Escherichia coli bacteria were grown inside the channels of cordierite monoliths previously coated with a very good adhered carbon layer. These monolithic structures were tested at room temperature for the nitrate elimination of water solutions working as a batch monolithic bioreactor and showed very good results, as 100% of the nitrates and nitrites were completely removed in the used experimental conditions. Different rate flows of bacteria growth and nitrate elimination were studied, showing that the higher the flow velocity, the faster the nitrate elimination. Finally, the reproducibility tests confirmed the good performance of the proposed bioreactor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
