What does the published scientific research say about Bacillus aryabhattai?

Eight PubMed-indexed studies reference Bacillus aryabhattai — also classified as Priestia aryabhattai — as a plant growth-promoting rhizobacterium (PGPR). Strains have been isolated from saline soils, long-term maize-colonized fields, tomato rhizospheres, and saline rice paddies in Bangladesh, with the literature characterizing it as a biofertilizer candidate for sustainable agriculture.

Peer-reviewed research consistently reports phosphate solubilization, nitrogen fixation, siderophore production, and indole-3-acetic acid (IAA) biosynthesis across characterized strains. Whole-genome analysis of strain MS3 identified additional gene clusters linked to potassium solubilization, phytohormone biosynthesis, and secondary metabolites including surfactin and koranimine.

Reported crop outcomes in the scientific literature include increased maize shoot and root length (strain LAD), improved zinc and iron concentrations in wheat grain (strain S10), enhanced tomato biomass in greenhouse trials (strain VMYP6), and alfalfa growth promotion associated with rhizosphere carbon-sequestration shifts. Arabidopsis and tobacco inoculation trials identified novel transcriptomic changes involving gibberellin-regulated and auxin-related gene expression during endophytic colonization.

Several strains exhibit salt and drought tolerance in laboratory characterization, informing research interest in Priestia aryabhattai for stress-prone growing environments. These are findings cited in peer-reviewed research — no regulatory registrations or approved label claims are represented in this literature data.
