Biocorrosion on Nanofilms Induces Rapid Bacterial Motions via Iron Dissolution

Abstract: Stability and reactivity of solid metal or mineral surfaces in contact with bacteria are critical properties for development of biocorrosion protection and for understanding bacteria−solid environmental interactions. Here, we opted to work with nanosheets of iron nanolayers offering arbitrarily large and stable areas of contact that can be simply monitored by optical means. We focused our study on the sediments' bacteria, the strain Shewanella oneidensis WT MR-1, that served as models for previous research on … Show more

“…Titanium is used to facilitate iron adhesion as commonly reported in the literature 33 but it also constitutes an additional conductive layer that can assist the redox reactions. Note however that we did not notice any bias in our previous study performed on nanofilms 30 . Figure 3 A shows the typical sequence of images (bottom views) that were recorded over periods that could extend to about one week; Movie S2 corresponds to the complete time-lapse sequence of pictures.…”

“…As reported in a previous work 30 , the optical semi-transparency of nanofilms allowed us to simply monitor the corrosion process by optical means (see Material and Methods). Figure 1 presents time evolution snapshots of the corrosion and wetting processes, with side and bottom views in Fig.…”
