title: Uncontaminated control soil (CK1) microbial community metagenomic sequencing, Replicate 3
design: This sample is an uncontaminated control soil (CK1), one of 3 biological replicates for the CK1 group. The group was set to provide a baseline reference for microbial community structure in non-polluted agricultural soil. Total genomic DNA was extracted from the soil sample, and metagenomic sequencing was performed on the Illumina NovaSeq 6000 platform (paired-end reads) to compare with Cd-Pb contaminated soil groups.
