abstract: For all living organisms, nitrogen is an essential element, while being the most limiting
in ecosystems and for crop production. Despite the significant contribution of synthetic fertilizers,
nitrogen requirements for food production increase from year to year, while the overuse of
agrochemicals compromise soil health and agricultural sustainability. One alternative to overcome
this problem is biological nitrogen fixation (BNF). Indeed, more than 60% of the fixed N on Earth
results from BNF. Therefore, optimizing BNF in agriculture is more and more urgent to help meet
the demand of the food production needs for the growing world population. This optimization
will require a good knowledge of the diversity of nitrogen-fixing microorganisms, the mechanisms
of fixation, and the selection and formulation of efficient N-fixing microorganisms as biofertilizers.
Good understanding of BNF process may allow the transfer of this ability to other non-fixing
microorganisms or to non-leguminous plants with high added value. This minireview covers a
brief history on BNF, cycle and mechanisms of nitrogen fixation, biofertilizers market value, and use
of biofertilizers in agriculture. The minireview focuses particularly on some of the most effective
microbial products marketed to date, their efficiency, and success-limiting in agriculture. It also
highlights opportunities and difficulties of transferring nitrogen fixation capacity in cereals.
