Viability of P. putida mt-2 cells exposed to matric stress. The viability, following incubation without matric stress (control, Ctrl), under mild matric stress (−0.5 MPa), or under extensive matric stress (−1.5 MPa), was determined by live/dead staining and flow cytometry. Data are mean values and error bars represent the standard deviation of three biological replicate samples
