Methanol oxidizing organisms not only reduce atmospheric methanol concentration but also play a major role in enhancing methane oxidation through cross-feeding in synergism with methanotrophs. Possession of plant growth promoting (PGP) attributes in methanol oxidizing bacteria will prove to be a worthy candidate for developing novel biofertilizers having dual ability of plant growth promotion and reducing methane emission to a certain extent. We are reporting 11 plant growth promoting methanol oxidizing bacteria belonging to the genera Rahnella, Serratia, Enterobacter and Pantoea of order Enterobacterales isolated from phyllosphere, rhizosphere and non-rhizosphere of flooded paddies. Among 11 isolates, Rahnella aquatilisANRf177 showed significantly highest growth in AMS broth having 0.5% methanol as the sole C source. R. aquatilis MaAL105 produced significantly higher IAA and showed maximum solubilization of P and K. Pantoea sp. KAAr216 showed significantly maximum N2 fixation ability and solubilization of Zn salts. These efficient methanol oxidizing bacteria having PGP attributes can be evaluated under field conditions.

Keywords: Methanol oxidizers, Enterobacterales, PGPR, P, K, Zn solubilization, N2- fixation, Indole Acetic Acid
