New Pseudomonas Study Findings Have Been Reported by Investigators at University of Rennes (Microbial Nitrate Reduction Electro-assisted By Exo-electrogenic Reduction of Dioxygen With a Pseudomonas Dominated Cathodic Biofilm).

Researchers at the University of Rennes in France have conducted a study on Pseudomonas, a type of Gram-Negative Bacteria. They developed a nitrate reducing microbial biocathode using two types of inoculums: a pure culture of Thiobacillus denitrificans and water collected from an artificial wetland. The results showed an increase in nitrate removal efficiency and a correlation between cathode polarization and nitrate remediation. The researchers hypothesize that the improved performance is due to an indirect bioelectro-assistance that creates local anoxic conditions. This research has been peer-reviewed and published in the journal Electrochimica Acta. [Extracted from the article]
