The sources of conductance changes during reduction of trimethylamine oxide to trimethylamine by Escherichia coli with formate as electron donor and in the presence of phosphate buffer were investigated. Theoretical considerations and experimental results suggest that the major source of conductance change is the conversion of dihydrogen phosphate to hydrogen phosphate. This transformation contributes almost twice as much to the total conductance change as does the conversion of uncharged trimethylamine oxide to charged trimethylammonium.
研究了在以甲酸盐作为电子供体且存在磷酸盐缓冲液的情况下，大肠杆菌将氧化三甲胺还原为三甲胺过程中电导变化的来源。理论分析和实验结果表明，电导变化的主要来源是磷酸二氢根向磷酸氢根的转化。这种转化对总电导变化的贡献几乎是不带电荷的氧化三甲胺向带电荷的三甲铵转化的两倍。
