A process for enhancing biodegradability of polyolefinic materials is provided. The process includes providing a polyolefinic material, mixing the polyolefinic material with at least one fatty reagent, heating up the polyolefinic material mixed with the at least one fatty reagent to the melting temperature of the polyolefinic material to obtain a melted material, letting the melted material cool at room temperature for a time sufficient to obtain a solidified product, and incubating the solidified product with at least one fungal mycelium selected from fungal strains secreting Unspecific Peroxygenases (UPO), in presence of a fungal culture medium.

The invention relates to polypeptides having peroxygenase activity and compositions comprising such polypeptides. The invention also relates to improved methods of producing such polypeptides in yeasts.

A liquid detergent composition, preferably a liquid manual dishwashing detergent composition, comprising one or more hydroperoxy fatty acid producing enzymes selected from the group consisting of: arachidonate lipoxygenases, alpha-dioxygenases, and mixtures thereof, preferably alpha-dioxygenases, a surfactant system and a liquid carrier (i.e., water). Methods of washing comprising the liquid detergent composition are also provided.

A detergent composition, preferably a manual dishwashing detergent composition, including one or more diol synthases capable of converting one or more unsaturated fatty acids into one or more oxylipins, and a surfactant system including one or more anionic surfactants and one or more co-surfactants selected from the group consisting of amphoteric surfactant, zwitterionic surfactant, and mixtures thereof. Method of using the detergent composition including a surfactant system and the diol synthases are also provided.

The invention relates to an unspecific peroxygenase of the Agrocybe aegerita fungus, obtained by means of directed molecular evolution to facilitate the functional expression thereof in an active, soluble and stable form. The peroxygenase described in the invention shows a significant improvement in the functional expression thereof, improved monooxygenase activity and reduced peroxidase activity, in relation to the monooxygenase and peroxidase activities showed by the unspecific wild-type peroxygenase of A. aegerita. The peroxygenase of the invention is useful in chemical processes, including industrial transformations such as the selective oxyfunctionalisation of carbon-hydrogen bonds of various organic compounds.
