Показано, что замена 25, 50, 65 и 75 % NaHCO3 (4,2; 5,88; 8,4 и 12,6 г/л) на NaOH (0,05; 0,10; 0,13 и 0,15 г/л соответственно) в питательной среде не влияет на продуктивность водоросли по сравнению с контролем (стандартная питательная среда Заррука, содержащая 16,8 г/л NaHCO3 ), а количество хлорофилла а и каротиноидов (виолаксантина, лютеина и β-каротина) во всех опытных вариантах остается на уровне контроля. В то же время использование модифицированной питательной среды приводило к снижению количества фикоцианина, который не только является фотосинтетическим пигментом, но и признан одним из наиболее эффективных антиоксидантов. При замене 65 и 75 % NaHCO3 на NaOH содержание фикоцианина уменьшалось на 16 и 34 % соответственно. Использование гидроксида натрия вместо бикарбоната натрия в среде культивирования позволило существенно снизить затраты на получение биомассы спирулины. Согласно полученным результатам, показателем качества биомассы спирулины при частичной замене NaHCO3 на NaOH в питательной среде является уровень таких фотосинтетических пигментов, как хлорофилл а или каротиноиды, но не уровень фикоцианина. </p></abstract><trans-abstract xml:lang="en"><p>It has been shown that the partial substitution of NaHCO3 with NaOH in the culture medium of Spirulina platensis does not lead to a change in productivity of the algal culture. Substitution of 25 to 50 % of sodium bicarbonate with sodium hydroxide makes it possible to obtain biomass with a similar content of key pigments as compared to the control (standard Zarrouk medium) while allowing for a significant reduction in the cost of reagents for the preparation of culture medium. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>модифицированная среда Заррука</kwd><kwd>пигменты</kwd><kwd>продуктивность</kwd><kwd>Spirulina platensis</kwd></kwd-group><kwd-group xml:lang="en"><kwd>modified Zarrouk medium</kwd><kwd>pigments</kwd><kwd>productivity</kwd><kwd>Spirulina platensis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Государственной программы Республики Беларусь «Наукоемкие технологии и техника» (грант № 33, 2016–2020 гг.).</funding-statement><funding-statement xml:lang="en">This work was supported by the State Program of the Republic of Belarus “Science-intensive technologies and equipment”, grant no. 33 (2016‒2020).</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">Current knowledge on potential health benefits of Spirulina / A.
