In this study, we present the synthesis and characterization of novel bi-enzymatic, magnetic-core nanocatalyst, working as a carbohydrate dehydrogenase using oxygen as a final electron acceptor. This nanocatalyst has a particularly useful feature – the nanostructures can be magnetically precipitated and again re-suspended in the batch-type bioreactor setups. Although the specific activity of immobilized enzymes inevitably decreases after synthesis, the elimination of redox mediators from the system and possibility for enzyme layer regeneration make this approach a valuable option in industrial catalytic applications.

含有线氧化还原酶的镀金磁性纳米催化剂，可用于无介质催化氧气氧化碳水化合物的氧化

在这项研究中，我们介绍了新型双酶，磁芯纳米催化剂的合成和表征，该酶以碳水化合物作为脱氢酶，使用氧作为最终电子受体。这种纳米催化剂具有特别有用的功能-纳米结构可以被磁性沉淀，并再次重新悬浮在间歇式生物反应器中。尽管合成后固定酶的比活性不可避免地降低，但是从系统中消除氧化还原介体以及酶层再生的可能性使该方法成为工业催化应用中的一种有价值的选择。
