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...

Remarkably, many bacteria live and thrive in the earth’s subsurface by respiring extracellular insoluble minerals. Okamato et al. (1) in PNAS report how this process may be accelerated by the presence of flavins that bind as cofactors to electron transport proteins on the cell surface that are key to extracellular mineral respiration. Humans obtain the energy needed for life by respiring oxygen...

Microbial fuel cells utilises waste carbohydrates as fuel. It has the property of not utilising a catalyst or proton exchange membrane and it is thus eco-friendly for treating wastes. Biological fuel cell converts chemical energy directly into electrical energy. They are in light because they act in very mild conditions such as ambient temperature, pressure, and inexpensive catalysts i.e. micro...

A nested PCR primed by four degenerate oligonucleotides was developed for the specific amplification of sequences from the napA gene encoding the periplasmic nitrate reductase. This approach was used to amplify fragments of the napA gene from 10 Pseudomonas species and one Moraxella sp., previously shown to be able to express the periplasmic nitrate reductase activity, from Rhodobacter capsulat...

In this study, a bioremediation approach was evaluated for the decontamination of an aquifer affected by release organohalides industrial landfill. After preliminary physicochemical and microbiological characterization landfill groundwater, stimulation natural organohalide respiration addition reducing substrate (i.e., molasse) tested both at microcosm field scales, placement anaerobic permeabl...

The γ isomer of hexachlorocyclohexane (HCH), also known as lindane, is a carcinogenic persistent organic pollutant. Lindane was used worldwide an agricultural insecticide. Legacy soil and groundwater contamination with lindane other HCH isomers still big concern. biotic reductive dechlorination to nondesirable toxic lower chlorinated compounds such monochlorobenzene (MCB) benzene, among others,...
