Interactions between nitrogen fixation and osmoregulation in the methanogenic archaeon methanosarcina barkeri 227
The nitrogenase enzyme complex of Methanosarcina barkeri 227 was found to be more sensitive to NaCl than previously studied molybdenum nitrogenases are, with total inhibition of activity occurring at 190 mM NaCl, compared with >600 mM NaCl for Azotobacter vinelandii and Clostridium pasteurianum nitrogenases. Na+ and K+ had equivalent effects, whereas Mg2+ was more inhibitory than either monoval...
متن کاملMolecular genetics of symbiotic nitrogen fixation.
Although most organisms, including all eucaryotes, cannot assimilate atmospheric dinitrogen (N2), a group of evolutionarily divergent procaryotes are able to reduce N2 directly to ammonia (nitrogen fixation) under a variety of physiological conditions. The molecular genetics of nitrogen fixation has been studied primarily in Klebsiella pneumoniae because of its close taxonomic relation to Esche...
متن کاملNitrogen Fixation
Plant growth is directly dependent upon an adequate supply of fixed nitrogen. Water and fixed nitrogen are the most common limiting factors for plant growth.There is an abundance of nitrogen in the atmosphere, but it is in the form of the relatively inert gas, N2, and this must be converted chemically or biologically into a more active form before plants can utilize it. Chemical fixation most c...

Cyanobacterial Nitrogen Fixation (CYANOFIX)
The European Science Foundation acts as a catalyst for the development of science by bringing together leading scientists and funding agencies to debate, plan and implement pan-European initiatives. This ESF programme builds on the longstanding European research tradition in cyanobacterial nitrogen fixation. It is, however, the first coordinated European interdisciplinary programme in the field...
