WGA of metagenome: negative control of DNA extraction with VLP-e workflow
Paired-end sequencing libraries were prepared from the extracted DNA using the TruSeq DNA Nano kit (Illumina, CA, USA) followed by sequencing on the Illumina NextSeq 500, with a NextSeq 500/550 High Output Reagent kit v2 (300 cycles), in accordance with the standard Illumina sequencing protocols.
