Biofilms are assemblages of bacteria embedded within a matrix of extracellular polymeric
substances (EPS) attached to a substratum. The process of biofilm formation is a complex …

The last two decades have seen geomicrobiology evolve into a broad field encompassing a
wide range of environmentally significant processes such as proton and metal adsorption …

This work was conducted to study the effect of soil pH (4.0, 6.0, and 8.0) on the transport,
fractionation, and oxidation of trivalent chromium [Cr (III)]. Variation in pH altered soil …

To clarify the adsorption behaviors of typical heavy metals onto sludge extracellular
polymeric substances (EPS), the adsorption capacities and mechanisms, as well as the …

Chromium (Cr) is mainly found in the form of organic-Cr (III) complexes in the natural
environment and industrial waste. The widespread existence of composite contaminants …

Chromate (Cr (VI)), as one of ubiquitous contaminants in groundwater, has posed a major
threat to public health and ecological environment. Although various electron donors (eg …

The fate of chromium (Cr)–a redox sensitive metal–in surface sediments is closely linked to
early diagenetic processes. This review summarizes the main redox pathways that have …

Laboratory batch and column experiments were conducted to investigate the role of
microbial exudates, eg, exopolymeric substance (EPS) and alginic acid, on microbial Cr (VI) …

Metals as a resource are depleting, and on another side, it fetches serious environmental
pollution causing a threat to human health and ecosystem. The heavy metal accumulation …

Laboratory batch and column experiments, in conjunction with geochemical calculations
and spectroscopic analysis, were performed to better understand reaction mechanisms and …
