Metagenomic profiling pipelines improve taxonomic classification for 16S amplicon sequencing data

Scientific Reports, 2023
Most experiments studying bacterial microbiomes rely on the PCR amplification of all or part of the gene for the 16S rRNA subunit, which serves as a biomarker for identifying and quantifying the various taxa present in a microbiome sample.
