近年来,人们大力发展清洁能源技术以替代化石燃料,助力应对气候变化。一种方法是利用细菌和光合生物进行外部电子传输的能力,以在生物电化学电池中产生电力。在这项工作中,我们首先证明海葵 Nematostella vectensis 和卤虫卵分泌氧化还原活性分子,可以还原电子受体细胞色素 C。我们应用 2D 荧光光谱法并鉴定 NADH 或 NADPH 为分泌物种。最后,我们将可以与生物电化学细胞整合的生物体范围扩大到海葵类群,首次表明线虫和卤虫卵在整合到生物电化学细胞中时可以产生电流。
In recent years, extensive efforts have been made to develop clean energy technologies to replace fossil fuels to assist the struggle against climate change. One approach is to exploit the ability of bacteria and photosynthetic organisms to conduct external electron transport for electricity production in bio-electrochemical cells. In this work, we first show that the sea anemones Nematostella vectensis and eggs of Artemia (brine shrimp) secrete redox-active molecules that can reduce the electron acceptor Cytochrome C. We applied 2D fluorescence spectroscopy and identified NADH or NADPH as secreted species. Finally, we broaden the scope of living organisms that can be integrated with a bio-electrochemical cell to the sea anemones group, showing for the first time that Nematostella and eggs of Artemia can produce electrical current when integrated into a bio-electrochemical cell.
