MiSeq of wood metagenome
Wood chips were crushed in liquid nitrogen using a sterile mortar and pestle. Approximatively 100-150 mg of wood were then used for DNA extraction using the FastDNA Spin Kit for Soil (MP Biomedicals). DNA concentrations were measured by fluorescence with a Quant-iT PicoGreen dsDNA Assay Kit (ThermoFisher Scientific, Waltham, Massachusetts, USA) using a Tecan Spark  (Tecan Group Ltd., Mannedorf, Switzerland), and normalized to 1 ng.L-1 using before PCR amplification. 479F (5 CAGCMGCYGCNGTAANAC 3) and R888 (5 CCGYCAATTCMTTTRAGT 3) primers were used to amplify the V3-V4 regions of the 16S rRNA gene (Terrat et al., 2015).
