| Research Abstract |
Three kinds of bacteria were isolated from arbuscular mycorrhizal spores and identified as Bacillus sp., Bacillus thuringiensis, and Paenibacillus rhizospherae. These bacteria also functioned on biocontrol of soil-borne plant pathogens Fusarium oxysporum, Rosellinia necatrix, Rhizoctonia solani and Pythium ultimum. Moreover, they were effective on phosphorus solubilization, ethylene production, nitrogenase activity, and stimulation of mycorrhizae hyphal growth in vitro. In addition, fresh samples of spores and hyphae were photographed using an in situ scanning electron microscope, where some bacterial slimes were detected on hyphae and spores.
