Microbial conversion of organic nitrogenous wastewater to nitrate solution. bioreactor metagenome

A biological system to produce a high-quality nitrate solution for use in hydroponic fertilizer was developed. The system was found to have a stable and efficient performance in the conversion of organic nitrogen to nitrate. To determine the key microbes involved and better understand the system, the microbial communities in the reactors were analyzed by 16S rRNA gene sequencing in combination with a shotgun metagenomic analysis.
