What benefits of Bacillus mycoides have been cited in the scientific literature?
Biocontrol literature on Bacillus mycoides includes foliar application reducing Watermelon Mosaic Virus (WMV) severity in squash by 87% in pot experiments, with WMV-infected plants showing gains in height and shoot dry weight relative to infected controls. Separately, the species is reported to produce styrene, a volatile nematicidal compound causing avoidance behavior and up to 90.94% mortality in Meloidogyne incognita root-knot nematode under pot conditions. In vitro work with vineyard-soil isolates also documents Bacillus mycoides suppressing growth and mycotoxin concentrations in Aspergillus carbonarius, A. niger, and A. flavus.
Research further reports Bacillus mycoides mitigating arsenic stress in spinach (Spinacia oleracea) via biosorption and intracellular transformation, and colonizing plant roots with occasional endophytic establishment. All of the above are benefits cited in peer-reviewed research — none represent approved label claims or regulatory endorsements.
1Potential claims from the literature
Reported to produce indole acetic acid (IAA), solubilize phosphate and zinc, produce ammonia, and exhibit ACC deaminase (ACCD) activity as plant growth-promoting traits
Reported to reduce Watermelon Mosaic Virus (WMV) disease severity in squash by 87% following foliar application in pot experiments
Reported to increase plant height and shoot dry weight in squash plants infected with WMV relative to infected controls
Reported to produce siderophores, indole acetic acid, catalase, oxidase, proteases, amylases, and lipases as plant growth-promoting traits when isolated from the gastrointestinal tract of Eisenia fetida
Reported to solubilize phosphate when isolated from the gastrointestinal tract of Eisenia fetida, suggesting potential as a microbial biofertilizer
Reported to possess plant growth-promoting attributes including phosphate solubilization, siderophore production, ammonia production, and nitrate reduction
Reported to mitigate arsenic stress in spinach (Spinacia oleracea) plants, with evidence of biosorption and intracellular arsenic transformation as tolerance mechanisms
Reported to produce styrene, a volatile nematicidal compound, which caused avoidance behavior and mortality in the root-knot nematode Meloidogyne incognita and the free-living nematode Caenorhabditis elegans
Reported to achieve up to 90.94% control efficiency against Meloidogyne incognita in pot experiments
Reported to colonize plant roots and occasionally establish an endophytic lifestyle, with potential as a plant biocontrol agent
Reported to reduce the growth and mycotoxin concentration of mycotoxigenic fungi (Aspergillus carbonarius, A. niger, and A. flavus) in vitro when isolated from ecological vineyard soils
Reported to be identified among microorganisms isolated from chickpea root nodules in a semiarid region, with all identified microorganisms noted as having significant potential to promote chickpea plant growth
