Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

В статье приведены результаты исследования биосовместимости мутантных штаммов клубеньковых и PGPR бактерий (ризобактерий) с целью их совместного применения для культур маша и фасоли. По результатам проведенных исследований определены штаммы, проявившие контактную прогрессию и нейтралитет - Pseudomonas putidaМ-1 и Phyllobacterium sp. 35М; штаммы Bacillus subtilis М-2 и Chryseobacterium rhizoplanae 1М оказались наиболее перспективными в отношении совместного культивирования.Таким образом, подобраны консорциумы на основе мутантных штаммов азотфиксирующих и ростостимулирующих бактерий Pseudomonas putida М-1 и Chryseobacterium rhizoplanae для растений маша и Bacillus subtilis М-2 и Phyllobacterium sp. 35М - для растений фасоли. Полученные результаты открывают возможность комбинирования мутантных штаммов PGPR с ростостимулирующей активностью (Pseudomonas putida М-1, Bacillus subtilis М-2) и клубеньковыхбактерий (Phyllobacterium sp. 35М, Chryseobacterium rhizoplanae) с азотфиксирующей активностью с целью получения на их основе биопрепарата с сочетанными свойствами. The article presents the results of a study of the biocompatibility of mutant strains of nodule and PGPR bacteria with the aim of their combined use for mung bean and beans. According to the results of the studies, the strains that showed contact progression and neutrality were identified - Pseudomonas putida M-1 and Phyllobacterium sp. 35M; strains Bacillus subtilis M-2 and Chryseobacterium rhizoplanae 1M proved to be the most promising for co-cultivation. Thus, consortia were selected based on mutant strains of nitrogen-fixing and growth-stimulating bacteria Pseudomonas putida M-1 and Chryseobacterium rhizoplanae for mung bean and Bacillus subtilis M-2 and Phyllobacterium sp.35M for bean plants. The results obtained open up the possibility of combining mutant PGPR strains with growth-stimulating activity (Pseudomonas putida M-1, Bacillus subtilis M-2) and nodule bacteria with nitrogen-fixing activity (Phyllobacterium sp. 35M, Chryseobacterium rhizoplanae) in order to obtain a biological product with combined properties on their basis.
