“…Members of the Sphingomonas genus are bacteria with iron-carrying properties and nitrogen-fixing capabilities [31]. Studies have shown that increased iron carriers and nitrogen content can promote the pathogenicity of pathogens [41,42]. However, bacteria belonging to the Mucilaginibacter genus can help promote plant growth, induce salt tolerance, and enhance cytoplasmic signals in plants [32].…”

Tomato pith necrosis (TPN) is a highly destructive disease caused by species of the Pseudomonas genus and other bacteria, resulting in a significant reduction in tomato yield. Members of the genus Bacillus are beneficial microorganisms extensively studied in the rhizosphere. However, in most cases, the potential of Bacillus members in controlling TPN and their impact on the rhizosphere microbial composition remain rarely studied. In this study, Bacillus velezensis ZN-S10 significantly inhibited the growth of Pseudomonas viridiflava ZJUP0398-2, and ZN-S10 controlled TPN with control efficacies of 60.31%. P. viridiflava ZJUP0398-2 significantly altered the richness and diversity of the tomato rhizobacterial community, but pre-inoculation with ZN-S10 mitigated these changes. The correlation analysis revealed that ZN-S10 maybe inhibits the growth of nitrogen-fixing bacteria and recruits beneficial bacterial communities associated with disease resistance, thereby suppressing the occurrence of diseases. In summary, the comparative analysis of the rhizosphere microbiome was conducted to explore the impact of ZN-S10 on the composition of rhizosphere microorganisms in the presence of pathogenic bacteria, aiming to provide insights for further research and the development of scientific and eco-friendly control strategies for this disease.

The object of research: morphological and cultural characteristics of micromycetes: yeast Saccharomyces cerevisiae and mycelial fungi Mucorracemosus grown on agar medium.The subject of research: flax seed suspension, ultrafine powder of double oxide of divalent and trivalent ferrum, micromycetes: yeast Saccharomyces cerevisiae and mycelial fungi MucorracemosusInvestigated problem: ensuring the bacteriostatic properties of raw materials and obtaining products with an extended dates of expiry.The subject in scientific results: the impact of nanoparticles (NP FeO×Fe2O3) on the bacteriostatic (protective) properties of flax seeds against fungal infections has been studied and the dependence of bacteriostatic properties on the amount of nanomagnetite has been determined. The ability of nanomagnetite to improve the bacteriostatic properties of flax seeds has been proven: addition of 0.1 %; 0.15 %; 0.2 % of nanomagnetite suppresses the development of microflora (micromycetes) in flax seed samples by 8–20 times. A reduction in the number of micromycetes (yeast Saccharomycescerevisiae and mycelial fungi Mucorracemosus) by 8–10 times and the size by 10–20 times was established compared to the control. The rational content of nanoparticles (NPs FeO×Fe2O3–nanomagnetite) has been determined as 0.15 % of the weight of the recipe mixture. The proposed mathematical model makes it possible to predict the effectiveness of using NP FeO×Fe2O3 – nanomagnetite to inhibit the growth of mycelial fungi to ensure the bacteriostatic properties of raw materials, in particular, flax seeds. The area of practical use of the research results: food industry enterprises specializing in the production of bakery and flour confectionery products using a mixture of wheat and rye flour with the addition of food additives. Innovative technological product: flour raw material with a mineral nano-additive suspension based on the double oxide of divalent and trivalent ferrum, which allows to ensure quality and extend dates of expiry of the product. Scope of the innovative technological product: to enhance the quality of food supply of the troops in extreme conditions

“…Therefore, nitrogen is usually applied at high concentrations in the form of an inorganic fertilizer. However, excessive fertilizer application in agricultural production results in many types of serious problems, including the breeding of soil-borne pathogens, soil acidification, loss of species diversity, and the release of greenhouse gases . The nitrogen immobilized in microbial biomass can be remineralized or transformed into a stable form, and root exudates can enrich different special rhizosphere microbial communities and respond to variations in species, genotype, and environment .…”

Microbiomes are the most important members involved in the regulation of soil nitrogen metabolism. Beneficial interactions between plants and microbiomes contribute to improving the nitrogen utilization efficiency. In this study, we investigated the Apiaceae medicinal plant Angelica dahurica var. formosana. We found that under a low-nitrogen treatment, the abundance of carbon metabolites in the rhizosphere secretions of A. dahurica var. formosana significantly increased, thereby promoting the ratio of C to N in rhizosphere and nonrhizosphere soils, increasing carbon sequestration, and shaping the microbial community composition, thus promoting a higher yield and furanocoumarin synthesis. Confirmation through the construction of a synthetic microbial community and feedback experiments indicated that beneficial plant growth-promoting rhizobacteria play a crucial role in improving nitrogen utilization efficiency and selectively regulating the synthesis of target furanocoumarins under low nitrogen conditions. These findings may contribute additional theoretical evidence for understanding the mechanisms of interaction between medicinal plants and rhizosphere microorganisms.
