荧光假单胞菌和根瘤菌在确定的培养基中对铝有相似的反应。DNA是Al在根瘤菌中的作用位点，以及Al在实验室介质中的诱变效应的证据，进行了综述。初步数据表明，铝耐受性在这些细菌中不是质粒携带的性状。本文讨论了铝在土壤细菌生态中的可能作用，并与细菌代谢引起的土壤pH变化对铝的中和作用有关。
Pseudomonas fluorescensandRhizobiumshowed similar responses to Al in defined medium. Evidence that DNA is a site of action of Al inRhizobium, and for mutagenic effects of Al in laboratory media, is reviewed. Preliminary data are presented which indicate that Al tolerance is not a plasmid-borne trait in these bacteria. The possible role of Al in the ecology of bacteria in soil is discussed in relation to the neutralisation of Al brought about by changes in soil pH by bacterial metabolism.
