    摘要: Sealants and caulks (i.e., polymeric fillers) disclosed herein are polymeric fillers that comprises a polymeric material composition and one or more lipolytic enzymes dispersed within the polymeric material composition. In preferred embodiments, the polymeric material composition is an acrylic latex sealant such as that in the form of a caulk and the one or more lipolytic enzymes comprises a lipase such as, preferably, a triacylglycerol lipase. Advantageously, the one or more lipolytic enzymes of such sealants and caulks degrades lipid-containing contaminants and resulting lipid-containing stains that contain lipids. The degradation is a result of the ability of a lipolytic enzyme to catalyze a reaction on a lipid-containing substance (i.e., a substrate) to hydrolyze or move (e.g., intra-esterification) ester bonds of such lipid-containing substance. This lipid-degradation functionality at least partially inhibits the growth of such mold and mildew resulting from exposure to lipid-containing contaminants.

    摘要: Disclosed herein are peptide-containing anti-microbial coating compositions. The peptide-containing anti-microbial coating compositions can comprise an acrylic latex coating composition, an anti-microbial enzyme dispersed within the acrylic coating composition and an anti-microbial peptide dispersed within the acrylic coating composition. The anti-microbial enzyme and the anti-microbial peptide are jointly selected to synergistically enhance lysis efficacy of the coating composition in comparison to lysis efficacy of the coating composition with the anti-microbial enzyme alone. The acrylic coating can be an acrylic latex coating composition is an acrylic latex paint.
