Drmamad Posted April 1, 2017 Posted April 1, 2017 I have citrus sinensis 's peel extract. I wanna to test this on mouth's microorganisms. Does this test, works???
Country Boy Posted April 1, 2017 Posted April 1, 2017 Does what test work? You say you want to do a test but don't say what test!
Drmamad Posted April 2, 2017 Author Posted April 2, 2017 Yes. Sorry. I want to test orange's peel extract on streptococcus mutans. If this test works, i will create a toothpaste with that extract. My question is,"does orange's peel extract good for dental and mouth?" Help me. I got orange's peel extract by soxhelt! I got orange's peel extract by soxhelt!
StringJunky Posted April 2, 2017 Posted April 2, 2017 Limonene is probably the active ingredient and it does seem to have inhibitory activity against streptococcus species. Abstract The present study explores the efficacy of limonene, a cyclic terpene found in the rind of citrus fruits, for antibiofilm potential against species of the genus Streptococcus, which have been deeply studied worldwide owing to their multiple pathogenic efficacy. Limonene showed a concentration-dependent reduction in the biofilm formation of Streptococcus pyogenes (SF370), with minimal biofilm inhibitory concentration (MBIC) of 400 μg ml - 1. Limonene was found to possess about 75-95 % antibiofilm activity against all the pathogens tested, viz. Streptococcus pyogenes (SF370 and 5 clinical isolates), Streptococcus mutans (UA159) and Streptococcus mitis (ATCC 6249) at 400 μg ml - 1 concentration. Microscopic analysis of biofilm architecture revealed a quantitative breach in biofilm formation. Results of a surface-coating assay suggested that the possible mode of action of limonene could be by inhibiting bacterial adhesion to surfaces, thereby preventing the biofilm formation cascade. Susceptibility of limonene-treated Streptococcus pyogenes to healthy human blood goes in unison with gene expression studies in which the mga gene was found to be downregulated. Anti-cariogenic efficacy of limonene against Streptococcus mutans was confirmed, with inhibition of acid production and downregulation of the vicR gene. Downregulation of the covR, mga and vicR genes, which play a critical role in regulating surface-associated proteins in Streptococcus pyogenes and Streptococcus mutans, respectively, is yet further evidence to show that limonene targets surface-associated proteins. The results of physiological assays and gene expression studies clearly show that the surface-associated antagonistic mechanism of limonene also reduces surface-mediated virulence factors. https://www.ncbi.nlm.nih.gov/pubmed/26294065 1
