Abstract Long-distance extracellular electron transfer has been observed in Gram-negative bacteria and plays roles both natural engineering processes. The can be mediated by conductive protein appendages (in short unicellular such as Geobacter species) or cell envelopes filamentous multicellular cable bacteria). Here we show that Lysinibacillus varians GY32, a Gram-positive bacterium, is capable of bidirectional transfer. In microbial fuel cells, L. form centimetre-range cellular networks...
A highly efficient dye-decolorizing bacterium, strain S12 T , was isolated from activated sludge of a textile-printing waste-water treatment plant in Guangzhou, China. The cells were Gram-negative and motile by means single polar flagellum. capable anaerobic growth either fermentation glucose or respiration utilized variety electron acceptors, including nitrate, iron oxide thiosulfate. physiological properties, tested using the Biolog GN2 system, similar to those genus Shewanella . Analysis...
ABSTRACT The ability of Shewanella decolorationis S12 to obtain energy for growth by coupling the oxidation various electron donors dissimilatory azoreduction was investigated. This microorganism can reduce a variety azo dyes use formate, lactate, pyruvate, or H 2 as donor. Furthermore, strain grew maximal density 3.0 × 10 7 cells per ml after compete reduction 2.0 mM amaranth in defined medium. accompanied stoichiometric consumption 4.0 formate over time when and were supplied sole acceptor...
Bacterioplankton community compositions in the Dongjiang River were characterized using denaturing gradient gel electrophoresis (DGGE) and 16S rRNA gene clone library construction. Water samples nine different sites taken along mainstem three tributaries. In total, 24 bands from DGGE gels 406 clones libraries selected sequenced, subsequently analyzed for bacterial diversity composition of those microbial communities. Bacterial sequences freshwater bacteria exhibited board phylogenetic...
A high number of aromatic compounds that have been released into aquatic ecosystems accumulated in sediment because their low solubility and hydrophobicity, causing significant hazards to the environment human health. Since nitrate is an essential nitrogen component a more thermodynamically favorable electron acceptor for anaerobic respiration, nitrate-based bioremediation has applied aromatic-contaminated sediments. However, few studies focused on response aromatic-degrading microbial...
<bold>MPT-Cy2</bold>exhibited excellent selectivity and sensitivity toward ˙OH over other ROS showed a high potential for the imaging of endogenous in living cells various types bacteria.
The aim of this study was to characterize anaerobic ammonium oxidation (anammox) community in sediments the Dongjiang River, a drinking water source Hong Kong.The diversity and distribution anammox were investigated based on comparative analyses 16S rRNA hydrazine (hzo) genes bacteria. Candidatus Brocadia two new bacterial clusters detected phylogenetic analysis genes. In contrast, targeting hzo indicated presence only Jettenia with four different clusters. It found that sequence diversities...
OVERVIEW: Microbial fuel cells (MFCs) are an emerging technology which directly converts chemical energy stored in organic matter to electricity. Driven by the increasing concern over energy–climate crisis and environment pollution, MFCs have been developed rapidly past decade. Currently, making challenging step from laboratory practical application. This paper focuses on MFC patents applications of MFCs. IMPACT: make it possible exploit bio-electricity wastes with a higher transforming...
Polybrominated diphenyl ethers (PBDEs) can be reductively degraded by microorganisms under anaerobic conditions. However, little is known about the effect of electron donors on microbial communities involved in PBDEs degradation. Here we employed 454 Titanium pyrosequencing to examine phylogenetic diversity, composition, structure and dynamics from microcosms conditions different donor amendments. The community structures each five alternate enrichments were significantly shifted comparison...
Bacterial respiration is an essential driving force in biogeochemical cycling and bioremediation processes. Electron acceptors respired by bacteria often have solid soluble forms that typically coexist the environment. It important to understand how sessile attached electron respond ambient alternative acceptors. Microbial fuel cells (MFCs) provide a useful tool investigate this interaction. In MFCs with Shewanella decolorationis, azo dye was used as acceptor anode chamber. Different...
Water quality ranks the most vital criterion for rivers serving as drinking water sources, which periodically changes over seasons. Such fluctuation is believed associated with state shifts of bacterial community within. To date, seasonality effects on bacterioplankton patterns in large sources however, are still poorly understood. Here we investigated intra-annual structure Dongjiang River, a source Hong Kong, using high-throughput pyrosequencing concert geochemical property measurements...
Direct visualization evidence is important for understanding the microbial degradation mechanisms. To track pathways of azo dyes with different polar characterizations, sensors based on fluorescence resonance energy transfer (FRET) from 1,8-naphthalimide to were synthesized, in which quenched will recover when bond was cleaved. In living cells, sensor-tracking experiment showed that low polarity and hydrophobic dye can be taken up into cells reduced inside whereas high hydrophilic only...
