To understand how ocean acidification (OA) influences sediment microbial communities, naturally CO2-rich sites are increasingly being used as OA analogues. However, the characterization of these naturally CO2-rich sites is often limited to OA-related variables, neglecting additional environmental variables that may confound OA effects. Here, we used an extensive array of sediment and bottom wat...

Here, we explore if microbial fuel cell (MFC) technology can replace activated sludge processes for secondary wastewater treatment. We will discuss the present limitations and problems of electric current generation when a complex wastewater is treated with a diverse and undefined community of microbes in large-scale systems. These challenges include low coulombic efficiencies, slow kinetic rat...

The main objective of this paper is to study the performance of the various combinations of electrodes which plays an important role in the microbial fuel cells for the generation of electricity. The present work is an experimented investigation concerned with selection of the electrodes for the best performance of a microbial fuel cell. The various combinations of anode/cathode materials like ...

Microbial fuel cell (MFC) involves the bioelectrochemical reaction which produces electricity by the microorganisms. MFC converts the biochemical metabolic energy to electrical energy through microbial catalyst at the anode under anaerobic conditions. It is the apt answer of alternative energy source in recent increasing energy crisis. In microbial fuel cells, bacteria generate electricity by m...

The sediment-water interface of freshwater lakes is characterized by sharp chemical gradients, shaped by the interplay between physical, chemical and microbial processes. As dissolved oxygen is depleted in the uppermost sediment, the availability of alternative electron acceptors, e.g. nitrate and sulfate, becomes the limiting factor. We performed a time series experiment in a mesocosm to simul...
