   <abstract xml:lang="ru">
    <p>Бактериальная целлюлоза обладает специфическими и уникальными свойствами, которые отличают ее от растительной. Она имеет высококристаллическую наноструктуру, высокую чистоту (отсутствие лигнина и гемицеллюлозы) и более высокую степень полимеризации, что делает ее перспективной альтернативой растительной целлюлозе для специфических применений. Для того, чтобы получить бактериальную целлюлозу с заданными физико-химическими характеристиками, необходимо тщательно исследовать способность ее продуцента метаболизировать различные источники углерода и их влияние на качество синтезированной целлюлозы. Целью данного исследования являлось изучение влияния состава питательной среды, включая источники углерода, витамины, минеральные соли и кислоты, на продуктивность и свойства бактериальной целлюлозы.&#13;
Объекты исследования – уксуснокислые бактерии Acetobacterium xylinum B-12429 (национальный биоресурсный центр ВКПМ). Культуру выращивали при температуре 28 °C в течение 72 ч на питательной среде Хестрина-Шрамма в присутствии различных источников углерода, а также дополнительных факторов роста в статических условиях при периодическом культивировании. Структурные характеристики полученных пленок бактериальной целлюлозы были изучены с помощью инфракрасной спектроскопии и сканирующей электронной микроскопии (СЭМ). Оценивали физико-химические характеристики бактериальной целлюлозы, включая водоудерживающую способность и индексы кристалличности (Iα и Iβ).&#13;
Максимальное накопление биомассы бактериальной целлюлозы на среде Хестрина-Шрамма происходило на 10 сутки культивирования в статических условиях. Наибольший выход бактериальной целлюлозы (4,4 г/л) получен с использованием фруктозы в качестве источника углерода с концентрацией 20,0 г/л. При использовании в качестве источника углерода глюкозы продуктивность бактериальной целлюлозы ниже (3,6 г/л). На продуктивность бактериальной целлюлозы оказывала влияние концентрация основного источника углерода: 10 % концентрация способствовала ее максимальному выходу. Внесение дополнительных компонентов в состав питательной среды, таких как аскорбиновая кислота и MgSO4, эффективно влияет на продуктивность синтеза бактериальной целлюлозы. Биопленки бактериальной целлюлозы, полученные на среде HS с ксилозой и сорбитом, обладали наибольшей водоудерживающей способностью. Индексы кристалличности для всех образцов бактериальной целлюлозы были приблизительно равны 1, что свидетельствует о стабильной кристаллической структуре целлюлозы независимо от источника углерода в питательной среде.&#13;
Исследование показало, что состав питательных сред оказывает значительное влияние на биосинтез бактериальной целлюлозы. Эти результаты подчеркивают важность оптимизации состава питательных сред для повышения продуктивности ее биосинтеза, что может быть использовано в промышленности для получения высококачественной бактериальной целлюлозы.</p>

    <p>Bacterial cellulose differs from plant cellulose: its unique properties include a strong crystalline nanostructure and a high degree of polymerization. In addition, it is more pure than traditional cellulose as it contains neither lignin nor hemicellulose. These qualities make it a promising alternative to plant cellulose in several industries. Bacterial cellulose with the specific physicochemical profile can be obtained only if the metabolizing properties of its producer have been considered. This article describes the effect of nutrient medium compositions with different carbon sources, vitamins, mineral salts, and acids on the yield and properties of bacterial cellulose.&#13;
Acetic acid bacteria Acetobacterium xylinum B-12429 were cultivated statically at 28°C for 72 h on the Hestrin-Schramm medium with varying carbon sources and growth factors.&#13;
The highest biomass yield (4.4 g/L) was obtained on cultivation day 10 in the sample with 20.0 g/L fructose. Glucose provided a lower productivity of 3.6 g/L. The bacterial cellulose yield also proved to depend on the concentration of the main carbon source: it was at its maximum at 10%. Adding ascorbic acid and MgSO4 also catalyzed the biosynthesis. The structural profile was studied using infrared spectroscopy and scanning electron m icroscopy. It included such physicochemical properties as water-holding capacity and crystallinity indices Iα and Iβ. The biofilms produced from the media fortified with xylose and sorbitol demonstrated excellent water-holding capacity; all the samples demonstrated a stable crystalline structure regardless of the carbon source.&#13;
The composition of the nutrient media had a significant effect on the yield and quality of biosynthesis. An optimized nutrient composition was able to boost biosynthesis, making the method applicable to industrial scales of high-quality bacterial cellulose production.</p>
