Measurement of Cd and Zn content in bacteria supernatants and rinsing solutions. (A) Cd content of singly grown bacterial strains (A–H), as indicated in Table 2 and of the eight selected bacterial strains grown together (Cd+8S). (B) Zn content of singly grown bacterial strains (A–H), as indicated in Table 2 and of the eight selected bacterial strains grown together (Zn+8S). Nut: nutrient solution. Cd+nut and Zn+nut were added as positive control. Data are the mean ±SD (n=3). Differences between means were scored for significance according to the Duncan test. Values sharing a common letter are not significantly different at P <0.05.
