- Observation Bacillus subtilis produced IAA, siderophore, HCN, extracellular compounds and volatile antibiotics in vitro.
- Observation Bacillus megaterium produced IAA, siderophore, HCN, extracellular compounds and volatile antibiotics in vitro.
- Observation Both PGPR strains produced chitinase, β-1, 3-glucanase and protease in growth media.
- Observation Bacillus megaterium produced more secondary metabolites than B. subtilis.
