摘要：

This paper discusses the potential of Pseudomonas aeruginosa in treating aluminium containing wastewater and aluminium recovery potential from the produced biomass. The species of P. aeruginosa was isolated from aluminium contaminated site. This isolate had characteristics of acid resistant up to pH 5 and aluminium resistant up to 250 mg/L. Aluminium removal test showed that the isolated P. aeruginosa removed up to 46.08 +/- 1.95% of 50mg/L aluminium initial concentration from wastewater. The potential of aluminium recovered from cells biomass reached 34.2 +/- 4.25% with centrifugation and 16.8 +/- 3.02% without centrifugation. Further application in real condition should accommodate the settling velocity of bacteria and aluminium precipitation during treatment, in order to achieve high removal and recovery efficiency.
