二羟基菲,荧蒽和pyr衍生物是相应母体多环芳烃(PAH)细菌分解代谢中的中间体。二羟基物质的开环,随后进行一系列的酶催化反应,生成代谢物,这些代谢物进入克雷布斯循环,最终产生二氧化碳和水。描绘这些途径并将其用于有用目的的一个复杂之处在于,最初的酶促加工过程会产生多种具有多种开环可能性和产物的二羟基PAH。作为解决该问题的系统努力的一部分,合成了八种二羟基物质,并将其表征为二甲氧基或二乙酸酯衍生物。在菲的菲降解途径中用两种双加氧酶检查了几种二羟基化合物。Vanbaalenii分枝杆菌PYR-1。PhdF处理了一个3,4-二羟基菲,其k cat / K m为6.0×10 6 M -1 s -1,该值与该途径中PhdF的注释功能一致。PhdI处理的k cat / K m为3.1×10 5 M -1 s -1的1-羟基-2-萘甲酸,也与该途径中的拟议作用一致。这些观察结果为vanbaaleni
The present invention relates to compositions for encapsulation of biomaterials in a silica-matrix. The present invention includes a composition for formation of a silica-matrix encapsulated biomaterial. The composition includes a reactive silicon compound and a biomaterial with a catalytic activity. When encapsulated in the silica-matrix, the biomaterial at least partially retains its catalytic activity. The present invention also relates to methods of making silica-matrix encapsulated biomaterials, and to methods of using silica-matrix encapsulated biomaterials, including methods of treating water or gas using the silica-matrix encapsulated biomaterials.
