Soil from the head of the landslide affected area
"Soil samples were collected from the sampling sites and genomic DNA was extracted fromthe samples using DNeasy PowerSoil Kit (Qiagen, 12888), following the manufacturersprocedure. The sample purity was estimated using Nanodrop 2000 (Thermo scientific, USA)and Qubit (Thermo scientific, USA) for the absorbance ratio A260/A280 and A260/230 andquantity of DNA. The DNA libraries was constructed for the bacterial 16s rRNA using theuniversal primers Forward (341F: CCTACGGGNGGCWGCAG) and reverse (805R:GACTACHVGGGTATCTAATCC) (Klindworth et al., 2013). The amplified regions wereestimated using TapeStation D1000 ScreenTape (Agilent Technologies, Waldbonn,Germany). The sequencing was done at Macrogen facility (Seoul, Republic of Korea) usingillumina Miseq (Illumina, San Diego, CA, USA) platform based upon the manufacturesprotocol."
