Nitrogen is inaccessible to most living organisms as a gas (N2). Nitrogen gas must first be "fixed" by soil bacteria living in association with the roots of particular plant like legumes, clover, alfalfa, soybeans, peas, peanuts, and beans.
Living on nodules around the roots of legumes, the bacteria chemically combine nitrogen in the air to form nitrates (NO3) and ammonia (NH3) making it available to plants.
This is part of the Nitrogen cycle.
Examples:
Diazotrophs
Cyanobacteria
Azotobacteraceae
Rhizobia
Frankia
