Archea_ Feammox enrichment 200
The archeal informative region of 16S was amplified using Arch349F: CCCTACGGGGTGCASCAG Arch806R: GGACTACVSGGGTATCTAAT primers. The amplicons were purified, quantified, pooled, and then sequenced on the NovaSeq 6000 platform (Illumina, USA), in 250 pair-end (PE) mode. Quantification of the amplicons was performed on the Qubit 4 fluorimeter (Invitrogen, USA).
