Isolation and Characterization of Biosurfactant-Producing Bacteria from Amapaense Amazon Soils

Figure 4

Plots of PC1-PC2 scores (a) and HCA dendrogram (b) for the biosurfactant-producing isolates based on the surface tension (σ) and emulsification indexes (E₂₄ with and without cells) results. G1, G2, G3, G4, and G5 indicate formed groups. Fenon line is indicated by the dashed line perpendicular to the HCA similarity axis.
