Response of Concentration and Composition of Essential oil of Coriander (Coriandrum sativum L.) to Cattle manure and Nitrogen fixing bacteria
In order to study the response of concentration and composition of essential oil of coriander (Coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle...
متن کاملFerredoxins from Nitrogen-Fixing Bacteria
Two ferredoxins have been purified from N2-fixing Mycobacterium flavum. Ferredoxin I had a minimum molecular weight (by amino acid analysis) of 11 230 and contained 7.4 mol Fe and 7.0 mol S2per mol. The ratio of the absorbance at 400 nm to that at 275 nm was 0.7. Ferredoxin I1 had a minimum molecular weight of 13478 and contained 3.4 mol Fe and 3.2 mol S2per mol. The ratio of the absorbance at ...
متن کاملAmmonia Accumulation of Novel Nitrogen-Fixing Bacteria
Nitrogen is an essential element for many biological processes, including those occurring in plants (Ogura et al., 2006). Despite the abundance of atmospheric nitrogen, production of nitrogen fertilisers by the Harber–Bosch process is increasing annually due to the deficiency of ammonia produced by biological nitrogen fixation—the enzyme-catalyzed reduction of nitrogen gas (N2). Concern over ‘g...
متن کاملFate of Nitrogen-15 Enriched Ammonium Nitrate Applied to Corn
Nitrogen utilization by corn (Zea mays L.) is influenced by the form of inorganic N present in the root zone. A field experiment was conducted on Enon sandy loam (fine, mixed, thermic Ultic Hapludalf) to determine N use efficiency and its partitioning in various plant parts of corn. Ammonium nitrate labeled either as NH4-N or NO3-N and applied at 50, 100, or 200 kg N ha" was evaluated. Microplo...
متن کاملUse of nitrogen-fixing bacteria to improve agricultural productivity
Nitrogen-fixing, plant-growth promoting bacteria are arguably the biotechnological tool of highest potential to improve agricultural productivity in short term. Nitrogen fixation and phytohormone production by these bacteria have been considered the most important factors for plant growth promotion. However, the underlying mechanisms responsible for productivity increases by associative bacteri...
