Bacteria of the genus Rhizobium nodulate legumes and are responsible for nitrogen fixation. The energetics of this process are improved if hydrogen uptake ability (Hup) is imparted to the bacteria to recycle some of the hydrogen lost during the nitrogen fixation. Such Hup is observed in a ...
Nitrogen-fixing bacteria examples compriseRhizobium(formerly Agrobacterium), Frankia, Azospirillum, Azoarcus, Herbaspirillum, Cyanobacteria, Rhodobacter, Klebsiella, etc. N-fixing bacteria synthesize the unique nitrogenase enzyme responsible for N fixation. ...
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 is important to reap high yields. Nitrogen-fixing crops and bacteria are popular methods, friendly to farmers and nature.

- Putrefying bacteria are responsible for the decomposition of organic matter, particularly under anaerobic conditions. - They do not play a role in nitrogen fixation. - Therefore, this option is also incorrect. 5. Evaluating Option (d) Denitrifying Bacteria: - Denitrifying bacteria convert nit...
“We thus provide the first indication that purple sulfur bacteria may have been partly responsible for nitrogen fixation in the Proterozoic ocean,” Philippi continued. “Until now, it was generally assumed that cyanobacteria carried out most of the nitrogen fixation then. We show that the role ...
Cell-specific measurements show nitrogen fixation by particle-attached putative non-cyanobacterial diazotrophs in the North Pacific Subtropical Gyre Nitrogen-fixing (diazotrophic) cyanobacteria provide a critical nutrient input to the ocean. Non-cyanobacterial diazotrophs are also thought to contribute, but ...
Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities ...
