Wastewater has high potential as an energy source. Therefore, it is important to recover even the smallest part of this energy, e.g., in microbial fuel cells (MFCs). The obtained electricity production depends on process rate electrodes. In MFC, microorganisms are catalyst, and cathode usually made carbon material (e.g., with addition Pt). To increase MFC efficiency (and reduce costs by reducin...

The minimal fungicidal concentration (MFC) of dihydrosphingosine (DHS), phytosphingosine (PHS), and five short-chain DHS derivatives was determined for Candida albicans and Candida glabrata. In this respect, a C15- and a C17-homologue of DHS showed a 2- to 10-fold decreased MFC as compared to native DHS (i.e. C18-DHS). DHS derivatives that were active, that is, comprising 12, 15, 17, or 18 carb...

Microbial fuel cells (MFCs) represent a clean and renewable energy resource. To date, power generation in MFCs is severely limited. In order to improve performance, a wide range of techniques have been utilised for a fundamental scientific understanding of the components and processes and also to investigate MFC performance bottlenecks. In this tutorial review, we discuss the electrochemical/el...

Plant microbial fuel cell (Plant-MFC) is an emerging technology that uses the metabolic activity of electrochemically active bacteria (EABs) to continue production bioelectricity. Since its invention and date, great efforts have been made for application both in real-time large-scale. However, construction platforms or systems automatic voltage monitoring has insufficiently studied. Therefore, ...

We present a broadband single-mode bi-conical microfiber coupler (MFC) with a specifically designed transition region that effectively suppresses any higher-order modes present at the input fiber and provides efficient power splitting into the fundamental mode at the two output ports. As a practical example, single-mode 3-dB splitting operation over a broad spectral window (400 approximately 17...

This paper describes the development of a microbial fuel cell (MFC) for electricity production from cellulose that is based on mixed culture of rumen bacteria in vitro. The fibrolytic bacteria isolated from rumen fluid were used in anode compartment of MFC, which can release glucose up to 15 g/L from carboxymethyl cellulose (CMC). At the same time, the maximum power density of 100.60mWm was gen...

A microbial electrolysis cell (MEC) was powered by a capacitor based energy storage circuit using energy from a microbial fuel cell (MFC) to increase MEC hydrogen production rates compared to that possible by the MFC alone. To prevent voltage reversal, MFCs charged the capacitors in a parallel configuration, and then the capacitors were discharged in series to boost the voltage that was used to...
