The catalytic activity of baker's yeast, Saccharomyces cerevisiae, as a biocatalyst was investigated in a mediatorless microbial fuel cell. The yeast cells that adhered on the anode surface were the active biocatalyst for glucose oxidation in a mediatorless biofuel cell, suggesting that the electron transfer took place through the surface confined species. The species in the anolyte solution including the dispersed yeast cells did not take a part in the electron transfer and thus in the power generation.
研究了无介体微生物燃料电池中面包酵母（Saccharomyces cerevisiae）作为生物催化剂的催化活性。附着在阳极表面的酵母细胞是无介体生物燃料电池中葡萄糖氧化的活性生物催化剂，这表明电子通过表面受限物种进行传递。阳极电解液中的物种（包括分散的酵母细胞）不参与电子转移，因此也不参与发电。
