There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic) and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What is the advantage of using legumes as a cover crop in agricultural systems? A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen.
