Abstract

This paper presents results of toxicity testing series, in which four synthetic surfactants, two commercial oil dispersants, and six bio surfactants have been examined. The test systems were bacterial growth inhibition, microalgae growth inhibition, and microflagellate growth inhibition and biodegradation rate. The multiplication of bacteria was stimulated by surfactants, whilst that of microflagellates and microalgae was inhibited. This may be due to the metabolic usage of surfactants, especially biosurfactants by the bacteria. No toxicity could be detected with the glucose lipid GL, produced by the marine bacterium Alcaligenes sp. MMI. Most biosurfactants were degraded faster than synthetic dispersants.
