A robust biocatalyst was produced by immobilization of alpha-amylase into mesoporous silica thin films with local order pore structure and 11 nm pore diameter, supported on glass stripes. The activity of this novel catalyst was evaluated for direct starch degradation. The catalyst films show excellent activity, and enhanced stability with respect to free enzyme at extreme conditions of pH and temperature. In addition, they can be easily separated from the reaction media and reused several times.
通过将α-淀粉酶固定在具有局部有序孔结构和 11nm 孔径的介孔硅薄膜上，在玻璃条上制备了一种稳健的生物催化剂。该新型催化剂的活性用于直接淀粉降解。与游离酶相比，该催化剂在极端 pH 值和温度条件下表现出优异的活性和增强的稳定性。此外，它们可以很容易地从反应介质中分离出来并重复使用几次。
