The use of microbial fuel cells (MFCs) is quickly spreading in the fields bioenergy generation and wastewater treatment, as well biosynthesis valuable compounds for electrolysis (MECs). MFCs MECs have not been able to penetrate market economic feasibility lost when their performances are boosted by nanomaterials. nanoparticles used realize or decorate components (electrodes membrane) expensive ...

The nematode Caenorhabditis elegans possesses six morphologically similar neurons that are responsible for sensing gentle touch to the body. Previous genetic studies identified genes that are necessary for the production and differentiation of these touch cells. In particular, unc-86 encodes a POU-type homeodomain protein needed for the production of the touch cells, while mec-3 encodes a LIM-t...

objective: e-cadherin is a classic cadherin that plays a key role in epithelial cell adhesion. this protein is being referred to as the suppressor of proliferation and invasion. limited studies have investigated e-cadherin expression in salivary gland neoplasms. this study sought to assess the expression of e-cadherin and its possible role in progression and invasion of salivary gland neoplasms...

We present a study on a microbial electrolysis cell with methanogenic microorganisms adapted to reduce CO2 to CH4 with the direct injection of electrons and without the artificial addition of H2 or an additional carbon source except gaseous CO2 . This is a new approach in comparison to previous work in which both bicarbonate and gaseous CO2 served as the carbon source. The methanogens used are ...

Harnessing, and understanding the mechanisms of growth and activity of, biofilms of electroactive bacteria (EAB) on solid electrodes is of increasing interest, for application to microbial fuel and electrolysis cells. Microbial electrochemical cell technology can be used to generate electricity, or higher value chemicals, from organic waste. The capability of biofilms of electroactive bacteria ...

The microbial electrochemical cell (MEC) is a promising waste treatment technology to accomplish simultaneous alternative energy production and degradation of organic matters. Potato pulp waste (PPW) from a potato processing plant contains a large amount of carbohydrates that need be degradated before discharge into the environment. Here, we describe electricity generation in singlechamber micr...

Petroleum industries are large water consumers and generate a lot of wastewater at various stages industrial operations. Wastewater from the petroleum contain recalcitrant pollutants such as hydrocarbons that present in high concentrations, dissolved solids sulfur compounds can pose potential environmental threat. Bioelectrochemical systems (BESs) known to be sustainable processes treat kinds w...

The aim of this work is to study the degradation and mineralization of antibiotic ofloxacin in aqueous medium using the Electro-Fenton method as advanced oxidation technology. In this context, Pt/carbon-felt cell was used to investigate the influence of various parameters including initial pH, different supporting electrolytes, different metal ions as a catalyst and antibiotic concentration ove...

Bioelectrochemical systems (BESs) were first operated in microbial fuel cell mode for recovering Cu(II), and then shifted to microbial electrolysis cells for Cd(II) reduction on the same cathodes of titanium sheet (TS), nickel foam (NF) or carbon cloth (CC). Cu(II) reduction was similar to all materials (4.79-4.88mg/Lh) whereas CC exhibited the best Cd(II) reduction (5.86±0.25mg/Lh) and hydroge...
