Изолят Ср-1 способен солюбилизировать фосфаты с образованием зон «гало» 9 мм, а изолят СА-6 обладает нитрогеназной активностью 44,0 нМ С2Н2/фл/3 сут. Изоляты Ср-1 и СА-6 являются ростстимулирующими микроорганизмами, что обусловлено их способностью синтезировать индолил-3-уксусную кислоту (ИУК) в концентрациях 89,7 и 37,8 мкг ИУК/мл культуральной жидкости соответственно. Отобранные солеустойчивые изоляты были идентифицированы на основании анализа нуклеотидной последовательности гена 16S рРНК и MALDI-TOF масс-спектрометрии и отнесены к видам Rhodococcus jostii и Priestia megaterium. Солеустойчивые штаммы Priestia megaterium Ср-1 и Rhodococcus jostii СА-6 депонированы в Белорусской коллекции непатогенных микроорганизмов под номерами БИМ В-1314Д и БИМ В-1353Д соответственно.</p></abstract><trans-abstract xml:lang="en"><p>315 variants of halotolerant bacteria were isolated from soil samples taken around Starobin potash deposit mined by Belaruskali concern. Nitrogen-fixing isolate CA-6 and phosphate-solubilizing isolate Cp-1 capable to withstand abiotic stress caused by sodium chloride in concentration 1710 and 2565 mM, respectively and water deficiency characterized by osmotic potential -0.20 and -0.42 MPa were sorted out. Isolate Cp-1 may dissolve phosphates yielding halo zones 9 mm in diameter while isolate CA-6 displays nitrogenase activity 44.0 nM C2H2/vial/3 days. Both isolates are growth-promoting organisms, distinguished by the ability to synthesize IAA in concentrations 89.7 and 37.8 μg IAA/ml of cultural liquid, respectively. The selected salt-resistant isolates were identified based on analysis of the nucleotide sequence of the 16S rRNA gene and data of MALDI-TOF mass spectrometry and were referred to the species Rhodococcus jostii and Priestia megaterium. Halotolerant strains Priestia megaterium Cp-1 and Rhodococcus jostii CA-6 were deposited in Belarusian collection of non-pathogenic microorganisms under the respective registration numbers BIM B-1314D and BIM B-1353D.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>солеустойчивость</kwd><kwd>азотфиксация</kwd><kwd>фосфатсолюбилизация</kwd><kwd>ростстимуляция</kwd><kwd>идентификация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>salt resistance</kwd><kwd>nitrogen fixation</kwd><kwd>phosphate solubilization</kwd><kwd>growth stimulation</kwd><kwd>identification</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского республиканского фонда фундаментальных исследований (проект № Б17АРМ-044).
