В то же время с технологической точки зрения наличие остаточного глицерина затрудняет процесс сушки биомассы, на основе которой может быть разработана кормовая добавка для сельскохозяйственных птиц и животных. Цель работы заключалась в определении количества глицерина, глюкозы и Твин-80 методом математического планирования (полный факторный эксперимент типа 23) и апробации подобранной питательной среды при глубинном культивировании Mycolicibacterium neoaurum в ферментационной установке объемом 3 л. В ходе проведенного исследования осуществлена оценка накопления биомассы Mycolicibacterium neoaurum и содержания в ней β-каротина при замене глицерина (20 г/л) на комбинацию глицерина (10 г/л) и глюкозы (10 г/л). Установлено, что при культивировании Mycolicibacterium neoaurum в среде, содержащей комбинацию глицерина и глюкозы, продуктивность штамма по биомассе и β-каротину сопоставима с контрольными условиями и составляет 17,8 г/л и 182,5 мг/кг соответственно. Исследование также показало, что внесение Твин-80 (1 г/л) в питательную среду увеличило выход биомассы и β-каротина на 14,0 и 32,2% соответственно по сравнению с контролем. Установлено, что при выращивании Mycolicibacterium neoaurum в биореакторе с использованием ростовой среды, состав которой рассчитан с использованием полного факторного эксперимента типа 2 3 , содержащей глицерин (15,0 г/л), глюкозу (5,0 г/л) и Твин-80 (1,5 г/л), продуктивность штамма по β-каротину составила 376,5 мг/кг, по биомассе – 25,2 г/л.</p></abstract><trans-abstract xml:lang="en"><p>The replacement of glucose with glycerol has demonstrated the most significant influence on beta-carotene biosynthesis using Mycolicibacterium neoaurum AC-3067D. However, from a technological standpoint, residual glycerol hinders the drying of biomass, which can be used to produce feed additives for poultry and livestock. This study aims to determine the optimal concentrations of glycerol, glucose, and Tween 80 using a 23 full factorial experiment, along with testing an optimized medium during the deep cultivation of Mycolicibacterium neoaurum in a 3L bioreactor. We evaluated the accumulation of Mycolicibacterium neoaurum biomass and beta-carotene content in response to the replacement of 20 g/L glycerol with a combination of 10 g/L glycerol and 10 g/L glucose. The results demonstrated comparable productivity of the strain between the modified and control media, yielding 17.8 g/L biomass and 182.5 mg/kg beta-carotene. The study showed that the incorporation of Tween 80 (1 g/L) into the nutrient medium resulted in a 14.0% and 32.2% increase in biomass and beta-carotene yield, respectively, in comparison to the control. The medium, optimized using a 2 3 full factorial experiment, contained glycerol (15.0 g/L), glucose (5.0 g/L), and Tween 80 (1.5 g/L). The cultivation of Mycolicibacterium neoaurum in a bioreactor using this growth medium resulted in a maximum productivity of 376.5 mg/kg of beta-carotene and 25.2 g/L of biomass.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>каротиноиды</kwd><kwd>Mycolicibacterium neoaurum</kwd><kwd>биосинтез</kwd><kwd>культивирование</kwd><kwd>биореактор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carotenoids</kwd><kwd>Mycolicibacterium neoaurum</kwd><kwd>biosynthesis</kwd><kwd>cultivation</kwd><kwd>bioreactor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (тема № 123012000071-1).</funding-statement><funding-statement xml:lang="en">The research was carried out within the state assignment of Ministry of Science and Higher Education of the Russian Federation (theme no. 123012000071-1).</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">Pagels F., Vasconcelos V., Guedes A.C.
