Исследовать  влияние  поверхностной  освещённости  на  скорость  роста  и  соотношение пигментов интенсивной культуры Dunaliella salina; провести апробацию выращивания D. salina  для получения её  биомассы,  обогащённой β‐каротином, в полупромышленных условиях.</p></sec><sec><title>Методы</title><p>Методы. Культивирование D. salina в полупромышленных условиях проводили в тепличном модуле ФГБУН «Институт морских биологических исследований». Культиваторами служили квадратные бассейны (1×1 м), выстеленные полиэтиленовой пленкой,  уложенные на выровненную поверхность  грунта; высота  слоя  культуры  составляла 10 см, объём – 100 л; разбавление предварительно выращенной D. salina проводили  свежей  средой  без  солей  –  источников  азота  и  фосфора.  Дуналиеллу  выращивали  при  естественном  освещении  и  непрерывном перемешивании.</p></sec><sec><title>Результаты</title><p>Результаты. Определен  диапазон  поверхностной  освещённости  для  интенсивного  выращивания  D. salina,  оптимальный по энергетическим и минеральным затратам. В данном диапазоне средняя скорость роста культуры для условий эксперимента составляла 0.23‐0.27  г СВ/(л∙сут), а соотношение Кар/Хл а повышалось в 1.5‐2 раза, что свидетельствует о перестройке пигментного аппарата D. salina. Показано, что на втором этапе выращивания дуналиеллы содержание каротиноидов в бассейнах увеличилось в 1.3 раза и составило 600 мг на 1 м2 при соотношении  Кар/Хл а  равном  4.5.</p></sec><sec><title>Заключение</title><p>Заключение.  Накопление  каротиноидов  при  полупромышленном выращивании D. salina произошло под действием двух факторов: повышенной естественной освещённости и температуры без дополнительного повышения солёности и продувки углекислоты, что снижает затраты при её промышленном выращивании; данный способ может быть использован для разработки технологии получения биомассы  дуналиеллы, обогащенной β‐каротином в южных регионах Российской Федерации. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. In this work, we set out to study the effect of surface irradiance on the growth rate and the pigment ratio of D. salina, as well as to test a technology for semi‐industrial cultiva‐ tion of D. salina aimed at obtaining its biomass enriched with β‐carotene.</p></sec><sec><title>Methods</title><p>Methods. D. salina was cultivated under semi‐industrial conditions in a greenhouse module of the A. O. Kovalevsky Institute of Marine Biological Research. Square tanks (1 × 1 m) lined with polyethylene film and laid on a flat ground surface were used as propagators. The culture layer had a thickness of 10 cm and a volume of 100 litres. Pre‐grown D. salina was diluted using fresh medium without salts – sources of nitrogen and phosphorus. Dunaliella was cultivated under natural light with continuous stirring.</p></sec><sec><title>Results</title><p>Results. We determined the range of surface irradiance, which can be considered optimal for intensive cultivation of D. salina in terms of energy and mineral costs. Across this range, the average growth rate of the culture under experimental conditions amounted to 0.23–0.27 g DW/(l∙day), whereas the ratio of Car / Chl a increased by a factor of 1.5‐ 2, which indicates changes in the pigment composition of D. salina. It is experimentally shown that the content of carotenoids in the tanks increased by 1.3 times amounting to 600 mg per 1 m2 at a Car/Chl a ratio of 4.5 at the second stage of D. salina cultivation.</p></sec><sec><title>Conclusions</title><p>Conclusions. Carotenoid accumulation during semi‐industrial cultivation of D. salina occures due to two factors: in‐ creased natural irradiance and temperature without an additional increase in salinity and blowing of carbon dioxide, which reduces the costs of its industrial cultivation. This two‐stage cultivation method can be used to develop a technology for obtaining Dunaliella biomass enriched with β‐carotene in the southern regions of the Russian Federation.   </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полупромышленное  культивирование D. salina</kwd><kwd>продуктивность</kwd><kwd>соотношение каротиноиды/хлорофилл а</kwd><kwd>тепличный модуль</kwd><kwd>β‐каротин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>semi‐industrial cultivation of D. salina</kwd><kwd>productivity</kwd><kwd>Car/Chl a ratio</kwd><kwd>greenhouse module</kwd><kwd>β‐carotene</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования выполнены в рамках Госзадания ФГБУН ИМБИ РАН № 0828‐2018‐0004 и гранта РФФИ №18‐44‐920009.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The studies were conducted under the State Project of IMBR RAS No. 0828‐ 2018‐0004 and the grant No.18‐44‐920009 from the Russian Foundation for Basic Research.</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">Ben‐Amotz A., Polle J.E., Rao D.S.
