| Abstract: | Summary The distribution of chromium in subcellular components was examined with a fresh and starved denitrifying consortium by performing Cr+6 equilibration and cell fractionation tests. The cell wall fraction of 50 day starved cells adsorbed approximately 100% more chromium than did the cell wall fraction in fresh cells. The soluble fraction of 50 day old cells showed less affinity for chromium than fresh cells. |
