In many microbial bioreactors, high shear rates result in strong attachment of microbes and dense biofilms. In this study, high shear rates were applied to enrich an anodophilic microbial consortium in a microbial fuel cell (MFC). Enrichment at a shear rate of about 120 s(-1) resulted in the production of a current and power output two to three times higher than those in the case of low shear r...

Cell-surface display is the expression of peptides and proteins on the surface of living cells by fusing them tofunctional components of cells which are exposed to the environment of cells. This strategy can be carriedout using different surface proteins of cells as anchoring motifs and different proteins from different sourcesas a passenger protein. It is a promising strategy...

A new strategy of electrogen immobilization was developed to construct a conductive artificial biofilm (CAB) on an anode of a microbial fuel cell (MFC). The MFCs equipped with an optimized CAB exhibited an eleven fold increase in power output compared with natural biofilms.

introduction: different microbial compounds can induece maturation of dendritic cells (dcs) into dc1 or dc2 .in the present study, we used tumor antigen pulsed dendritic cell that matured with listeria monocytogenes antigen and cholera toxin (ct) in the treatment of a murin model of cancer. material and methods: tumor cells (wehi-164 balb/c derived fibrosarsoma) were injected subcutaneously to ...

Electrochemically active bacteria in a microbial fuel cell (MFC) usually exist as a biofilm attached to an electrode surface. Conventional cyclic voltammetry using potentiostat is considered as a powerful and reliable method to study electrochemical behavior of MFC biofilm. In this paper, we introduce a new approach to evaluate redox behavior of an electro-active MFC biofilm without using a pot...

The rapid development of synthetic biology enables the design, construction and optimization of synthetic microbial consortia to achieve specific functions. In China, the "973" project-"Design and Construction of Microbial Consortia" was funded by the National Basic Research Program of China in January 2014. It was proposed to address the fundamental challenges in engineering natural microbial ...

BACKGROUND The release of antibiotics into aquatic environments has made the treatment of wastewater containing antibiotics a world-wide public health problem. The ability of microbial fuel cells (MFCs) to harvest electricity from organic waste and renewable biomass is attracting increased interest in wastewater treatment. In this paper we investigated the bioelectrochemical response of an elec...
