Проведено исследование биоразнообразия микроорганизмов, и определены физиологические и биохимические свойства бактериальных штаммов, способных к окислению углеводородов, выделенных из донных отложений северной части Японского моря для двух районов: с обнаруженными газовыми гидратами (район 1) и без присутствия газовых гидратов (район 2). Комплексные газогеохимические, геологические и микробиологические исследования проведены на акватории северной части Японского моря – южной части Татарского пролива, и северного склона Приморского края.</p><p>Использованы материалы морских экспедиций: НИС «Академик Опарин» № 54 (OP54, сентябрь – октябрь 2017 г.) и НИС «Академик М.А. Лаврентьев» № 81 (LV81, май 2018 г.). Используя методы культивирования, выявлено, что представители семейства Nocardiaceae типа Actinomycetota привязаны к местам обнаружения газовых гидратов. Показано, что бактерии, выделенные из района с обнаруженными газовыми гидратами, проявляли способность ферментировать более широкий спектр углеводных субстратов по сравнению с культурами, полученными из негазогидратного района. Отмечена положительная корреляция между способностью к деструкции карбоновых кислот и отсутствием газогидратов.</p></abstract><trans-abstract xml:lang="en"><p>Our research deals with the possibilities of using microorganisms as bioindicators for methane ecosystems in areas with gas hydrates. We have conducted a study of the biodiversity of microorganisms and determined the physiological and biochemical properties of bacterial strains that can oxidize hydrocarbons isolated from the bottom sediments in the northern part of the Japan Sea for two areas: one with detected gas hydrates (Area 1) and one without the presence of gas hydrates (Area 2). Complex gas-geochemical, geological, and microbiological studies have been conducted in the waters of the northern Japan Sea, including the southern part of the Tatar Strait and the northern slope of Primorsky Krai. Obtained materials were gotten from marine expeditions: RV “Akademik Oparin” 54 (OP54) in September–October 2017 and RV “Akademik M.A. Lavrentyev” 81 (LV81) in May 2018. We used cultivation techniques to discover that members of the Nocardiaceae family from the Actinomycota phylum were associated with areas where gas hydrates had been detected. We found that bacteria isolated from these areas were able to ferment a wider variety of carbohydrate substrates than those obtained from non-gas hydrate areas. A positive correlation was observed between the ability of these bacteria to break down carboxylic acids and their absence from gas hydrate-rich environments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метан</kwd><kwd>газовые гидраты</kwd><kwd>деструкция углеводородов</kwd><kwd>донные отложения</kwd><kwd>физиолого-биохимические свойства</kwd><kwd>Японское море</kwd><kwd>Татарский пролив</kwd></kwd-group><kwd-group xml:lang="en"><kwd>methane</kwd><kwd>gas hydrates</kwd><kwd>hydrocarbon degradation</kwd><kwd>bottom sediments</kwd><kwd>physiological and biochemical properties</kwd><kwd>Japan Sea</kwd><kwd>Tatar Strait</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работы, связанные с проведением экспедиций, осуществлены при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках государственного задания ТОИ ДВО РАН № 124022100078-7.
