The original habitat of the strain was anthropogenically salinated soil at the Verkhnekamsk deposit of potassium and magnesium salts (Perm krai, Russia). The strain grew within the temperature range from 5 to 35°C. At 5 and 32°C, the intracellular content of trehalose in the cells of <italic>Glutamicibacter</italic> sp. SMB32 was significantly higher than at 25°C. <italic>Glutamicibacter</italic> sp. SMB32 was able to grow both in the absence of NaCl and at its concentrations up to 11%. Glutamate predominated in the cells growth without NaCl. At high salinity (8% NaCl), predominant compounds in the studied strain cells were trehalose, proline, glutamine, and glutamate. Increasing salinity of the growth medium resulted in higher levels of intracellular proline. This is the first report of ability of a <italic>Glutamicibacter</italic> strain to synthesize mannitol; its accumulation was found to depend on the aeration mode. Thus, <italic>Glutamicibacter</italic> sp. strain SMB32 possesses high metabolic plasticity and is able to adapt to the action of unfavorable physicochemical factors.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324487680">Методом спектроскопии протонного магнитного резонанса исследован пул совместимых веществ, накапливающихся в ответ на действие абиотических факторов среды в клетках штамма <italic>Glutamicibacter</italic> sp. SMB32. Средой обитания исследованного штамма являлась техногенно засоленная почва района солеразработок Верхнекамского месторождения калийно-магниевых солей (Пермский край, Россия). Штамм SMB32 рос в диапазоне температур 5‒35°С. Выявлено, что при 5 и 32°С в клетках значительно увеличивалось количество трегалозы, чем при 25°С. <italic>Glutamicibacter</italic> sp. SMB32 был способен расти как без соли, так и в присутствии до 11% NaCl. В клетках, выращенных в среде без хлорида натрия, преобладал глутамат. В условиях высокой солености среды (8% NaCl) в клетках исследованного штамма доминировали трегалоза, пролин, глутамин и глутамат. Повышение солености среды культивирования приводило к возрастанию внутриклеточных количеств пролина. В представленной работе на примере штамма SMB32 впервые показана способность бактерий рода <italic>Glutamicibacter</italic> к синтезу маннита, и продемонстрирована зависимость его аккумуляции от режима аэрации<italic>.</italic> Таким образом, штамм <italic>Glutamicibacter</italic> sp. SMB32 обладает высокой пластичностью метаболизма, проявляя способность адаптироваться к неблагоприятному действию разных физико-химических факторов.</p></trans-abstract><kwd-group xml:lang="en"><kwd><italic>Glutamicibacter</italic></kwd><kwd>compatible solutes</kwd><kwd>NMR</kwd><kwd>temperature</kwd><kwd>salinity</kwd><kwd>aeration</kwd></kwd-group><kwd-group xml:lang="ru"><kwd><italic>Glutamicibacter</italic></kwd><kwd>совместимые вещества</kwd><kwd>ЯМР</kwd><kwd>температура</kwd><kwd>соленость</kwd><kwd>аэрация</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Настоящее исследование выполнено в рамках государственного задания АААА-А19-119112290008-4.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Василец Е.А.
