摘要：This study determined the cadmium and lead (Cd and Pb) biosorption of two bacterial strains identified with molecular techniques as Pseudomonas aeruginosa and Enterobacter cloacae . These species were isolated from domestic wastewater and adapted to a maximum of 2.83 and 17.4 mg/L of Cd and Pb, respectively. Cd sorption by both strains, determined by atomic absorption spectrophotometry, ranged from 14.4 to 16.5 %. However, the difference between strains was not significant. P. aeruginosa and E. cloacae were comparatively more efficient in the sorption of Pb (82.47and 72.16 % respectively) than for Cd. The amount of Pb absorbed by the bacterial biomass was significantly higher in P. aeruginosa than in E. cloacae cultures.
