Активность полученных биокатализаторов изучалась в каталитическом процессе окисления 2,3,6-триметилфенола до 2,3,5-триметилгидрохинона, который является полупродуктом синтеза витамина Е. В работе показаны преимущества использования магнитных наночастиц Fe3O4 для иммобилизации пероксидазы в каталитическом синтезе 2,3,5-триметилгидрохинона. Подобраны оптимальные условия проведения процесса окисления 2,3,6-триметилфенола: рН 7,2, температура 50 °С. Методика синтеза магнитных наночастиц Fe3O4 с использованием недорогих исходных материалов и исследованный в работе способ каталитического окисления ТМФ до ТМГХ (полупродукта синтеза витамина Е) могут быть рекомендованы как альтернатива классическому промышленному способу получения ТМГХ.</p></abstract><trans-abstract xml:lang="en"><p>We have studied the activity of biocatalysts based on peroxidase immobilizedon Al2O3, SiO2, and on magnetic nanoparticles Fe3O4, the use ofwhich is a promising direction in biotechnology. Activity of these biocatalystswas studied in the catalytic oxidation of 2,3,6-trimethylphenol(TMP) to 2,3,5-trimethylhydroquinone (TMHQ), which is an intermediatein the synthesis of vitamin E. The paper shows the advantages of magneticnanoparticles in the immobilization of peroxidase for the catalyticsynthesis of TMHQ. The optimal conditions for the reaction were foundto be pH = 7,2 and temperature of 50 °C. The methods for the synthesisof magnetic nanoparticles Fe3O4 from inexpensive raw materials and forthe catalytic oxidation of TMP can be recommended as an alternative tothe standard industrial method for producing TMHQ.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пероксидаза</kwd><kwd>иммобилизация</kwd><kwd>магнитные наночастицы</kwd><kwd>2</kwd><kwd>3</kwd><kwd>6-триметилфенол</kwd><kwd>окисление</kwd><kwd>2</kwd><kwd>3</kwd><kwd>5-триметилгидрохинон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>peroxidase</kwd><kwd>immobilization</kwd><kwd>magnetic nanoparticles</kwd><kwd>oxidation</kwd><kwd>2</kwd><kwd>3</kwd><kwd>6-trimethylphenol</kwd><kwd>2</kwd><kwd>3</kwd><kwd>5-trimethylhydroquinone</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pramparo L., Stuber F, Font J, Fortuny A., Fabregat A., Bengoa C. // J.
