The paper firstly elucidates the mechanism of bacterial adhesion to oil-water interface, which is based on extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory, and then the effects of cell surface properties, oil phase and water phase on bacterial adhesion. Finally, it introduces a few applications of bacterial adhesion in Microbial Enhanced Oil Recovery (MEOR), bioemulsification, biodemulsifica
