Karst aquifer media microorganism Raw sequence reads. Karst aquifer media microorganism

Relative abundance of three keystone taxa, including ASV9 (Comamonas), ASV79 (Nitrospira) and ASV7 (Comamonadaceae), were positively correlated with numbers of soluble N-containing DOM denitrogenating reactions (E.g. ammonification) and relative abundance of nitrification. This research provided direct linkages of DOM molecular transformation to the microbial community and complex N cycle and transport in karst aquifers.
