Abstract
Fungal surface properties have been implicated as one of the main factors affecting
fungal colonization and adhesion to plant surfaces. Characterization of fungal surfaces through
hydrophobic measurements is important for understanding its function. Water contact angles are
a direct and simple approach for characterization of fungal surface hydrophobicity. The
objective of this study was to evaluate if utilization of undisturbed fungal cultures coupled with
versatile image analysis allow for more accurate contact angle measurements. Fungal cultures
were grown on agar slide media and contact angles were measured utilizing a modified
microscope and digital camera setup, with Low Bond Axisymmetric Drop Shape Analysis Model
(LB_ADSA) for contact angle determination. Fungal strains were categorized into hydrophobic,
hydrophilic and a newly defined hydroamphiphilic class containing fungi taxa with changing
hydrophobicity.
