Abstract

In recent years, aluminum enrichment in soils is exacerbated. The amount of aluminum exchange in acidic soils directly affects the level of soil acidification. Aluminum toxicity-neutralizing capabilities of the microorganisms that have survived under the aluminum toxicity selection determine the harmfulness of aluminum toxicity in soils. Aluminum-tolerant microorganisms, especially aluminum-tolerant bacteria, are ideal for the study of aluminum-tolerance mechanisms. There are not many types of aluminum-tolerant bacteria. In acid soils, fungi are more tolerant to aluminum than bacteria. In addition, the isolation of aluminum-tolerant bacteria is more difficult. Thus, the mechanistic study of aluminum tolerance progressed very slowly. In this study, we isolated a bacteria strain A1 that is highly aluminum tolerant. It tolerated Al3+ at the concentration of 10 mmol/L. This strain was identified as Citrobacter sp., and its capability and features of aluminum tolerance were investigated. Our study provided resource and theoretical basis for the application of aluminum-tolerant bacteria in soils.
