Nitrogen fixation was measured in the water column of Lake Mize, Florida, a highly colored, small, deep lake, and in a variety of lacustrine sediments, by the acetylene reduction technique. A consistent seasonal and vertical pattern of fixation occurs in Lake Mize with positive rates noted only...
Anaerobically grown bacteria isolated from the hindgut contents of the termites Coptotermes lacteus (Froggatt), Mastotermes darwiniensis Froggatt and Nasutitermes exitiosus (Hill) were nitrogenase-positive as assayed by acetylene reduction. Nitrogen fixation, confirmed with 15N2, was highest in the is...
Here we report diazotrophy by an archaebacterium, the methanogen Methanosarcina barkeri strain 227. Because it has been proposed that the archaebacteria, eubacteria and eukaryotes diverged at an early stage in evolution 2,3 , the discovery of diazotrophy (N 2 fixation) in a member of the ...
Like Rhizobium, Frankia fixes atmospheric N by root nodulation. Its certain strains can live freely as well. The two N fixation bacteria species differ by hosts. Frankia colonizes actinorhizal plants like alder, bayberry, sweetfern, Avens, etc., enabling them to survive even in infertile soils...
Nitrogen is generally considered one of the major limiting nutrients in plant growth. The biological process responsible for reduction of molecular nitrogen into ammonia is referred to as nitrogen fixation. A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of theBacteriadomain...
Nitrogen fixation by photosynthetic bacteria 来自 Semantic Scholar 喜欢 0 阅读量: 27 作者:ES Lindstrom,RH Burris,PW Wilson 摘要: In 1949, Howard Gest and Martin Kamen published two brief papers in Science that changed our perceptions about the metabolic capabilities of photosynthetic bacteria. Their...
W. B. Bottomley a few questions with regard to his paper on ``Some Effects of Nitrogen-fixing Bacteria on the Growth of Non-leguminous Plants'' (Proc. Roy. Soc., B, lxxxi., 1909, 287), abstracted in NATURE of May 13 (vol. lxxx., p. 327), as I had not the opportunity of ...
nitrogen fixation n 1.(Biology) the conversion of atmospheric nitrogen into nitrogen compounds by certain bacteria, such asRhizobiumin the root nodules of legumes 2.(Chemistry) a process, such as the Haber process, in which atmospheric nitrogen is converted into a nitrogen compound, used esp for...
The biological process responsible for reduction of molecular nitrogen into ammonia is referred to as nitrogen fixation. A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of the Bacteria domain have the capacity to colonize the rhizosphere and to interact with plants. Leg...
