Bacteria Supported on Carbon-Coated Monoliths for Water Denitrification

C, 2020
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 ...
