Biological dinitrogen (N2) fixation is a natural process of significant importance in world agriculture. The demand for accurate… Expand This study examines the potential, magnitude, and causes of enhanced biological N2 fixation (BNF) by common beans (Phaseolus… Expand Biological nitrogen fixation is mediated by the nitrogenase enzyme system that catalyses the ATP dependent reduction of… Expand Some bacteria have the remarkable capacity to fix atmospheric nitrogen to ammonia under ambient conditions, a reaction only… Expand The role of iron in enhancing phytoplankton productivity in high nutrient, low chlorophyll oceanic regions was demonstrated first… Expand N limitation to primary production and other ecosystem processes is widespread. To understand the causes and distribution of N… Expand SUMMARY Biological N2 fixation represents the major source of N input in agricultural soils including those in arid regions. The… Expand Denitrification is a distinct means of energy conservation, making use of N oxides as terminal electron acceptors for cellular… Expand Highlights in biological nitrogen fixation during the last fifty years-- Harold Evans and Robert Burris Phylogenetic… Expand A molecular‐kinetic theory, which explains the temperature dependence of relaxation behavior in glass‐forming liquids in terms of… Expand
