GSM6801677: KO.2; feces metagenome; OTHER
Total genome DNA from samples was extracted using CTAB/SDS method. DNA concentration  and purity was monitored on 1% agarose gels, DNA was diluted to l ug/μL using sterile water, and then amplified. Sequencing libraries were generated using TruSeq® DNA PCR-Free Sample Preparation Kit  (Illumina, USA) following manufacturer's recommendations and index codes were added.
