Abstract

To study bacterial behavior under varying hydration conditions similar to surface soil, we have developed a system called the Pressurized Porous Surface Model (PPSM). Thin liquid films created by imposing a matric potential of -0.4 MPa impact gene expression and colony development in Pseudomonas putida.
