Fig. 3From: Bacterial polyextremotolerant bioemulsifiers from arid soils improve water retention capacity and humidity uptake in sandy soilEI24 (%) of hexadecane recorded under standard and stressful conditions. EI of hexadecane under different salt concentrations (ANOVA: p < 0.0001, F = 28.26, df = 27) (a), extremes of pH (ANOVA: p < 0.0001, F = 34.44, df = 20) (b) and temperature (ANOVA: p < 0.0001, F = 53.73, df = 20) (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
