DNA extraction was performed with a QIAamp tissue kit (Qiagen, Basel, Switzerland) according to the manufacturers recommendations. The soil or stool samples are lysed via chemical and mechanical homogenization. Overnight cultures from isolated colonies were used for total gDNA extraction with the DNeasy Blood & Tissue kit (Qiagen), and extraction yield was quantified using a Qubit (Thermo Fisher Scientific). To overcome this, continue mixing the solution by inverting it gentlyuntil a homogeneous blue suspension is achieved. Perform all protocol steps at room temperature. Always be sure to calibrate the spectrophotometer with the same solution. RNeasy Kits ensure that the RNA is of sufficient quality. It should be stored at room temperature. The expected yield of genomic DNA isolated from bacteria with the DNeasy Blood & Tissue Kit or the QIAamp DNA Mini Kit is approximately 10 ug of DNA per 2x 10 9 bacterial cells. Please see the Appendix sections in the RNeasy handbooks for additional information.
