TITLE
Stability of aqueous biofilms of the Class II hydrophobin Cerato-ulmin in the presence of gaseous and liquid hydrocarbons: a phenomenological investigation
Abstract
Cerato-ulmin (CU) is a member of the hydrophobin family of fungal proteins. CU is produced by the
filamentous fungus Ophiostoma ulmi and has been implicated in Dutch elm disease. All hydrophobins feature a
particular repeat of 8 cysteine groups and exhibit high surface activity, but CU is known to produce an especially wide
variety of unusual structures in water. In this work, CU’s ability to stabilize gas bubbles and oil drops under different
conditions was assessed. Applied vacuum, acoustic energy, heat, and solvent variations were used to manipulate the
CU-stabilized structures while observing the remarkably stable structures with a combination of bright-field,
epifluorescence and confocal microscopes equipped with high-speed video cameras. Static and dynamic light
scattering reveals the presence of remarkably stable sub-micron structures in solution. Supported by the Gulf of
