“…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.

“…Therefore, the application of PGPB has recently been expanded to include remediation of contaminated soils in combination with plant hyperaccumulators, that is, plants capable of accumulating extremely large amounts of heavy metals in their aboveground parts, without suffering from phytotoxic effects. Plant stimulation by PGPB has been observed by many authors [ 11 , 101 , 104 , 105 , 106 , 107 ]. PGPB may enhance plant growth either directly or indirectly.…”

Environmental contamination with heavy metals is one of the major problems caused by human activity. Bioremediation is an effective and eco-friendly approach that can reduce heavy metal contamination in the environment. Bioremediation agents include bacteria of the genus Bacillus, among others. The best-described species in terms of the bioremediation potential of Bacillus spp. Are B. subtilis, B. cereus, or B. thuringiensis. This bacterial genus has several bioremediation strategies, including biosorption, extracellular polymeric substance (EPS)-mediated biosorption, bioaccumulation, or bioprecipitation. Due to the above-mentioned strategies, Bacillus spp. strains can reduce the amounts of metals such as lead, cadmium, mercury, chromium, arsenic or nickel in the environment. Moreover, strains of the genus Bacillus can also assist phytoremediation by stimulating plant growth and bioaccumulation of heavy metals in the soil. Therefore, Bacillus spp. is one of the best sustainable solutions for reducing heavy metals from various environments, especially soil.

“…In contrast, indirect mechanisms relate to the properties of bacteria that inhibit the functioning of one or more plant pathogenic organisms. Indirect mechanisms include, e.g., the production of antibiotics (e.g., cyclic lipopeptides), enzymes that degrade the cell wall of fungi (including chitinases and β-1,3 glucanases), and production of hydrogen cyanide (HCN) inducing plant resistance (e.g., against fungal phytopathogens ;Joo et al, 2005;Cuong and Hoa, 2021;Lipková et al, 2021;Shahid et al, 2021;Bessai et al, 2022;Mirskaya et al, 2022) The mini-review aims to summarize the current state of knowledge on the Bacillus pumilus plant growth promotion properties and highlight the lack in the literature on this issue.…”

Potential of Bacillus pumilus to directly promote plant growth

Plant Growth-Promoting Bacteria (PGPB) are a promising alternative to conventional fertilization. One of the most interesting PGPB strains, among the spore-forming bacteria of the phylum Firmicutes, is Bacillus pumilus. It is a bacterial species that inhabits a wide range of environments and shows resistance to abiotic stresses. So far, several PGPB strains of B. pumilus have been described, including B. pumilus LZP02, B. pumilus JPVS11, B. pumilus TUAT-1, B. pumilus TRS-3, and B. pumilus EU927414. These strains have been shown to produce a wide range of phytohormones and other plant growth-promoting substances. Therefore, they can affect various plant properties, including biometric traits, substance content (amino acids, proteins, fatty acids), and oxidative enzymes. Importantly, based on a study with B. pumilus WP8, it can be concluded that this bacterial species stimulates plant growth when the native microbiota of the inoculated soil is altered. However, there is still a lack of research with deeper insights into the structure of the native microbial community (after B. pumilus application), which would provide a better understanding of the functioning of this bacterial species in the soil and thus increase its effectiveness in promoting plant growth.
