Abstract
Mechanisms for electron transport to Fe(III) were investigated in GS-15, a novel anaerobic microorganism which can obtain energy for growth by coupling the complete oxidation of organic acids or aromatic compounds to the reduction of Fe(III) to Fe(II). The results indicate that Fe(III) reduction proceeds through a type b cytochrome and a membrane-bound Fe(III) reductase which is distinct from the nitrate reductase.
摘要
研究了一种新型厌氧微生物 GS-15 中电子向 Fe(III)的传递机制，该微生物可以通过将有机酸或芳香族化合物的完全氧化与 Fe(III)还原为 Fe(II)耦合来获得生长所需的能量。结果表明，Fe(III)还原是通过一种 b 型细胞色素和一种膜结合的 Fe(III)还原酶进行的，与硝酸盐还原酶不同。
