What benefits of Bacillus cereus have been cited in the scientific literature?
Peer-reviewed research on Bacillus cereus documents 22 benefit categories relevant to potential biostimulant and biocontrol label claims. Cited growth-promotion mechanisms include IAA production, ACC deaminase activity, phosphate solubilization, siderophore synthesis, and production of gibberellin and organic acids. Studies report increased plant height, root length, biomass, and N/P/K uptake in soybean, maize, rice, and wheat.
The literature cites Bacillus cereus for broad-spectrum biocontrol activity. Research reports suppression of bacterial pathogens (Pseudomonas syringae, Ralstonia solanacearum), fungal pathogens (Fusarium oxysporum, Botrytis cinerea, Rhizoctonia solani), and the nematode Meloidogyne incognita — including reported 100% second-stage juvenile mortality within 12 hours and reduction of Fusarium wilt incidence in tomato from 96% to 12% under greenhouse conditions. Induced systemic resistance via camalexin priming, extracellular enzymes, and antibiotic lipopeptides are also cited.
1Potential claims from the literature
