摘要

An application of Saccharomyces cerevisiae in the two-chamber microbial fuel cells (MFCs) prototype was presented. Glucose was used as a carbon source. The influence of its concentration as well as the initial yeasts concentration on the obtained voltage was presented. Investigations were performed in the batch mode. Methylene blue at the concentration of 1 g/L was used as a mediator to enable electron transfer from the microbial cells. Easy accessible hydrogen peroxide was applied as an oxygen source. The voltage produced by the microorganisms in MFCs was monitored in real-time with Picolog 1012 from Pico Technology T. The voltage was obtained, when the substrate concentration was significantly higher than the yeasts concentration. The highest voltage of about 30-38 mV was achieved after 40 h of MFCs work for the initial glucose and yeasts concentrations 50 g/L and 30 g/L, respectively. The culture phase, in which energy was generated, was delayed in relation to the glucose uptake from the solution. As a summary of the research, the concept of an integrated process composed of membrane separation nodes and bioreactor processes was proposed.
