Hello, Anthony. Great question! While I agree with Peter's answer, if it was my question, I woukd be looking for a more specific answer. Diazotrophs is the name for all nitrogen fixing bacteria in general. However, there are different types. One of the most common nitrogen fixers are the legume family. The symbiotic bacteria that lives with legumes ( Most frequently peanuts, beans, and peas) is called Rhizobium. There are other nitrogen fixing bacteria, such as the Frankia bacteria, which are present on plants that are members of the rose, birch, and bayberry families. Azospirillum is symbiotic with cereal grasses. One of the most common nitrogen fixing bacteria that does not have a symbiotic relationships is cyanobacteria, or algae found in the ocean.
