Идентификация штаммов проводилась с использованием методов MALDI-TOF MS и API 50CHL. Все тестируемые штаммы проявили способность к росту в молоке. Через 24 часа инкубации они образовывали однородную плотную консистенцию, напоминающую йогурт, и обладали приятным ароматом, характерным для кисломолочных продуктов.Следует отметить, что по технологическим показателям штаммы Lactobacillus acidophilus 3.7 и Lactobacillus acidophilus 3.10 продемонстрировали наилучшие результаты: общее количество клеток составило соответственно 3,6 ± 2,3×10⁸ и 1,8 ± 4,0×10⁹ КОЕ/мл, а значения pH – 3,6 и 3,7. Установлено, что из девяти исследуемых культур восемь штаммов проявили положительную экзополисахаридпродуцирующую активность. Эти штаммы были отобраны для последующей оценки пробиотических свойств для применения их в рамках дальнейших исследований.По результатам проведенного скрининга показано, что штамм Lb,paracasei 4.2 проявил высокую экзополисахарид-продуцирующую активность.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of studying the technological properties and the ability to synthesize exopolysaccharides of lactic acid bacteria isolated from domestic traditional fermented milk products. The strains were identified using the MALDI-TOF MS and API 50CHL methods. All tested strains showed the ability to grow in milk. After 24 hours of incubation, they formed a homogeneous, dense consistency, reminiscent of yogurt, and had a pleasant aroma characteristic of fermented dairy products. It should be noted that, according to technological parameters, the strains Lactobacillus acidophilus 3.7 and Lactobacillus acidophilus 3.10 demonstrated the best results: the total number of cells was 3.6 ± 2.3 × 10⁸ and 1.8 ± 4.0 × 10⁹ CFU/ml, respectively, and the pH values were 3.6 and 3.7. It was found that of the nine cultures studied, eight strains showed positive exopolysaccharide – producing activity. These strains were selected for the subsequent assessment of probiotic properties for their use in further research.According to the results of the screening, it was shown that the Lb strain, paracasei 4.2, showed high exopolysaccharide-producing activity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экзополисахариды</kwd><kwd>молочнокислые бактерий</kwd><kwd>пробиотические свойства</kwd><kwd>пребиотические свойства</kwd><kwd>скрининг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>exopolysaccharides</kwd><kwd>lactic acid bacteria</kwd><kwd>probiotic properties</kwd><kwd>prebiotic properties</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы выражают благодарность «Министерству науки и высшего образования Республики Казахстан» за финансовую поддержку научного, научно-технического проекта AP 22685499 «Потенциал применения экзополисахаридов пробиотических молочнокислых бактерий в пищевой биотехнологии» грантового финансирования исследований молодых ученых по проекту «Жас ғалым» на 2024-2026 годы.</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">Sandford P.A.
