In legumes and a few other plants, the bacteria live in small growths on the roots called nodules. Within these nodules, nitrogen fixation is done by the bacteria, and the NH3they produce is absorbed by the plant. Nitrogen fixation by legumes isa partnership between a bacterium and a plant....
Biological nitrogen fixation (BNF) is accomplished by a group of microorganisms, known as diazotrophs through the catalytic action of nitrogenase enzyme system. N-fixing microbes exhibit a wide diversity in terms of their habitat. Some are free-living, whereas others form symbiotic associations with ...
Nitrogen fixation, in which nitrogen gas is converted into inorganic nitrogencompounds, is mostly (90 percent) accomplished by certainbacteriaandblue-green algae. A much smaller amount of free nitrogen is fixed by abiotic means (e.g.,lightning,ultraviolet radiation, electrical equipment) and by conv...
The fixation of molecular nitrogen into bioavailable compounds for cellular anabolism is a process restricted to some bacteria. Such bacteria are termed diazotrophs, as they obtain all their nitrogen by fixing molecular nitrogen. During biological nitrogen fixation (BNF) molecular nitrogen is reduced (...

(iv) determining the level of plant nitrogen gained by nitrogen fixation by isotopic, 15N-based methods. The method according to any one of claims 1 to 6, wherein the nitrogen fixing microorganism is a bacterium, preferably of family Rhodocyclaceae. The method to any one of claims 1 to...
Currently, nitrogen injection is mainly accomplished through pre-buried pipe, drag pipe, borehole and intubation pipe [15,16,17,18,19,20,21]. For the pre-buried pipe method, seamless steel pipe is placed along the main gate of the working face first. And then, when the working face adva...
(NH4+) is taken up by plants or converted to nitrite (NO2−) and then nitrate (NO3−) by bacteria. These processes ofbiological uptakeand nitrification releasehydrogen ions, acidifying the soil and downstream aquatic systems. Other processes, such as increasedbiological nitrogen fixationor ...
