Fig. 2: Metabolic versatility of Shewanella spp.
From: Insights into the various mechanisms by which Shewanella spp. induce and inhibit steel corrosion
(top) Illustration of all the metabolic traits of Shewanellae relevant for microbial corrosion. (Bottom) Presence of genes encoding the indicated enzymes across reference genomes from the eight species of Shewanella linked to microbial corrosion, as well as overall prevalence across 97 named Shewanella species. Note that CymA has a central function in electron transfer to many different terminal electron acceptors, and that Otr has been shown to reduce nitrite, tetrathionate, and hydroxylamine. Details on the methods and additional information is available in Supplementary Information. The genome comparison shows that most of the metabolic traits relevant for microbial corrosion are common among Shewanella spp., including those which are not yet linked to microbial corrosion.
