Установлено, что исследуемые штаммы способны синтезировать индолил-3-уксусную и гиббереллиновую кислоты, сидерофоры: B. amyloliquefaciens B-11265 в количестве 5,23 мкг/мл, 1,05 мг/мл, 46,15%; B. aryabhattai В-13192 – 3,07 мкг/мл, 0,84 мг/мл, 35,50% соответственно. Результаты исследования показали, что штаммы являются биосовместимыми и не ингибируют развитие друг друга, что позволяет включить их в состав одного консорциума. Совместное культивирование штаммов показало, что соотношение микроорганизмов в питательном субстрате оказывает значительное влияние на выход целевых веществ. При соотношении B. amyloliquefacien и B. aryabhattai 1 : 1 отмечено угнетение синтеза индолил-3-уксусной кислоты, соотношения 2 : 3 и 3 : 2 приводили к снижению продуцирования гиббереллиновой кислоты. Установлено, что оптимальным соотношением, позволяющим добиться повышения выхода целевых веществ по сравнению со средними значениями, характерными для отдельных штаммов, являлось три (B. amyloliquefacien) к одному (B. aryabhattai). В данном варианте синтез ростостимулирующих веществ консорциумом составил: индолил-3-уксусная кислота – 5,31 мкг/мл, гиббереллиновая кислота – 1,23 мг/мл, сидерофоры – 51,27%. Полученные результаты свидетельствуют о высоком потенциале сконструированного консорциума для применения в сельском хозяйстве. Однако для разработки ростостимулирующего препарата на его основе необходимо провести ряд дополнительных исследований, направленных на изучение влияния штамма на сельскохозяйственные культуры в условиях лабораторных и полевых экспериментов.</p></abstract><trans-abstract xml:lang="en"><p>Growth-stimulating properties of Bacillus amyloliquefaciens B-11265 and Bacillus aryabhattai B-13192 strains were studied, and the possibility of their co-cultivation for activity intensification was evaluated. The strains under study were found to be able to synthesize indolyl-3-acetic and gibberellic acids, siderophores: B. amyloliquefaciens B-11265 in the amount of 5.23 µg/ml, 1.05 mg/ml, 46.15%; B. aryabhattai B-13192 – 3.07 µg/ml, 0.84 mg/ml, 35.50%, respectively. The research results showed that the strains were biocompatible and did not inhibit each other's development, allowing them to be included in the same consortium. Joint cultivation of the strains showed that the ratio of microorganisms in the nutrient substrate has a significant effect on the yield of the target substances. At the ratio of B. amyloliquefacien and B. aryabhattai 1 : 1, inhibition of indolyl-3-acetic acid synthesis was observed; ratios of 2 : 3 and 3 : 2 led to a decrease in gibberellic acid production. It was found that three (B. amyloliquefacien) to one (B. aryabhattai) was the optimal ratio to increase the yield of the target substances compared to the average values characteristic of individual strains. In this variant, the synthesis of growth-stimulating substances by the consortium was: indolyl-3-acetic acid – 5.31 μg/ml, gibberellic acid – 1.23 mg/ml, siderophores – 51.27%. The results obtained indicate the high potential of the engineered consortium for agricultural applications. However, in order to develop a growth-stimulating preparation based on it, it is necessary to conduct a number of additional studies aimed at investigating the effect of the strain on agricultural crops in laboratory and field experiments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биологизация</kwd><kwd>Bacillus</kwd><kwd>ростостимулирующие свойства</kwd><kwd>фитогормоны</kwd><kwd>сидерофоры</kwd><kwd>микробный консорциум</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biologization</kwd><kwd>Bacillus</kwd><kwd>growth-stimulating properties</kwd><kwd>phytohormones</kwd><kwd>siderophores</kwd><kwd>microbial consortium</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания по теме «Исследование потенциала ростостимулирующих бактерий для повышения агрономической биофортификации пшеницы» (шифр FZSR-2024-0009).</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the state task on the topic “Research of the potential of growth-stimulating bacteria to increase the agronomic biofortification of wheat” (code FZSR-2024-0009).</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">Kumawat K.C., Razdan N., Saharan K.
