title: Metagenomics of arid soil microbial community: DNA-3-S1_S71
design: DNA was extracted from 250 mg of soil using the DNeasy PowerSoil Pro Kit.  DNA was sheared to 200 bp using an S2 sonicator  with standard conditions. Library preparation was performed using the NEBNext Ultra II DNA Library Prep Kit for Illumina with NEBNext Multiplex Oligos for Illumina UDI primer pairs. Paired-end sequencing (2x150 bp) was performed in a NovaSeq 6000
