Is géineas é Asótabaictéar de bhaictéir gluaisteacha, ubhchruthacha nó sféarúla de ghnáth a fhoirmíonn cisteanna le ballaí tiubha agus a d’fhéadfadh méideanna móra slaim capsúiligh a tháirgeadh. Is miocróib ithreacha aeróbacha beo iad, a bhfuil ról tábhachtach acu sa timthriall nítrigine sa nádúr, i bhfosúchán nítrigine atmaisféaraí, atá dorochtana do phlandaí, agus á scaoileadh i bhfoirm iain amóiniam san ithir. Chomh maith le bheith ina samhailorgánach chun staidéar a dhéanamh ar diasótróip, úsáideann daoine é chun bithleasacháin, breiseáin, agus roinnt bithpholaiméirí a tháirgeadh. D'aimsigh an micribhitheolaí agus luibheolaí Dúitseach Martinus Beijerinck an chéad ionadaí den ghéineas, Azotobacter chroococcum, i 1901. Is baictéir Ghram-dhiúltacha an speiceas Azotobacter a fhaightear in ithreacha neodracha agus alcaileacha,^[1]^[2] in uisce, agus i gcomhar le roinnt plandaí.^[3]^[4]
