“…Halophytic plants are the best model for the isolation of bacterial endophytes helping with the elimination of excess salt concentrations [ 43 , 44 , 45 , 46 , 47 ]. Many bacteria of the genus Bacillus are able to stimulate plant growth and provide protection under biotic and abiotic stresses [ 48 , 49 , 50 , 51 , 52 ].…”

Endophytic bacteria can be used to overcome the effect of salinity stress and promote plant growth and nutrient uptake. Bacillus safensis colonizes a wide range of habitats due to survival in extreme environments and unique physiological characteristics, such as a high tolerance for salt, heavy metals, and ultraviolet and gamma radiations. The aim of our study was to examine the salt resistance of the endophytic strain TS3 B. safensis and its ability to produce phytohormones and verify its effect on plant yield in field trials and the alleviation of salt stress in pot experiments. We demonstrate that the strain TS3 is capable of producing enzymes and phytohormones such as IAA, ABA and tZ. In pot experiments with radish and oat plants in salinization, the strain TS3 contributed to the partial removal of the negative effect of salinization. The compensatory effect of the strain TS3 on radish plants during salinization was 46.7%, and for oats, it was 108%. We suppose that such a pronounced effect on the plants grown and the salt stress is connected with its ability to produce phytohormones. Genome analysis of the strain TS3 showed the presence of the necessary genes for the synthesis of compounds responsible for the alleviation of the salt stress. Strain B. safensis TS3 can be considered a promising candidate for developing biofertilizer to alleviate salt stress and increase plant yield.

“…Os mesmos autores, avaliaram a eficiência agronômica em milho e também relataram crescimento semelhante em plantas adubadas com fontes naturais de fósforo e fertilizantes fosfatados solúveis. Timofeeva et al (2023) em um estudo de dois anos, analisou o uso de apatita combinado com vários microrganismos solubilizadores de P do gênero Bacillus para produção de azevém (Lolium multiflorum). Os autores relataram que o uso de concentrados de apatita incrementou o crescimento de azevém, porém a combinação do concentrado de apatita com microrganismos solubilizadores de P pode substituir fontes de P solúvel.…”

“…The genome analysis of strain BS89 revealed the presence of gene clusters responsible for the synthesis of plant-growth-promoting metabolites (indole 3-acetic acid [IAA] and volatiles), numerous hydrolytic enzymes, vitamins, and antimicrobial compounds (surfactin, fengycin, bacilysin, macrolactin, difficidin, bacillaene, and plantazolicin) [27]. It was also demonstrated that strain Bacillus velezensis BS89 can enhance the assimilation of minerals such as Ca and P [28].…”

Biomodified mineral fertilizers (BMFs) were produced by enriching the ammophos fertilizer with PGPR Bacillus velezensis BS89 with the use of two technologies: BMF 1, the ammophos fertilizer with the addition of spores of Bacillus velezensis BS89 on a dry carrier (diatomite); and BMF2, ammophos granules treated with spores of Bacillus velezensis BS89 in a cell suspension. The effects of BMFs on maize growth and productivity and the rhizosphere bacterial community were assessed. BMFs significantly increased maize growth, dry matter, minerals, starch and protein contents in maize grain. The application of biomodified mineral fertilizers resulted in the significant increase in the yield and some parameters of maize plants such as ear length and number of kernels in the row. The yield was increased by 7.5–7.6%, ear length by 9%, and number of kernels in the row by 6.7–7%, as compared with ammophos. However, we found no considerable differences in the composition of the bacterial community of the maize rhizosphere after the use of BMFs as compared with the use of ammophos at the level of the phyla, which was confirmed by the ecological indices of biodiversity: the Shannon index and the Simpson index. Comparison of the experimental variants with bulk soil showed differences in the microbiome composition of the dominant bacterial phyla. A greater abundance of Proteobacteria and Bacteroidetes and a lower abundance of Chloroflexi was registered in bulk soil as compared with the other experimental variants where maize plants were present. The highest percentage (5.3%) of unidentified taxonomic phyla was also found in bulk soil. Our studies showed that maize is the main structuring factor during formation of the microbiome composition in the rhizosphere. The application of biomodified fertilizers BMF1 and BMF2 considerably increased the abundance of bacteria representing the minority of the community, namely, those from the phyla Verrucomicrobia, Chloroflexi, Planctomycetes, Proteobacteria, Firmicutes and Chlamydiae, as compared with the use of ammophos. Thus, the application of biomodified mineral fertilizers is a promising agronomic and ecological strategy for boosting maize yield and the quality of grain under field conditions.
