Abstract

Quorum-sensing molecules (QSMs) extracted from anaerobic sludge can help to enhance the overall productivity of algal culture, thus diminishing the per unit production cost of algae based-biofuel. In this investigation, QSMs extracted from anaerobic bacterial sludge of microbial fuel cell (MFC) was used to enhance the overall productivity of Chlorella sorokiniana cultivated in a separate bubble column photobioreactor. With the dosage of QSMs, algal biomass productivity and lipid content were increased by 2.25 times and 1.28 times, respectively. Further, lipid extracted biomass of quorum-sensing induced algae (LEB-QSA) was applied in anodic chamber of MFC to function as substrate and mediator, which enhanced the coulombic efficiency of this MFC by 74% as compared to the control MFC operated without LEB-QSA. Thus, this exploration demonstrated successful improvement in the macromolecular properties of algal culture dosed with QSMs and improved performance of MFC with the application of LEB-QSA as mediator and substrate.
