title: WGS_AgNP_12W_2
design: The pooled biofilm biomass was subjected to genomic DNA (gDNA) extraction using a Quick-DNATM Fecal/Soil Microbe Miniprep Kit (ZYMO, CA, USA) according to the manufac- turers instructions. DNA samples were sent to Novogene (Beijing, China) for 16S rRNA gene and metagenome sequencing on Illumina NovaSeq
