Shewanella oneidensis MR‐1 strain with a higher cytoplasmic c‐di‐GMP level had a higher Fe(III) reduction rate and greater expression of genes that code for the proteins involved in the Mtr pathway. Single‐cell Raman microspectroscopy revealed a great increase of c‐type cytochromes in the high c‐di‐GMP strain as compared to MR‐1 wild‐type strain. c‐di‐GMP regulation system indirectly or directly positively regulates the expression of cytochromes involved in the extracellular electron transport (EET) in S. oneidensis .
