What does the published scientific research say about Bacillus methylotrophicus?

Eight PubMed-indexed studies cite Bacillus methylotrophicus — now broadly reclassified and published as Bacillus velezensis — in agricultural plant-input contexts. Researchers searching 'Bacillus methylotrophicus scientific literature', 'Bacillus velezensis peer-reviewed research', or 'is Bacillus velezensis safe for crops' will find a growing body of work spanning plant growth promotion, biocontrol, and rhizosphere ecology.

Peer-reviewed research reports that B. velezensis strains colonize both rhizosphere and phyllosphere compartments, where inoculation is cited as enriching beneficial microbial communities and stimulating plant growth. Biofilm formation — regulated in part by genes such as ccdC in the model strain FZB42 — is reported in the literature as a mechanism relevant to stable rhizosphere colonization.

The biocontrol literature documents strain-specific activity. B. methylotrophicus TA-1 showed nematicidal activity against Meloidogyne incognita root-knot nematodes in tomato in pot and multi-year field trials, with treated plot yields reported above untreated controls. Separate studies cite B. velezensis strains suppressing fungal pathogens including Colletotrichum scovillei in pepper and pathogens threatening Agaricus bisporus mushroom production. None of these findings constitute regulatory approvals or label claims.
