title: Metagenomic sequencing of microcosm F4_2: sediments with high PCB concentration
design: DNA was sheared with the Covaris E220 ultrasonicator (Covaris, Inc., Woburn, MA, USA) to an average size of 550 base pairs and indexed libraries prepared with the Roche Kapa HyperPrep kit. DNA libraries were sequenced on an S Prime Illumina Novaseq 6000 (2x150 bp PE) flow cell.
