Resumen
"The effect of real dairy wastewater (DWW) additions on the current density generated by a bioanode was evaluated in a half cell configuration under potentiostatic control, thus simulating the anodic chamber of a Microbial Fuel Cell. Low substrate additions increased current density up to 1655 ± 136 mA m−2, forming a two-current peak pattern. Then the system was tested with a casein-lactose synthetic media. A high protein concentration reduced the current density; individual compounds led to the highest current (330.5 mA m−2 with casein; 1276 mA m−2 with lactose). Moreover, the protein reduced the current start up time." "Se evaluó la densidad de corriente de un bioánodo con adiciones de agua residual lacto-alimenticia. A menor volumen de substrato adicionado, se observó mayor producción de densidad de corriente (1655 ± 136 mA m−2), con un patrón de dos picos de corriente. El sistema evaluado con un medio sintético de caseína-lactosa mostró que una alta concentración de proteína afectó negativamente la corriente producida; los componentes individuales generaron los valores más altos de corriente (330.5 mA m−2 con caseína; 1276 mA m−2 con lactosa). Adicionalmente la proteína favoreció el inicio de generación de corriente."
