WebBiological nitrogen fixation (BNF) is responsible for the recovery of nitrogen in environment. Specific bacteria carry out the fixing of molecular nitrogen (N2) into bioavailable complexes for cellular consumption. N2 is reduced in many electron transfer reactions throughout the process of biological nitrogen fixation, ensuing the production … Biological nitrogen fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by a nitrogenase enzyme. The overall reaction for BNF is: The process is coupled to the hydrolysis of 16 equivalents of ATP and is accompanied by the co-formation of one equivalent of H 2.
