Nitrogen fixation has been enhanced by deletion of nifL and by bringing nifA under the control of a constitutive promoter, resulting in a strain that continues to fix nitrogen in presence of urea fertilizer. and S. Ayyappan, 1998. USA.gov. Predominant species used as biofertilizers are Azotobacter chroococcum and Aztobacter vinelandii. This video is unavailable. COVID-19 is an emerging, rapidly evolving situation. Biofertilizer is a biotic constituent of specific microbial cells which when applied, stimulates plant growth by accelerating the rate of nutrient release through nitrogen fixation, phosphorus cycle etc [1]. Azotobacter chroococcum as a potentially useful bacterial biofertilizer for cotton (Gossypium hirsutum): Effect in reducing N fertilization. Phosphorus. The commercial history of biofertilizer start with the introduction of “Nitragin” by Nobbe and Hiltner, a laboratory culture of Rhizobia in 1895, followed by discovery of Azotobacter and then blue green algae (Ghosh, 2004; Mazid et al., 2011; Mazid and Khan, 2015; Das et al., 2015). Keywords: Broadly, biofertilizer constitutes of living organisms which include mycorrhizal fungi, blue-green algae, and bacteria. In addition to the structural genes of the enzyme nitrogenase and of other accessory proteins, A. vinelandii chromosomes contain the regulatory genes nifL and nifA. Azotobacters have been used as biofertilizer since more than a century. NifL on activation by oxygen or ammonium, interacts with NifA and neutralizes it. GreenMax AgroTech is capable to produce ten tonnes of technical grade Azotobacter chrococcum per day. Azotobacteris one of the most important microorganisms, which is widely used as biofertilizer (Pereira and Shetty, 1987).
