Microbial transformation of organic matter of sod-podzolic soils in the Pre-Urals under conditions of different use and application of mineral fertilizers

N.E. Zavyalova, I.G. Shirokikh, A.I. Kosolapova & A.A. Shirokikh
Microbiological parameters and character of transformation of humic substances of sod-podzolic soil at the end of five rotations of eight-full crop rotation in long-term stationary field experiment (1978–2017) are investigated. The direction of microbiological processes due to the effect of long-term application of mineral fertilizers in increasing doses – 30 to 150 kg/ha of NPK was determined. A comparison of the arable soil with its virgin analogs (mixed forest and natural meadow) as well as...

Identification and study of the properties of Streptomyces geldanamycininus 3K9, isolated from the soil under the bush of Heracleum sosnowskyi

E.V. Tovstik, A.V. Sazanov, А.V. Bakulina, I.G. Shirokikh & T.Ya. Ashikhmina
The antagonistically active bacterial strain 3K9 was isolated from the soil under the thickets of the invasive Heracleum sosnowskyi Manden. species. Identification of the 3K9 strain was performed using cultural morphological traits, as well as based on the analysis of a fragment of the 16S rRNA gene. The greatest similarity (98.54%) of the nucleotide sequence of the 3K9 strain to the nucleotide sequence of Streptomyces geldanamycininus NRRL 3602 (Accession number NCBI NR_043722.1) was established. Macbecin...

Optimization of the microbiological composition of the biological product for cultivation of Lotus corniculatus

L.I. Domracheva, D.V. Kozylbayeva, A.L. Kovina, L.V. Trefilova, Yu.N. Zykova, M.N. Gripas & V.A. Izotova
In a field experiment the effectiveness of presowing treatment of seeds of Lotus corniculatus by mono- and multicomponent microbial associations has been investigated. The associations were based on the nodule bacteria (NB) of Rhizobium loti, cyanobacteria (CB) Fischerella muscicola and actinobacteria (AB) Streptomyces hygroscopicus A4. Evaluation of effectiveness was carried out by the analysis of morphometric parameters of the aerial part and the plants biomass, as well as the intensity of the tubercles formation. The...

Testing the stability of different forms of Hordeum vulgare L. to the toxic action of aluminum

N.V. Kononenko, I.A. Chaban, E.A. Smirnova, I.G. Shirokikh, O.N. Shupletsova & E.N. Baranova
Combined effect of aluminum toxicity and acidic soil conditions is the major problem for barley productivity in certain areas of crop cultivation. Therefore the development of effective test systems for the identification and selection of aluminum-resistant barley genotypes is an important goal, especially for regions all over the world with high soil acidity. We used barley genotypes with different resistance to ionic toxicity (Belgorodsky 100, Belogorsky, Kupets, Elo, 999-93 and regenerant line 917-01) for characterization...

Идентификация двух ризосферных изолятов стрептомицетов и изучение in vitro их колонизирующей активности

Я.И. Назарова, И.Г. Широких, А.В. Бакулина, Е.Н. Баранова & Т.Я. Ашихмина
Разработка экологически безопасных биологических препаратов для защиты сельскохозяйственных культур от поражения вредоносными грибами и бактериями имеет особую актуальность в связи с массовым заселением пахотных почв Российской Федерации токсигенными и фитопатогенными микроорганизмами. Из ризосферы растений семейства Solаnacea – томата (Solanum lycopersicum L.) и табака (Nicotiana tabacum L.)– были изолированы два штамма актинобактерий, один из которых проявил фиторегуляторное (ТК-5), другой – антагонистическое действие в отношении тест-культур грибов и бактерий (Т-2-20). По результатам секвенирования фрагмента гена 16S рРНК...
