SURFACE PROPERTIES OF GALVANIZED METALS AND ATTACHMENTBY THE BACTERIUM JANTHINOBACTERIUM LIVIDUM

摘要

Atomic Force Microscopy (AFM) is a useful tool for characterizing material surface propertiesrnand studying in situ bacterial biofilms formed on metal surfaces. The aims of the present study were tornevaluate metal surface roughness after a series of treatments and attachment of the bacteriumrnJanthinobacterium lividum, isolated from a drinking-water catridge, and to establish the relationshiprnbetween surface treatment and susceptibility to biofilm formation. The four metal coupons usedrnincluded Al Galvanized 0.3%, 5%, 55% and a pure zinc plate.
