"Most species of Herbaspirillum are nitrogen-fixing bacteria that are commonly found in the rhizosphere and colonize plants endophytically. They are found in the roots and stems of maize, rice, beans, bananas, sugar cane, pineapple, and other plants and they have been recovered from groundwater and drinking water distribution systems as well (PubMed)."
