Technological properties of yeast produced surface active compounds in connection with their application in clean-up technologies

Original language description

Biologically produced surfactants (SACs) can mobilize and solubilize non-aqueous phase liquids (NAPL) adsorbed onto soil constituents. The interest in microbial surfactants has increased during recent years due to their lower toxicity, higher biodegradability, selectivity and specific activity under extreme conditions than synthetic SACs. Main output of the project represents preparation of this yeast biosurfactant intended for washing of matrices contaminated by NAPL. The influence of cultivation mediacomposition on biosurfactant production was studied and basic properties (critical micelle concentration (CMC), minimum surface tension) of isolated biosurfactants were compared with properties of synthetic surfactant with surface tension measurement. The interfacial tension of the systems containing aqueous solutions of different concentrations and non-polar substances was measured with petroleum compounds (kerosene Jet A-1), aromatic and aliphatic hydrocarbons (represented by toluene
