Testing the adhesion of marine biofilm formers on bioresistant coatings is important to determine their fouling-release and antifouling properties. A dynamic attachment assay for the marine bacterium Cobetia marina (C. marina) was developed to test the adhesion on coatings and bioresistant surfaces. With well-defined culture conditions, the reproducibility of the microfluidic accumulation experiments with C. marina was verified using self-assembling monolayers as model surfaces. The assay discriminated the attachment of C. marina on four different surfaces with different wettability and protein resistances. In addition to these benchmark experiments on self-assembled monolayers, the adhesion of C. marina on polyglycerol coatings with different thicknesses was investigated. © 2020 Author(s).
