The Thermochemistry of Biological Nitrogen Fixation
نویسنده
چکیده
Using standard thermodynamic data it is shown that the oxidation of glucose by nitrogen to give carbon dioxide and ammonia is an overall reaction that involves a substantial evolution of heat and decrease in free energy. This is not in accordance with literature statements that biological nitrogen fixation is endothermic. In the concluding section a Frost diagram is used to survey the thermodynamic data of oxidation reactions related to nitrogen fixation.

In order to study the effects of biofertilizers on yield quantity and quality of Capsicum annuum L., an experiment was conducted in completely randomized block design with three replications in 2011. All plants were treated before transplanting in pots in greenhouse condition by biological fertilizers including nitroxin and biophosphates. Treatments included 3 concentrations of nitroxin (1:3, 1...
متن کامل“Biological Nitrogen Fixation” Book Summary
Biological nitrogen fixation is a very valuable alternative to nitrogen fertilizer. This process will be discussed in the “Biological Nitrogen Fixation” book. A wide array of free-living and associative nitrogen fixing organisms (diazotrophs) will be covered. The most extensively studied and applied example of biological nitrogen fixation is the symbiotic interaction between nitrogen fixing “rh...

In the present research the growth and metabolism of cyanobacterium Fischerella sp. FS18, isolated from rice fields of Gillan Province (Iran), were evaluated in different nitrogen sources. This strain is a good candidate as biological fertilizer due to high efficiency to N2 fixation. In this way, cells in logarithmic phase of stock were treated with different nitrogen sources (N-free, 1 & 2 mM ...

Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...
