Microfibrillated cellulose (MFC) can be used in many industrial areas such as composites for construction, automotive, furniture and new materials for electronics and pharmaceutical applications as well as thickener in cosmetic products. It can be isolated from different lignocellulosic materials using numerous technologies. In this study, MFC was produced from cocoa pod husk (CPH) substrate in...

The aim of the present study was to construct the eukaryotic expression vector pcDNA3.1/15-PGDH. The vector was used to transfect mouse murine forestomach carcinoma (MFC) cancer cells and observe the effects of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) on the proliferation of MFC. pcDNA3.1/15-PGDH was constructed using gene recombination technology and the vector was used to transfect MFC...

Electrochemical impedance spectroscopy (EIS) was used to study the behavior of a microbial fuel cell (MFC) during initial biofilm growth in an acetate-fed, two-chamber MFC system with ferricyanide in the cathode. EIS experiments were performed both on the full cell (between cathode and anode) as well as on individual electrodes. The Nyquist plots of the EIS data were fitted with an equivalent e...

Due to a growing world population and increasing welfare, energy demand worldwide is increasing. To meet the increasing energy demand in a sustainable way, new technologies are needed. The Plant-Microbial Fuel Cell (P-MFC) is a technology that could produce sustainable bio-electricity and help meeting the increasing energy demand. Power output of the P-MFC, however, needs to be increased to mak...

The extensive use of Cr(VI) in many industries and the disposal of Cr(VI)-containing wastes have resulted in Cr(VI)-induced environmental contamination. Cr(VI) compounds are associated with increased cancer risks; hence, the detection of toxic Cr(VI) compounds is crucial. Various methods have been developed for Cr(VI) measurement, but they are often conducted offsite and cannot provide real-tim...

A microbial fuel cell (MFC) latrine that treats human waste and produces compost and electricity was deployed in Agona Nyakrom, Ghana. After solid wastes were composted, the MFC treated organic matter and nitrogen from the remaining liquid stream. Organic matter was oxidized in the anode by anode-respiring bacteria that transfer electrons to an external circuit, producing electricity, which was...

A single-chamber microbial fuel cell (MFC) was used to reduce 10 chemicals associated with odors by 99.76% (from 422 +/- 23 mug/ml) and three volatile organic acids (acetate, butyrate, and propionate) by >99%. The MFC produced a maximum of 228 mW/m(2) and removed 84% of the organic matter in 260 h. MFCs were therefore effective at both treatment and electricity generation.

Microbial fuel cell (MFC) sensor exhibits attractive prospects for real-time monitoring of nitrate (NO3-) in water, with unique advantages self-powering and simple structure; but its stability sensitivity are unsatisfactory. In an attempt to address the limitations, here we employed open-circuit MFC (O-MFC) NO3- compared a conventional closed-circuit (C-MFC) sensor. The O-MFC was confirmed when...
