Abstract

Bacteria of the genus Shewanella have been studied for their versatile electron-accepting abilities, particularly for extracellular electron transfer via minerals. Shewanella marisflavi ECSMB14101 was isolated from naturally formed biofilms in the East China Sea. The genome of S. marisflavi ECSMB14101 encodes 3891 genes with a total size of 4,343,492 bp in one chromosome. Its GC content is 49.89%. S. marisflavi ECSMB14101 is able to synthesize a red pigment, which may be achieved through Cytochrome c3 and electron transfer to reduce Fe(III) oxide. The genomic data presented here could provide fundamental insights to better understand the physiological characteristics of S. marisflavi, the ecological significance of red pigment synthesis, and its inductive effects on the settlement of marine invertebrate larvae.
