В работе изучался процесс окисления 2,3,6-триметилфенола в присутствии иммобилизованной пероксидазы корня хрена. В результате такого окисления был получен полупродукт витамина Е (2,3,5-триметилгидрохинон). Иммобилизация фермента проводилась на магнитные наночастицы, на SiO и AlO. Все исследованные биокатализаторы показали стабильную работу в процессе окисления 2,3,6-триметилфенола с помощью пероксида водорода. Таким образом, синтезированные биокаталитические ферментные системы могут успешно применяться в качестве альтернативных катализаторов окисления замещенных фенолов с целью получения биологически активных соединений класса витаминов. We studied the oxidation of 2,3,6-trimethylphenol in the presence of immobilized horseradish root peroxidase. As a result of this oxidation, a semi-product of vitamin E (2,3,5-trimethylhydroquinone) was obtained. The enzyme was immobilized on magnetic nanoparticles, on SiO and AlO. All the studied biocatalysts showed stable operation during the oxidation of 2,3,6-trimethylphenol using hydrogen peroxide. Thus, the synthesized biocatalytic enzyme systems can be successfully used as alternative catalysts for the oxidation of substituted phenols in order to obtain biologically active compounds of the vitamin class.
