Researchers' Work from National Yunlin University of Science and Technology Focuses on Chalcogens (Effects of mediator producer and dissolved oxygen on electricity generation in a baffled stacking microbial fuel cell treating high strength ...)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Chalcogens. According to news reporting out of Yunlin, Taiwan, by NewsRx editors, research stated, "The effects of Pseudomonas aeruginosa, pyocyanin, and influent dissolved oxygen (DO) on the electricity generation in a baffled stacking microbial fuel cell (MFC) treating high strength molasses wastewater were investigated. The result shows that the influent chemical oxygen demand (COD) of 500-1000 mg l(-1) had the optimal substrate-energy conversion rate."

Our news journalists obtained a quote from the research from the National Yunlin University of Science and Technology, "The addition of a low density of P. aeruginosa (8.2 mg l(-1)) or P. aeruginosa with pyocyanin improved the COD removal and power generation. This improvement could be attributed to the enhancement of electron transfer with the help of redox mediators. Influent DO at a concentration of up to 1.22 mg l(-1) did not inhibit the electricity generation. Large proportions of COD, organic-N and total-N were removed by the MFC. The MFC effluent was highly biodegradable. Denaturing gradient gel electrophoresis analysis shows that the added pyocyanin resided in the MFC for up to 14 days."

According to the news editors, the research concluded: "An analysis of anode voltage reveals that microbial proton transport to the cathode was importantly responsible for the internal resistance."
