After reading this article you will learn about the symbiotic and non-symbiotic nitrogen fixing bacteria. Symbiotic N2-Fixing Bacteria: The heterotrophic bacteria that fix di-nitrogen gas (N2) from the atmosphere in plant root nodules (symbiotic bacteria) have a mutually beneficial relationship with their host plants. Legumes (pod-bearing plants such as peas, beans, alfalfa and clovers etc.) had a beneficial effect upon [...]
