  The present invention relates to a reusable print medium comprising a substrate and a sacrificial layer. The sacrificial layer contains a hotmelt composition at least comprising an amorphous material. The amorphous material is a resin being a reaction product of a first monomer A, said first monomer A being a polyhydroxyl alcohol comprising X hydroxyl functional groups, wherein X≧2, monomer A optionally comprises a primary or secondary amine functionality; a second monomer B, being an aromatic monocarboxylic acid; a third monomer C, said third monomer C being able to form an ester linkage with an alcohol and/or an amide linkage with a primary or secondary amine; and optionally, a fourth monomer D, being an aromatic monocarboxylic acid different from the second monomer B. The sacrificial layer including the printed image may be removed from the substrate by applying heat. A new sacrificial layer may be applied such that the reusable print medium is ready to be reused. The present invention also relates to a method of manufacturing a reusable print medium according to the present invention, a method of printing and recycling such a print medium and an apparatus for printing and recycling such a print medium.

  The present invention provides methods of producing dicarboxylic acids. The methods involve incubating a fatty acid or hydrocarbon substrate with an enzyme to produce a dicarboxylic acid product. The enzyme acts on the substrate to produce a product that has been both over-oxidized and has undergone cleavage of a C—C bond. In some embodiments the enzymes having these useful characteristics are mutants of a cytochrome P450 enzyme, for example an enzyme of the class CYP102 or a mutant thereof. The invention provides enzymes where these desirable characteristics can be found in a single enzyme, and thus in some embodiments the methods can be performed through the action of a single enzyme.

  本发明提供了生产二羧酸的方法。该方法涉及将脂肪酸或烃基底物与酶孵育以生产二羧酸产物。酶作用于底物以产生经过过氧化和C-C键断裂的产物。在某些实施例中，具有这些有用特性的酶是细胞色素P450酶的突变体，例如CYP102类酶或其突变体。本发明提供了这些理想特性可以在单个酶中找到的酶，因此在某些实施例中，可以通过单个酶的作用来执行该方法。
