  Disclosed herein are polymeric materials such as a coating, a plastic, a laminate, a composite, an elastomer, an adhesive, or a sealant; a surface treatment such as a textile finish or a wax; a filler for such a polymeric material or a surface treatment that includes an enzyme such as an esterase (e.g., a lipolytic enzyme, a sulfuric ester hydrolase, an organophosphorus compound degradation enzyme), an enzyme (e.g., a lysozyme, a lytic transglycosylase) that degrades a cell wall and/or a cell membrane component, a biocidal or biostatic peotide, and/or a peptidase. Also disclosed herein are methods of altering a material's property such as service life, flexability, or rigidity, by incorporation of an enzyme into a material capable of being chemically crosslinked by the activity of a lipolytic enzyme, a hydrolase, and/or a urease.

  本文公开了一些聚合材料，如涂层、塑料、层压板、复合材料、弹性体、粘合剂或密封剂；一种表面处理，如纺织品涂层或蜡；一种填料，用于这样的聚合材料或表面处理，其中包括一种酶，如酯酶（例如，脂肪水解酶，硫酸酯水解酶，有机磷化合物降解酶），降解细胞壁和/或细胞膜成分的酶（例如，溶菌酶，裂解转糖基酶），生物杀菌或生物静态肽，以及/或肽酶。本文还公开了通过将酶纳入可通过脂肪水解酶、水解酶和/或脲酶的活性交联材料中来改变材料性能，如使用寿命、柔韧性或刚度的方法。
