AMVAC, Azotic North America Collaborate to Develop, Commercialize N-Fixation Product Envita For SIMPAS-applied Solutions.

Bacteria engineered to excrete high concentrations of ammonia could help reduce the reliance on synthetic fertilizers and the nutrient loss associated with them, according to new research from Washington State University.

New studies confirm that nitrogen-fixing bacteria can contribute as much as 30% of the N requirement of a corn crop, say researchers from AgriThority.

New U.S. patents will allow the UK-based company to expand the availability of Envita, an environmentally friendly nitrogen-fixing bacteria.

In many nitrogen-fixing bacteria, a protein called RirA plays a key role in regulating iron by sensing high levels of the metal and shutting down the production of proteins that bring in more iron. RirA contains a cluster of four iron and four sulfur atoms, which acts as a sensor for iron availability. But until now, exactly how this cluster structure detects iron levels in a cell was unclear, says the University of East Anglia.
