Non-Symbiotic Nitrogen FixationDiazotrophs Microorganisms which pass independent life and fix atmospheric nitrogen are known as free living diazotrophs. There are two groups of such micro-organisms : bacteria and cyanobacteria (blue-green algae). Based on the mode of nutrition (carbon,...
Nitrogen fixation by free-living organisms is compared with the process of symbiotic nitrogen fixation. Inorganic nitrogen metabolism is discussed with regard to the nitrification and denitrification processes. The various mechanisms of assimilation of inorganic nitrogen by microorganisms are described in ...
Transfer of nitrogen fixation (nif) genes from diazotrophs to amenable heterologous hosts is of increasing interest to genetically engineer nitrogen fixation. However, how the non-diazotrophic host maximizes opportunities to fine-tune the acquired capaci

(<10,000 yrs). Similarly, previous studies in this region also suggest that free-living and symbiotic N-fixation are unlikely to provide additional sources of inorganic N that we did not measure72. While historic rates of N deposition are inaccessible at the scale of individual focal trees ...
