“…Therefore, lower performance was obtained in MFC 1 (inoculated with L. starkeyi ) compared to other MFCs, possibly due to the inefficient electron transfer between yeast and electrode. Previous studies showed that yeast cells (i.e Hansenula anomala , Saccharomyces cerevisiae , and Candida melibiosica ) produced lower electrical power without the addition of electron transfer mediators in MFC . This is because the wall of a yeast cell is usually composed of thick (100–200 nm) polysaccharides and proteins.…”

“…Previous studies showed that yeast cells (i.e Hansenula anomala, Saccharomyces cerevisiae, and Candida melibiosica) produced lower electrical power without the addition of electron transfer mediators in MFC. 42 This is because the wall of a yeast cell is usually composed of thick (100−200 nm) polysaccharides and proteins. Moreover, the cytochromes of the yeast are found in the mitochondrial region and the trans-plasma membrane electron transport systems are found in the cell membrane, which are surrounded by the cell wall.…”

“…Therefore, to get an electrochemical response from yeast, it is believed that the mediator compounds should pass through the cell wall and interact with the components of the membrane and/or internal redox centers or that the response comes from soluble electroactive compounds released from the cell. 43 Lee et al 42 reported that the redox compounds, changing between an oxidized state (Med ox ) and a reduced state (Med red ) are necessary for the yeast to reach the electron transport chain (ETC) located in the mitochondria of the cell.…”

Although exogenous mediators can distinctly enhance the performance of yeast driven microbial fuel cell (MFC), the possibility of mediator's toxicity, environmental risk, and cost are the main challenges facing toward its application in MFCs. Therefore, the use of naturally produced electron shuttles for unmediated yeast would be of great interest since it can solve most of the above-mentioned problems. The present study is to investigate the possibility of the use of electron shuttle producing bacteria Klebsiella pneumonia (K. pneumonia) to boost up the performance of yeast Lipomyces starkeyi (L. starkeyi) driven MFC. The MFCs inoculated with L. starkeyi and K. pneumoniae coculture achieved a maximum power density of 12.87 W/m 3 which is about 3 and 6 times higher than that of MFC solely inoculated with pure yeast and bacteria, respectively, demonstrating that the yeast cells have successfully utilized the reduced electron shuttles excreted by the bacteria. The occurrence of the mutualistic interactions was further supported by the CV and EIS results. The findings of this work suggest that the use of mutualistic interaction of yeast and bacteria could be a new way to increase the performance of the MFCs.

Fungi are among the microorganisms able to generate electricity as a result of their metabolic processes. Throughout the last several years, a large number of papers on various microorganisms for current production in microbial fuel cells (MFCs) have been published; however, fungi still lack sufficient evaluation in this regard. In this review, we focus on fungi, paying special attention to their potential applicability to MFCs. Fungi used as anodic or cathodic catalysts, in different reactor configurations, with or without the addition of an exogenous mediator, are described. Contrary to bacteria, in which the mechanism of electron transfer is pretty well known, the mechanism of electron transfer in fungi-based MFCs has not been studied intensively. Thus, here we describe the main findings, which can be used as the starting point for future investigations. We show that fungi have the potential to act as electrogens or cathode catalysts, but MFCs based on bacteria–fungus interactions are especially interesting. The review presents the current state-of-the-art in the field of MFC systems exploiting fungi.

“… 23 Additionally, yeast cell membrane contains higher protein which is useful as the electrochemically active sites to capture electrons via EET to generate power. 24,25 Several studies have reported the effectiveness of using various yeasts as biocatalysts in MFC systems, such as Saccharomyces cerevisiae sp., 21 Candida sp., 26 and Arxula adeninivorans . 27 …”
