“…Continuous addition of inoculums every twenty-four hour as was ne in this study, did not affect the generation of bioelectricity but when yeasts were combined in a consortium, there was a synergetic effects among the strains of yeast for bioelectricity generation, it was observed that the synergetic effect depends on the types of yeast combined together Result obtained in this study on the effect of different catholyte materials (Methylene blue, neutral red and potassium ferric cyanide) on the rate of generation of electricity show that there is no significant difference among them. However, Gunawardena et al (2008) observed improved performance in the rate of electricity generation when Methylene blue and potassium ferric cyanide were used as electron mediators, generating an open circuit voltage of 383.6 ±1.5mV. This result indicated that yeast can generate bioelectricity like others prokaryotes but they generated better when used with catholyte such as Neutral red which serves as an electron acceptor in the cathode.…”

Power supply has remained a challeng issue in developing coutries. The aim of this study was to evaluate the potentials of selected yeast species for bioelectricity generation. Different yeast species were isolated from cassava wastewater, whey wastewater, human urine, and rabbit dung using the spread plate method. These isolates were identified using analytical profile index (API). Results obtained revealed the identity of the isolated yeast species as Candida famata, Candida hellenical. Candida tropicalis and Saccharomyces cerevisia (using API method).The isolated yeast species were used singly, and as a consortium for bioelectricity generation, and yeast in continuous mode. The same wastes as used for the isolation process were evaluated as possible substrates for the generation of bioelectricity. Out of the four wastes used, cassava processing wastewater gave the highest bioelectricity potential and was subsequently used as substrate for further study. Saccharomyces cerevisiae elicited the highest electricity generation when the four yeast species were used singly (1.08V). A consortium of the four isolates elicited a synergis effect, generating 1.57V of voltage. Stacking of the Microbial Fuel Cell(MFC) components improved voltage to 2.4V due to its lower internal resistance within the stacked materials. It is apparent from the results obtained in this study that when properly harnessed, microbial fuel cells (MFCs) technology could serve as alternate source of renewable energy.
