Abstract:
Organic hydroponic is one of a soilless crop cultivation technique and expected to be used instead of traditional agricultural practices. Organic hydroponics consists of the nitrification process, which is the enrichment process of the microbial community for mineralizing organic compounds and the crop cultivation process while maintaining the enriched nitrifying microbial community. The analysis of microbial consortia involved in ammonification and nitrification is required to enable us to develop microbial consortia useful for organic hydroponics.
In this study, nitrifying microbial consortia were enriched from various agricultural soils by regulating the amounts of organic nitrogen compounds and by controlling the aeration conditions. Repeated enrichment showed reproducible mineralization of organic nitrogen compounds via the conversion of ammonium ions (NH4+) and nitrite ions (NO2−) into nitrate ions (NO3−). The change in microbial compositions during the enrichment was investigated by sequence analysis based on 16s rDNA. The microbial transition showed the relation to nitrogen-ions transition. Some heterotrophic bacteria belonging to the genera of Bacillus and Pseudomonas were the major bacteria acting throughout the ammonification and nitrification. These results, which revealed representative microorganisms acting in each ammonification and nitrification stages, will be valuable for the development of a simple microbial consortia for organic hydroponics.
