What benefits of Bacillus methylotrophicus have been cited in the scientific literature?
Bacillus methylotrophicus — also classified as Bacillus velezensis — appears in the peer-reviewed literature as a candidate biocontrol agent, with three documented benefit categories relevant to growers researching biological nematicide options.
All three findings come from studies using strain TA-1. In vitro, that strain exhibited nematicidal activity against second-stage juveniles and eggs of Meloidogyne incognita, with LC50 values of 5.80 and 7.00 × 10⁸ CFU/ml respectively. Researchers asking 'does Bacillus methylotrophicus control root-knot nematode' will find this the primary evidence base.
