摘要

Pseudomonas fluorescens and Rhizobium showed similar responses to Al in defined medium. Evidence that DNA is a site of action of Al in Rhizobium, 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 [References: 44]
