我们报告了一种简单,温和,合成清洁的方法,以加速酶促氧化反应的速率高达100倍时,与传统的批处理气/液系统。H2 O2的生物催化分解用于直接在反应介质中产生O2的可溶性源,从而使O2水溶液的浓度在安全和实用的条件下增加到超过平衡溶解度。为了最好地利用这种方法,开发了一种新型的流动反应器,以最大限度地提高生产率(g产品L−1h−1)。 这种可扩展的台式方法与传统的生物氧化相比具有明显的优势,因为不使用加压气体或专业设备。该方法对不同的氧化酶具有通用性,并与多种官能团相容。这些结果最终导致了生物氧化的创纪录时空产率。
We report a simple, mild, and synthetically clean approach to accelerate the rate of enzymatic oxidation reactions by a factor of up to 100 when compared to conventional batch gas/liquid systems. Biocatalytic decomposition of H2O2is used to produce a soluble source of O2directly in reaction media, thereby enabling the concentration of aqueous O2to be increased beyond equilibrium solubility under safe and practical conditions. To best exploit this method, a novel flow reactor was developed to maximize productivity (g product L−1h−1). This scalable benchtop method provides a distinct advantage over conventional bio‐oxidation in that no pressurized gas or specialist equipment is employed. The method is general across different oxidase enzymes and compatible with a variety of functional groups. These results culminate in record space‐time yields for bio‐oxidation.
