L. Lactis Subsp. Lactis of Cheese Origin Based Microbial Fuel Cell

Abstract

In this work, Lactococcus lactis subsp. lactis DLP27 (L .lactis) strain isolated from a traditional Turkish raw milk cheese, Divle Obruk Cheese, was used as a biocatalyst on the bioanode combined with a platinum cathode to fabricate a Nafion membrane based double compartment microbial fuel cell (MFC). Graphene-gold-platinum hybrid nanomaterial was used as modifier in L. lactis immobilized carbon felt based bioanode. Developed Nafion membrane based double compartment MFC characteristics were inspected by using optimized bioanode. In consequence, an open-circuit voltage of 0.282 V, a maximum current density of 59.52 mu A/cm(2) and a maximum power density of 2.12 mu W/cm(2) were achieved with excellent lifetime of 49 days with developed MFC system.
