[The role of Thermomyces lanuginosus strains in the biodegradation of rapeseed oil].

The aim of this study was the evaluation of the thermophilic fungus Thermomyces lanuginosus (syn. Humicola lanuginosa) in the biosynthesis of lipolytic enzymes. The investigated material contained 144 strains of this fungus isolated from biohumus, garden compost, leaf compost, mushroom compost, hazelnuts and raw coffee beans. The incubation was conducted at 55 degrees C on the solid medium with 1.5% rape oil. The study proved, that all tested strains were able to the hydrolysis of the rape oil. The highest lipolytic activity have the strains isolated from the hazelnuts. It was found the significant negative correlation between the diameters of the colonies investigated strains and their lipolytic activity.
