Из корневых клубеньков Vigna radiate, Vigna unguiculata и Vigna angularis, взятых из почв Дальнего Востока Российской Федерации, выделено и оставлено для дальнейших исследований 76 штаммов ризобий, отличающихся по своим физиолого-биохимическим характеристикам от B. jponicum и S. fredii.Методы. Вирулентность новых штаммов ризобий, выделенных в чистую культуру из клубеньков различных зернобобовых культур, определяли методом выращивания бактеризованных семян в пробирках диаметром 20 мм и высотой 200 мм с питательной средой для растений следующего состава, г/л: К2НРО4 — 1,0; МgSO4 — 1,0; CaSO4 — 0,5; FeSO4, H3BO3, MnSO4 и (NН4)6Мо7О24 — следы. По наличию клубеньков определяли вирулентность, а по их количеству — интенсивность образования клубеньков за счет изучаемого штамма. Определение первичной оценки внутренней устойчивости штаммов к антибиотикам проводили диско-диффузионным методом. В работе использовали антибиотики: налидиксовую кислоту (30 мкг), карбенициллин (100 мкг), стрептомицин (10 мкг), эритромицин (15 мкг), рифампицин (5 мкг), тетрациклин (30 мкг). После 3–7 дней инкубации при температуре +27…28 °C проводили учет результатов по диаметру зоны подавления роста штамма: до 10 мм — резистентные (R); от 10 до 15 мм — умеренно резистентные (I); от 15 до 25 мм — чувствительные (S); свыше 25 мм — высокочувствительные (HS).Результаты. Установлено, что у большинства штаммов отмечена резистентность к стрептомицину, эритромицину, рифампицину и налидиксовой кислоте, а наибольшая чувствительность отмечена к тетрациклину и карбенициллину. Штаммы могут быть отнесены к виду Bradyrhizobium elkanii.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. 76 rhizobia strains differing in their physiological and biochemical characteristics from B. japonicum and S. fredii were isolated from the root nodules of Vigna radiate, Vigna unguiculata and Vigna angularis, taken from the soils of the Far East of the Russian Federation, and left for further research.Methods. The virulence of new rhizobia strains isolated into a pure culture from nodules of various leguminous crops was determined by growing bacterized seeds in test tubes (height — 200 mm, diameter — 20 mm) with a nutrient medium for plants of the following composition, g/l: K2НРО4 — 1.0; МgSO4 — 1.0; CaSO4— 0.5; FeSO4, H3BO3, MnSO4, and (NН4)6Мо7О24 — traces. The virulence was determined by nodule presence; intensity of nodule formation due to the strain studied was determined by the nodule number. Primary assessment of the inherent strain resistance to antibiotics was performed with the disk diffusion test. Antibiotics used for the research: nalidixic acid (30 μg), carbenicillin (100 μg), streptomycin (10 μg), erythromycin (15 μg), rifampicin (5 μg), tetracycline (30 μg). After 3 to 7 days of incubation at a temperature of +27…28 °C, the results were registered according to the diameter of the strain growth suppression zone: up to 10 mm — resistant (R); 10 to 15 mm — intermediary resistant (I); 15 to 25 mm — sensitive (S); over 25 mm — highly sensitive (HS).Results. It was found that most strains were resistant to streptomycin, erythromycin, rifampicin, and nalidixic acid, while the highest sensitivity was noted to tetracycline and carbenicillin. Strains can be attributed to the Bradyrhizobium elkanii species.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>корневые клубеньки</kwd><kwd>ризобии</kwd><kwd>вигна</kwd><kwd>антибиотики</kwd><kwd>резистентность</kwd><kwd>инокуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>root nodules</kwd><kwd>rhizobia</kwd><kwd>vigna</kwd><kwd>antibiotics</kwd><kwd>resistance</kwd><kwd>inoculation</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">Zabaloy M.C., Gomez M.A. Diversity of rhizobia isolated from an agricultural soil in Argentina based on carbon utilization and effects of herbicides on growth.
