W. Krauss и цианобактерии IPPAS B-404 Anabaena sphaerica Born. et Flah., как при уровне фотосинтетически активной радиации 100 мкмоль фотонов/(м2⋅с), так и в темноте. Установлена зависимость количественного состава внутриклеточных метаболитов (водорастворимых белков и неполярных липидов) Chlorella sorokiniana и Anabaena sphaerica IPPAS B-404 от условий культивирования, а именно от уровня фотосинтетически активной радиации и температуры. Выявлено, что условия культивирования штаммов влияют на эффективность антибактериального действия данных метаболитов. Экспериментально определены значения минимальных ингибирующих концентраций неполярных веществ липидной природы и водорастворимых пептидных фракций в отношении грамположительной бактериальной культуры, выделенной из воздуха. Продемонстрирована антибактериальная активность неполярных липидов, экстрагированных из культуральной жидкости цианобактерии Anabaena sphaerica IPPAS B-404, в отношении используемых тест-культур бактерий: Bacillus subtilis B-3395, Enterobacter asburiae B-1048, Enterococcus durans B-603 в темноте, и на свету при уровне фотосинтетически активной радиации 100 мкмоль фотонов/(м2⋅с).</p></abstract><trans-abstract xml:lang="en"><p>This study investigated the antibacterial properties of the biologically active exo- and endometabolites of the microalgae Chlorella sorokiniana Shihira &amp; R.W. Krauss IPPAS C-1 and the cyanobacteria Anabaena sphaerica Born. et Flah. IPPAS B-404, under photosynthetically active radiation of 100 μmoL photons⋅(m2⋅s)–1 and in darkness. The dependence of the quantitative composition of intracellular metabolites (water-soluble proteins and non-polar lipids) of Chlorella sorokiniana and Anabaena sphaerica IPPAS B-404 on the cultivation conditions, namely the level of photosynthetically active radiation and temperature, was determined. The results revealed that the cultivation conditions influence the antibacterial efficiency of these metabolites. The values of minimum inhibitory concentrations of non-polar substances of lipid nature and water-soluble peptide fractions against Gram-positive bacterial culture isolated from air were determined experimentally. The antibacterial activity of non-polar lipids extracted from the culture fluid of the cyanobacterium Anabaena sphaerica IPPAS B-404 was demonstrated against the test bacterial cultures used: Bacillus subtilis B-3395, Enterobacter asburiae B-1048, Enterococcus durans B-603, both in darkness and under 100 μmoL photons⋅(m2⋅s)–1 of photosynthetically active radiation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микроводоросли</kwd><kwd>цианобактерии</kwd><kwd>неполярные соединения липидной природы</kwd><kwd>пептиды</kwd><kwd>антибактериальный эффект</kwd><kwd>бактерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microalgae</kwd><kwd>cyanobacteria</kwd><kwd>non-polar substances of lipid nature</kwd><kwd>peptides</kwd><kwd>antibacterial effect</kwd><kwd>bacteria</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The current research was financed by the Ministry of Education and Science of Tambov region, Russia, grant No. MU2024-02/22.</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">Dvoretsky DS, Temnov MS, Markin IV, Ustinskaya YaV, et al.
