There are many different types of oral bacteria that can convert nitrates to nitrites, and together they make up about 20% of all oral bacteria in most people.
Scientific Claim
The oral microbiome contains a diverse range of nitrate-reducing bacteria, with 20 specific species identified in this study representing approximately 20% of all measured oral taxa.
Original Statement
“Nitrate‐reducing bacterial species represented 20±16% of all measured taxa. From the list of 28 putative nitrate‐reducing oral species, 20 taxa were identified by HOMINGS.”
