Fig. 2From: Bacterial polyextremotolerant bioemulsifiers from arid soils improve water retention capacity and humidity uptake in sandy soilEI24 (%) of hexane recorded under standard and stressful conditions. EI of hexane under low water activity (ANOVA: p < 0.0001, F = 95.13, df = 32) (a), extremes of pH (ANOVA: p < 0.0001, F = 38.18, df = 32) (b) and different temperatures (ANOVA: p < 0.0001, F = 86.43, df = 43) (c). Results of post hoc analyses of each condition were represented as letters: different letters correspond to statistically different EI24 (%) results (α = 0.05)Back to article page
