Abstract
Deleting individual genes for outer surface c-type cytochromes in Geobacter sulfurreducens partially inhibited the reduction of humic substances and anthraquinone-2,6,-disulfonate. Complete inhibition was obtained only when five of these genes were simultaneously deleted, suggesting that diverse outer surface cytochromes can contribute to the reduction of humic substances and other extracellular quinones.
摘要
在脱硫肠状菌中删除个别细胞外 c 型细胞色素基因部分抑制了腐殖质和蒽醌-2,6,-二磺酸盐的还原。只有当同时删除这 5 个基因时才能完全抑制，这表明不同的细胞外细胞色素可以促进腐殖质和其他细胞外醌的还原。
