Abstract: The present invention also relates to an anti-fouling composition comprising one or more aerogels. In one embodiment the aerogel encapsulate one or more bioactive agents. The one or more encapsulated bioactive agents can in one preferred embodiment be released from the aerogel over time. In one embodiment the encapsulated bioactive agents comprise one or more enzymes. In one preferred embodiment the anti-fouling composition comprising one or more aerogels is a coating composition.

Abstract: The present invention relates to self-polishing, anti-fouling coating compositions comprising an enzyme, methods for producing such coating compositions and uses thereof. The coating composition can comprise e.g. a pigment in which case the coating composition can be used as a painting composition. In a first aspect, the invention relates to a self-polishing anti-fouling coating composition comprising a first enzyme having anti-fouling activity, and at least one hydrolysable polymer composition capable of being non-enzymatically hydrolysed in an aqueous environment. In a further aspect there is provided a self-polishing anti-fouling coating composition comprising a first enzyme having anti-fouling activity, a second enzyme having polymer-hydrolysing activity, and at least one hydrolysable polymer composition capable of being hydrolysed by said second enzyme. In the latter case, the first enzyme does preferably not contribute to the self-polishing effect.

Abstract: The present invention in one aspect relates to a coating composition comprising at least one enzyme capable of acting on a compound, wherein said action results in the formation of an antifouling species comprising an antifouling activity, and wherein said compound does not form part of said coating composition. The coating composition preferably comprises at least one oxidase capable of acting on a compound, such as a substrate for said oxidase, wherein said action results in the formation of an antifouling species including an antimicrobial species comprising an antimicrobial activity. More preferred, the oxidase comprises an activity which results in the formation of a peroxide.

Abstract: An antifouling paint composition comprising an enzyme, such as endopeptidase, Subtilisin (EC 3.4.21.62) and Alcalase®, and a rosin compound, wherein the enzyme is effective to reduce or prevent fouling by aquatic organisms of a surface coated with the composition. Also disclosed is a method for preventing fouling of a surface by aquatic organisms.

Abstract: Combinations of alkaline Bacillus protease with alkaline fungal or actinomycete protease show improved detergency. Proteases obtainable from Fusarium sp. or Paecilomyces sp. (fungal) and Nocardiopsis sp. (actinomycete) are preferred.
