Полученные наночастицы были исследованы методом ИК-спектроскопии диффузного отражения и вводились в ЖФБ на этапе его дозревания в объемном соотношении ЖФБ:раствор частиц 50:1. В результате получено два новых биопрепарата ЖФБ-Fe и ЖФБ-Cu. Все биопрепараты, а также наночастицы железа (Fe НЧ) и меди (Cu НЧ) были протестированы в лабораторном эксперименте на семенах льна сорта Тверской. Наночастицы железа или меди в составе биопрепаратов положительно повлияли на всхожесть семян. В варианте ЖФБ-Fe всхожесть семян составила 86–91%, что на 3–12% больше по сравнению с контролем. В случае использования ЖФБ-Cu всхожесть семян варьировалась от 86 до 93%, что на 3–11% больше по сравнению с контролем. Однако максимальная средняя длина одного проростка в этих вариантах составила 14,5–14,8 см. Тогда как на среднюю длину одного проростка существенно повлиял полив семян раствором, содержащим только наночастицы железа, т.к. в данном варианте было отмечено максимальное значение данного параметра (16,1±1,2 см). Полученные результаты показали, что данное исследование весьма перспективно, но требует дополнительных экспериментов по варьированию концентрации наночастиц в биопрепарате ЖФБ.</p></abstract><trans-abstract xml:lang="en"><p>This work sets out to investigate a green-synthesized biopreparation produced by introducing iron or copper nanoparticles into a microbial liquid-phase biological product (LBP). The obtained nanoparticles were analyzed by diffuse reflectance IR spectroscopy and introduced into the LPB at the stage of its ripening in the LPB:particle solution volume ratio of 50:1. As a result, two new biopreparations – LPB-Fe and LPB-Cu – were obtained. All LPB samples, as well as iron and copper nanoparticles, underwent laboratory testing on flax seeds of Tverskaya variety. Iron or copper nanoparticles in the composition of biological preparations were found to affect positively the process of seed germination. In the LPB-Fe variant, seed germination ranged between 86–91%, which exceeded that in the control by 3–12%. In the LPB-Cu variant, seed germination ranged between 86–93%, which exceeded that in the control by 3–11%. However, in the latter variant, the maximum average length per seedling was 14.5–14.8 cm. The average length per seedling was significantly affected by watering the seeds with a solution containing only iron nanoparticles, with the maximum value of this parameter reaching 16.1±1.2 cm. According to the results obtained, this research direction has good prospects and requires additional experiments by varying the nanoparticle concentration in LBPs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы железа</kwd><kwd>наночастицы меди</kwd><kwd>биопрепарат ЖФБ</kwd><kwd>всхожесть семян</kwd><kwd>лен-долгунец</kwd><kwd>биометрические параметры Финансирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>iron nanoparticles</kwd><kwd>copper nanoparticles</kwd><kwd>biopreparation LPB</kwd><kwd>seed germination</kwd><kwd>long-stalked flax</kwd><kwd>biometric parameters</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РНФ № 22-76-00016.</funding-statement><funding-statement xml:lang="en">The work was financially supported by the Russian Scientific Foundation (project no. 22-76-00016)</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">Bhagat M., Anand R., Sharma P., Rajput P., Sharma N., Singh K.
