| Outline of Final Research Achievements |
As results of metagenomic analysis, organic hydroponics microorganisms contains unique ecosystems that nitrifying bacteria account for about 1 percent of the rhizosphere microorganisms. Rhizosphere microorganisms are affected by plant species, they showed a unique microflora. Extracted compounds from rhizosphere microorganisms promotes the lateral root development, it was suggested that microorbanisms are involved significantly in the development of the roots. Pairs of microorganisms showed antagonism to phytopathogenic microorganisms, even if single microorganisms couldn't show antagonism.
