To study the effect of glucose feeding rate for sustainable voltage generation from microbial fuel cell containing wastewaters

Abstract

The sustainable voltage generation was extensively experimented through semi batch using isolated pure microorganism. Though higher voltage generation of 911 mV can be possible through optimisation of process parameters by batch fermentation, however, sustainable power generation was not found in batch process. Therefore, the potential influence of several parameters for voltage generation was addressed by semi continuous fermentation process. In this present work sustainable voltage generation (550 mV) was achieved through fed batch mode when initial glucose was kept 8 g/L in the production medium. However, 18 g/L of glucose (25 ml) was consecutively fed at interval of 72 and 108 h during semi continuous fermentation.
