Abstract: A method for the recombinant production of cannabigerolic acid in a host organism may use a modified prenyltransferase. A modified prenyltransferase, a nucleic acid molecule that codes for the modified prenyltransferase, and a recombinant organism that includes the modified prenyltransferase and/or the nucleic acid are also disclosed here.

Abstract: The invention relates to a process and an evaporator for coating a substrate by means of an arc in a vacuum chamber (10) in the case of low-pressure arc evaporation, wherein the vacuum chamber (10) has at least one evaporator, which comprises a target material (20), reactive gas supply lines (53, 54) for supplying reactive gas, and a vacuum pump, wherein the evaporator comprising the target material (20) serves as the cathode and the inner wall (36) of the vacuum chamber (10) serves as the anode between which the arc is generated. According to the invention, high-melting point metal is used as the target material (20) for catalysis, and the pressure in the vacuum chamber (20) during coating is at least 0.5 Pa, in particular at least 3 Pa, preferably 5 Pa. A layer of catalytically active metal having a high oxygen content is formed on the substrate.

Abstract: The invention relates to a method for coating one or more sides of substrates with catalytically active material, comprising material deposition under vacuum in a vacuum chamber, wherein the following steps are performed: (a) loading the vacuum chamber with at least one substrate, (b) closing and evacuating the vacuum chamber, (c) cleaning the substrate by introducing a gaseous reducing agent into the vacuum chamber, (d) increasing the size of the substrate surface by depositing a vaporous component on the substrate surface, (e) coating by a coating process taken from the group of plasma coating processes, physical gas deposition, sputtering processes or the like, wherein one or more metals and/or alkaline and/or earth alkaline metals or their oxides are applied to the surface of the substrate. This method may be used, for example, for coating electrodes which are used in the chlor-alkali electrolysis.
