“…Indeed, besides the surface area, the architecture, texture, and roughness of the surface of the support material can play a significant role on the colonization and charge transfer process in MFC [28,61], as well as in the microbial colonization in other microbial processes of pollution control [62,63]. For instance, Kano et al [61] observed that the micro scale surface topography of anodes strongly affected the performance of MFC.…”
