Abstract

The enhancement of bioelectrochemical properties of microorganism by in situ formation of conducting polymer within the cell structures (e.g. cell wall) was performed. The synthesis of polypyrrole (Ppy) within fungi (Aspergillus niger) cells was achieved. Two different Aspergillus niger strains were selected due to their ability to produce glucose oxidase, which initiated the Ppy formation through products of enzymatic reaction. The evolution of Ppy structural features was investigated by absorption spectroscopy, cyclic voltammetry and Fourier transform infrared spectroscopy.

摘要

通过在细胞结构（例如细胞壁）内原位形成导电聚合物来增强微生物的生物电化学性质。实现了聚吡咯（Ppy）在真菌（黑曲霉）细胞内的合成。选择了两种不同的黑曲霉菌株，因为它们能够产生葡萄糖氧化酶，通过酶反应的产物来引发 Ppy 的形成。通过吸收光谱、循环伏安法和傅里叶变换红外光谱研究了 Ppy 结构特征的演变。
