Immiscible multiphase flow in porous media is largely affected by interfacial properties, manifested in contact angle and surface tension. The gas-liquid surface tension can be significantly altered by suspended particles at the interface. Particle-laden interfaces have unique properties, for example, a lower surface tension of interfaces laden with surfactants or nanoparticles. This study investigates the impacts of a motile bacteriumEscherichia coli(E. coli, strain ATCC 9637) on the air-water surface tension. Methods of the maximum bubble pressure, thedu Noüyring, and the pendant droplet are used to measure the surface tension of the motile-bacteria-laden interfaces. Measured surface tension remains independent to theE. coliconcentration when using the maximum bubble pressure method, decreases with increasedE. coliconcentration in thedu Noüyring method, and presents time-dependent changes by the pendant drop method. The analyses show that the discrepancies may come from the different convection-diffusion processes ofE. coliin the flow among various testing methods.
