Visualisation of Bacterial Behaviour Using Tapping-Mode Atomic Force Microscopy

Abstract:

Article Preview

Ex-situ and in-situ Tapping Mode AFM were used to investigate responses of attached bacteria to stressful conditions. For ex-situ measurements, the AFM was equipped with a customised re-positioning stage and sample mount to permit re-examination of the same surface area. For in-situ measurements, the inoculated pyrite coupon was immersed in solution in a flow through cell. Initial experiments using Sulfobacillus thermosulfidooxidans indicated that increased acidity promoted EPS production but increased salinity resulted in cell detachment.
