DC3000 growth and survival in K broth containing NaCl to confer various water potentials. Cell density was measured by viable plate count (A) and optical density at 600 nm (B). The water potentials examined were 0 (•), -0.2 (○), -0.5 (▪), -0.9 (□), -1.4 (▴), -1.8 (▵), -2.3 (♦2), -2.7 (⋄), -3.7 (▾), and -4.6 (▿) MPa. These results are representative of two independent experiments. Values represent the mean ± SE (n = 3).
