From: Cleansing effect of acidic L-arginine on human oral biofilm
Comparative microbiota analysis of sustained and washed-out fractions with acidic L-arginine. Fragile (from #4) and solid biofilms (#5) were formed on plastic discs, which were then washed with saline (S), 10Â mM citrate buffer pH3.5 (CA), or acidic L-arginine (LA). The microbial composition of the fraction remaining on the discs and the washed-out fraction were compared by Illumina-based 16S rDNA sequencing analysis
