摘要：

Gram-positive and Gram-negative bacteria were isolated from activated sludge and used to evaluate differences in cadmium biosorption. Gram-positive bacteria exhibited approximately 20% more cadmium biosorption at 30°C and pH 6.6 than Gram-negatives. Biosorption was largely passive in both cases, although metabolic uptake appeared to occur to a higher extent with Gram-positive bacteria. © 1990 Kluwer Academic Publishers.
