Functional group diversity for the adsorption of lead(Pb) to bacterial cells and extracellular polymeric substances

Chenchen Qu et al.

Summary: Bacteria and their secreted EPS have the ability to immobilize heavy metals, and this study reveals the functional diversity and adsorption mechanisms of Pb onto bacteria and EPS in detail. The partitioning of Pb to functional groups differs between bacterial strains, EPS fractions, and Pb concentrations, and the adsorption occurs through a universal entropy increase and inner-sphere complexation mechanism.

Ferrihydrite-organo composites are a suitable analog for predicting Cd(II)- As(V) coexistence behaviors at the soil solid-liquid interfaces*

Huihui Du et al.

Summary: Research findings suggest that the coadsorption behavior of Cd-As on organomineral composites differs from that on pure minerals, and the presence of organics significantly affects the speciation and distribution of metals (loids). Organomineral composites are a more suitable analog than pure mineral phases to predict the mobility and fate of Cd-As in natural environments.

Contribution of pristine and reduced microbial extracellular polymeric substances of different sources to Cu(II) reduction

Hang Xu et al.

Summary: This study highlights the significant role of microbial EPS as reducing agents and electron transfer mediators for cupric reduction and cuprous formation in natural environments. EPS from different microbial species showed varied electron transfer ability, with c-type cytochromes playing a major role in copper transformation for Shewanella oneidensis MR-1 EPS, while functional groups like phenolic and amide dominated Cu(II) reduction for Bacillus subtilis and Saccharomyces cerevisiae EPS.

Recent advances in the application of nanomaterials for the remediation of arsenic-contaminated water and soil

Leila Alidokht et al.

Summary: This review focuses on the recent advances in the use of nanotechnologies and nanocomposites for remediation of arsenic-contaminated water and soil. Various engineered organic/inorganic nanocomposites with exceptional physical-chemical properties have been developed, showing great potential for As removal or immobilization in contaminated sites. Emerging approaches include the development of bio-nanocomposites with both oxidative and adsorptive capacities, while gaps in research and directions for future studies have been identified.
