WebNational Center for Biotechnology Information WebMay 19, 2016 · Symbiotic nitrogen fixation has often been thought of as an oxygen paradox (Appleby 1984). The components necessary to enzymatically reduce nitrogen to ammonia are oxygen labile, yet the organisms are generally obligate aerobes and are dependent upon respiration using oxygen as a terminal electron acceptor to generate adequate ATP and a …
WebMar 2, 2024 · Introduction. Symbiotic nitrogen fixation (SNF) of leguminous crops is a key component of nitrogen (N) management in agricultural systems, with about 4 × 10 7 tons of N added to agricultural systems through SNF each year (Herridge et al., 2008; Li et al., 2015).Compared with industrial N fertilizers, SNF has significant advantages in improving … WebFeb 1, 2012 · Background. Sinorhizobium meliloti is a soil bacterium, known for its capability to establish symbiotic nitrogen fixation (SNF) with leguminous plants such as alfalfa.S. meliloti 1021 is the most extensively studied strain to understand the mechanism of SNF and further to study the legume-microbe interaction.
