В связи с высокой востребованностью в бактериальной наноцеллюлозе в различных отраслях промышленности исследования параметров, обеспечивающих высокий выход, являются актуальными. К основным параметрам, влияющим на рост целлюлозосинтезирующих бактерий и биосинтез бактериальной наноцеллюлозы, можно отнести: концентрацию источника углерода в питательной среде; аэрацию; температуру культивирования; уровень активной кислотности. Концентрация редуцирующих веществ в питательной среде может находится в диапазоне от 6 до 100 г/л. Концентрацию растворенного кислорода в питательной среде можно считать лимитирующим фактором для всех целлюлозосинтезирующих микроорганизмов. Температурный диапазон для биосинтеза бактериальной наноцеллюлозы у разных продуцентов может варьировать от 25 до 33 °С. Диапазон pH, обеспечивающий наибольший выход бактериальной наноцеллюлозы, для разных продуцентов изменяется от 4 до 6,5. Обзор литературы показал необходимость подбора условий культивирования, обеспечивающих максимальный выход бактериальной наноцеллюлозы для каждого продуцента отдельно.</p></abstract><trans-abstract xml:lang="en"><p>This paper describes conditions for the cultivation of bacterial nanocellulose using various primary producers. Research into parameters determining a high yield in the production of bacterial nanocellulose is highly relevant due to an increased demand in this product in various industries. Key parameters that affect the growth of cellulose-synthesizing bacteria and the biosynthesis of bacterial nanocellulose include the following: the concentration of the carbon source in the nutrient solution; aeration; cultivation temperature; active acidity level. The concentration of reducing substances in the nutrient solution can range from 6 to 100 g/l. The concentration of dissolved oxygen in the nutrient solution can be considered as a limiting factor for all cellulose-synthesizing microorganisms. It is shown that the temperature range for the bacterial nanocellulose biosynthesis can vary from 25 to 33°C for various primary producers. PH values that provide a maximal yield of bacterial nanocellulose are determined to range from 4 to 6.5 for various primary producers. The literature review has proven the importance of a case-by-case approach when selecting cultivation conditions for every primary producer so as to maximize the bacterial nanocellulose yield.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бактериальная наноцеллюлоза</kwd><kwd>продуцент</kwd><kwd>выход продукта</kwd><kwd>аэрация</kwd><kwd>температура</kwd><kwd>уровень активной кислотности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bacterial nanocellulose</kwd><kwd>cellulose-producing bacterium</kwd><kwd>product yield</kwd><kwd>aeration</kwd><kwd>temperature</kwd><kwd>pH level</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lin S.-P., Calvar I.L., Catchmark J.M., Liu J.-R., Demirci A., Cheng K.-C.
