Evaluation of an Adapted Semi-Automated DNA Extraction for Human Salivary Shotgun Metagenomics

In this study, we proposed a semi-automated DNA extraction protocol for human salivary samples collected with a commercial kit, and compared the outcomes with the DNA extraction recommended by the manufacturer. This study demonstrates that our semi-automated protocol is suitable for shotgun metagenomic analysis, by significantly producing higher DNA fragment sizes, while allowing for improved sample treatment logistics with reduced technical variability and without compromising the structure of the oral microbiome.
