Interfacial Interactions in Microbial Bioadhesion

摘要

The objective of this research was to characterize the influenced of bacterial cell surface characteristics (exopolymers,, surface charges) on adhesion to substrata. Mutants of Pseudomonas aeruginosa with know surface characteristics were used in adhesion tests under laminar flow in aqueous environments. Spectroscopy, microscopy, and fluorescence techniques were used to quantify the relative adhesion propensity of the various mutants. It was discovered that exopolymer is not required in large amounts for adhesion however lipopolysaccharide chemistry seems to play a role in adherence and biofilm accumulation.
