Abstract:
... We constructed binary and ternary systems between U (VI) and Shewanella putrefaciens, kaolin, and nano-α-Fe₂O₃, and studied the interactions of mixtures in the systems to determine and describe the role of microorganisms in regulating the environmental mobility of U. Shewanella putrefaciens, kaolin, or nano-α-Fe₂O₃ was placed in U (VI) solution to form a binary system. In this system, the adsorpti ...

In order to obtain the chitosan (CS) coatings with excellent physicochemical properties and antibacterial abilities, the CS coatings were modified by in situ modification nano‐CaCO₃ and nano‐TiO₂. The coatings were characterised, and their physicochemical properties were measured. The antibacterial mechanism of the coatings was investigated with the Shewanella putrefaciens and Pseudomonas aerugino ...

Abstract:
... Carbon nanotubes (CNTs) mediation of the reduction of nano goethite (α-FeOOH) by Shewanella putrefaciens CN32 to improve the removal efficiency of tetrabromobisphenol A (TBBPA) was investigated in this study. The results showed that CNTs effectively promoted the biological reduction of α-FeOOH by strengthening the electron transfer process between Shewanella putrefaciens CN32 and α-FeOOH. After α- ...

Abstract:
... Exoelectrogens play the core roles in bioelectrochemical systems (BESs) because of their unique extracellular electron transfer capacity to different electron acceptors. Microbial reduction of azo dyes by exoelectrogens under anaerobic conditions has received great attention because of its eco-friendliness, low cost, and unique extracellular reduction ability. In this work, we unexpectedly found t ...
... Metalworking fluids (MWFs) are essential components for modern metalworking technologies. The volume of world consumption of diluted working solutions exceeds 20 million tons annually. Water miscible MWFs accounts to 90% of the global MWFs demand. Spent MWFs contain toxic xenobiotics and residues of biocides. They are hazardous to the environment and require complex processing and detoxification. ...
