White-rot fungus is able to secrete laccase, which can reduce O2 to H2O and has been widely used in enzymatic fuel cells. In this work, a strain of white-rot fungus, Coriolus versicolor, is inoculated in the cathodic chamber of a microbial fuel cell (MFC) to improve cathode reduction efficiency...

Combination of toxic contaminant degradation with hydrogen production has been regarded as a promising but challenging approach in wastewater treatment. In this work, the effects of benzoate concentration, pH and type of nitrogen source on photo-hydrogen production from benzoate by...

Conversion of organic matter to hydrogen in a microbial electrolysis cell (MEC) is one of promising ways for hydrogen generation. However, the lack of efficient and cost-effective cathode catalysts and the need of additional electricity input make it less attractive. To resolve these problems,...

The biogas upgrading is necessary for its application, and alkali CO2 adsorption is one efficient method. In this study, a coupled system, bipolar membrane electrodialysis (BPMED)–microbial fuel cell (MFC), was proposed for alkali production, which could also realize electricity in situ...

Hydrogen supersaturation in extreme-thermophilic (70°C) mixed culture fermentation (MCF) was demonstrated for the first time by membrane inlet mass spectrometry. It was found that hydrogen supersaturation ratio (RH2) increased dramatically (from 1.0 to 20.6) when H2 partial pressure (PH2) was...

Brewery wastewater was converted H2 by anaerobic sludge in batch experiments. A three-factor three-level experimental design of Box-Behnken method was adopted to find the optimum H2 production conditions. The effects of three major influence factors, temperature, pH and brewery wastewater...

The stability of biological H2 production and microbial diversity by anaerobic sludge treated chloroform with different concentrations were investigated in this work. Taking into account the cumulative H2 production, H2 percentage, maximum H2 production rate, H2 yield and substrate utilization...

Digester sludge and rumen fluid were explored as the inoculum sources of anaerobic reactors fed with aquatic plants. Methane and volatile fatty acid were both expressed in terms of chemical oxygen demand (COD) in this study. A higher product yield of 464.3 g COD/g total solid (TS) was achieved...

In this study, the mechanisms of anaerobic digestibility of cattail improved by microwave irradiation pretreatment were explored. Both Box–Behnken design and response surface methodology (RSM) were used to optimize the microwave irradiation pretreatment with regard to chemical oxygen demand...

Microbial fuel cell (MFC) is a device that transforms chemical energy in wastewater into electricity, and its performance is influenced by multi-variables. Mathematic modeling approach could be a useful alternative to design and optimize such a complex system for power generation and wastewater...
