Enzymatic Approach to Waste Minimization: Tyrosinase Reaction Chitosan Adsorption

9315449 Payne本项目旨在研究一种非资本密集型酶法，用于选择性和有效地去除中间化学工艺流程中的酚类污染物。该方法包括两个步骤，首先通过酪氨酸酶将苯酚转化为醌。然后醌通过强共价相互作用被吸附到壳聚糖吸附剂上。这种方法的优势是由于酪氨酸酶对苯酚的底物特异性，以及醌-壳聚糖吸附的强度。这一过程被认为很容易适应现有的特种化学品和商品化学品的生产操作。＊＊＊

9315449 Payne This project is to examine a non-capital-intensive enzymatic approach for selectively and efficiently removing phenolic contaminants from intermediate chemical process streams. The approach involves two steps in which phenol is first converted to its quinone by the enzyme tyrosinase. The quinone is then adsorbed to a chitosin adsorbent through strong covalent interactions. The advantage of this approach is due to the substrate specificity of tyrosinase for phenol, and the strength of the quinone-chitosin adsorption. This process is thought to be readily adaptable to existing manufacturing operations for specialty and commodity chemicals. ***
