more
