• EPS-C, N, P preferentially retained during adsorption and coprecipitation with Fh. EPS mass uptake selective fractionation opposite for the two formation pathways. Proteins acidic polysaccharides selectively in complexes. Lipids polysaccharide components coprecipitates. Differential sorption process of Fh revealed by 2D-COS-FTIR. Recent work shows that microbially-derived compounds constitute...

The significant accumulation of Pb from anthropogenic activities threatens environmental ecosystems. In the environment, iron oxides are one main carriers Pb. Thus, redox cycling oxides, which is due to biotic and abiotic pathways, leads their dissolution or transformation, controls fate However, a knowledge gap exists on bioreduction in Pb-bearing ferrihydrites, secondary-mineral precipitation...
