Rhizobium

Rhizobium er ættkvísl Gram-neikvæðra jarðvegs baktería sem binda nítrógen. Rhizobium mynda innanfrumusamlíf í sambandi við rætur ertuættar og Parasponia.

Bakteríurnar búa í plöntufrumum í rótarhnýðum þar sem þau umbreyta nitri í lofti í ammoníak og gefa af sér nitursambönd svo sem glútamín eða ureide til plöntunnar. Á móti veitir plantan bakteríunum lífræn efni sem hún hefur myndað með ljóstillífun.. Þetta er gagnkvæmt hagkvæmt samlífi sem er einkennandi fyrir Rhizobium ættkvíslina.

Saga

Beijerinck í Niðurlöndum var fyrstur til að einangra og rækta örveru úr rótum ertuplantna 1888. Hann nefndi hana Bacillus radicicola, og er hún nú staðsett í Bergey's Manual of Determinative Bacteriology undir ættkvíslinni Rhizobium.
