Soluble Extracellular Polymeric Substances Produced by and : Biochemical Characterization and Assessment of Their Cadmium and Lead Sorption Abilities.

In the present study, the potential of lead and cadmium removal by the extracellular polymeric substances (EPS) produced from and were investigated. Carbohydrates were the dominant components of EPS from both analyzed species. The contents of reducing sugars, uronic acids, and amino acids were higher in EPS synthesized than in EPS from .

Physicochemical factors affecting flocculating properties of the proteoglycan isolated from Rhodococcus opacus.

The water-soluble fraction of proteoglycan R-89 isolated from the Rhodococcus opacus FCL89 and composed of 64.6% polysaccharide and 9.44% protein has been studied as regards its flocculating activity.

Studies of cadmium(II), lead(II), nickel(II), cobalt(II) and chromium(VI) sorption on extracellular polymeric substances produced by Rhodococcus opacus and Rhodococcus rhodochrous.

The adsorption of Cd(II), Pb(II), Ni(II), Co(II) and Cr(VI) ions on the extracellular polymeric substances (EPS) obtained from bacterial strain Rhodococcus opacus and Rhodococcus rhodochrous was investigated by the static sorption method. Influence of pH, time and temperature were studied. It was found that the influence of the pH value and time of adsorption depends on the type of adsorbed ions.
