Dissimilatory metal reducing bacteria (DMRB) are capable of extracellular electron transfer (EET) to insoluble oxides, which used as external acceptors by DMRB for their anaerobic respiration. The EET process has important contribution environmental remediation mineral cycling, and bioelectrochemical systems. However, the low efficiency remains be one major bottlenecks its practical applications pollutant degradation. In this work, Shewanella oneidensis MR-1, a model DMRB, was examine...
Chromium is a common heavy metal widely present in aquatic environments. Cost-effective remediation of chromium-contaminated environment can be realized by microbial reduction Cr(VI) to Cr(III). The genus Aeromonas species one such reducers, whose mechanism remains unrevealed and the main factors governing pathways are unknown yet. In this work, performances mechanisms anaerobic hydrophila ATCC 7966 were investigated. This strain exhibited excellent resistance could utilize suite electron...
Azo dyes are a class of recalcitrant organic pollutants causing severe environmental pollution. For their biodecolorization, the azo reductase system was considered as major molecular basis in bacteria. However, intracellular localization limits function for efficient dye decolorization. This limitation may be circumvented by electrochemically active bacteria (EAB) which is capable extracellular respiration. To verify essential role respiration decolorization, Geobacter sulfurreducens PCA,...
Abstract The migration of atomic hydrogen species over heterogeneous catalysts is deemed essential for hydrogenation reactions, a process closely related to the catalyst's functionalities. While surface hydroxyls‐assisted spillover well documented on reducible oxide supports, its effect widely‐used nonreducible especially in electrocatalytic reactions with water as source, remains subject debate. Herein, oxide‐anchored copper single‐atom catalyst (Cu 1 /SiO 2 ) designed and uncover that...
The cross-coupling reactions of 1,1,1-trifluoro-2-iodoethane with aryl and heteroaryl boronic acid esters have been successfully achieved. new protocol allows for a convenient introduction trifluoroethyl groups into variety moieties under mild conditions.
Biofabrication of nanomaterials is currently constrained by a low production efficiency and poor controllability on product quality compared to chemical synthetic routes. In this work, we show an attractive new biosynthesis system break these limitations. A directed selenium-containing nanoparticles in Shewanella oneidensis MR-1 cells, with fine-tuned composition subcellular location, was achieved modifying the extracellular electron transfer chain. By taking advantage its untapped...
A nearly two-octave wide coherent mid-infrared supercontinuum is demonstrated in a dispersion-engineered step-index indium fluoride fiber pumped near 2 µm. The pump source an all-fiber femtosecond laser with 100 fs pulse width, 570 mW average power and 50 MHz repetition rate. spectrum spans from 1.25 µm to 4.6 Numerical modelling of the spectra show good agreement measurements. coherence calculated using numerical model shows high degree across generated bandwidth allowing it be used for...
The extensive use of roxarsone in the poultry and livestock industry has led to increasing arsenic contamination soil aquatic environments. Microbial activity, especially exoelectrogenic bacterium (EEB)-mediated bioreduction, plays important roles such a bioconversion. However, biomolecular-level mechanism behind this process reduction pathways remain largely unclear. Herein, rapid anaerobic by several EEB was explored, degradation were clarified using Shewanella putrefaciens CN32 as model....
Abstract The bioreduction capacity of Cr(VI) by Shewanella is mainly governed its bidirectional extracellular electron transfer (EET). However, the low EET efficiency restricts wider applications in remediation environments contaminated Cr(VI). Cyclic adenosine 3′,5′‐monophosphate (cAMP) commonly exists strains and cAMP–cyclic receptor protein (CRP) system regulates multiple EET‐related pathways. This inspires us to strengthen through elevating intracellular cAMP level strains. In this...
