Данные соединения обладают разнообразными эффектами, включая антиоксидантный, противовоспалительный, антибактериальный и анти-QS. Таким образом, фитобиотики могут представлять потенциальный инструмент для лечения и профилактики инфекционных заболеваний сельскохозяйственных животных. Однако значимым побочным эффектом у некоторых из них является гепатотоксичность, поэтому для безопасного использования данных соединений в качестве кормовых добавок необходимы более детальные исследования, включая дозу, биодоступность, метаболические взаимодействия и риски, связанные с длительным воздействием. Целью данного исследования стала оценка токсичности кормовых добавок на основе фитобиотиков 7,8-дигидрокси-4-метилкумарина и ванилиновой кислоты с использованием рекомбинантного люминесцирующего штамма Escherichia coli K12 MG1655 pXen7 и представителя реснитчатых простейших Stylonychia mytilus, являющегося стандартным тест-объектом для определения общей токсичности кормов. Оценка токсичности изучаемых соединений с использованием двух тест-объектов показала различия в их активности. В ходе исследований была зафиксирована абсолютная токсичность ванилиновой кислоты. Для бактериального биосенсора наблюдалось полное подавление свечения при максимальных концентрациях (0,0125 и 0,125 М), а для стилонихий – мгновенный лизис клеток во всем диапазоне концентраций уже через 1 ч экспозиции. На этом фоне меньший токсический эффект был характерен для 7,8-дигидрокси-4 -метилкумарина, у которого токсический эффект проявлялся при высоких дозах и исчезал с уменьшением концентрации тестируемого соединения. Однако для Stylonychia mytilus через 3 ч экспозиции было зафиксировано токсическое действие во всех оставшихся экспериментальных точках. Результаты исследования указывают на необходимость строгого контроля использования фитобиотиков в кормлении сельскохозяйственных животных и подчеркивают важность более глубокого изучения данных кормовых добавок.</p></abstract><trans-abstract xml:lang="en"><p>Phytobiotic feed additives have promising potential in the feeding of farm animals, providing improved health and productivity. These compounds have a variety of effects, including antioxidant, anti-inflammatory, antibacterial, and anti-QS. Thus, phytobiotics may represent a potential tool for the treatment and prevention of infectious diseases of farm animals. However, hepatotoxicity is a significant side effect of some of them, so more detailed studies are needed to safely use these compounds as feed additives, including dose, bioavailability, metabolic interactions, and risks associated with long-term exposure. The purpose of this research was to evaluate the toxicity of two phytobiotic compounds, 7,8-dihydroxy-4-methylcoumarin and vanillic acid, using a recombinant luminescent strain of Escherichia coli K12 MG1655 pXen7 and a representative ciliated protozoon, Stylonychia mytilus. These two test organisms are commonly used to assess the overall toxicity of feeds. The results of the study showed differences in the toxicity levels of the two compounds when tested using both organisms. Vanillic acid exhibited higher toxicity than 7,8-dihydroxy-4-methylcoumarin. For the bacterial biosensor, complete suppression of luminescence was observed at maximum concentrations (0,0125 and 0,125 M). For Stylonychia, instant cell lysis was observed across the entire concentration range after one hour of exposure. In contrast, 7,8-dihydroxy-4-methylcoumarin showed a lower toxic effect, with the toxic effect only manifesting itself at high doses and disappearing with a decrease in concentration. However, after three hours of exposure for Stylonychia mytilus, a toxic effect was still recorded at all remaining experimental sites. These results emphasize the need for careful monitoring of phytobiotic use in animal feed and highlight the importance of further research on these feed additives.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бактериальная люминесценция</kwd><kwd>токсичность</kwd><kwd>7</kwd><kwd>8-дигидрокси -4-метилкумарин</kwd><kwd>ванилиновая кислота</kwd><kwd>Escherichia coli</kwd><kwd>Stylonychia mytilus</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bacterial luminescence</kwd><kwd>toxicity</kwd><kwd>7</kwd><kwd>8-dihydroxy-4-methylcoumarin</kwd><kwd>vanillic acid</kwd><kwd>Escherichia coli</kwd><kwd>Stylonychia mytilus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 25-26-00251, https://rscf.ru/project/25-26-00251/</funding-statement><funding-statement xml:lang="en">The research was carried out within the framework of the Russian Science Foundation grant number 25-26- 00251,https://rscf.ru/project/25-26-00251/</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рязанов В.А.
