Blue LED inhibits the growth of <i>Porphyromonas gingivalis</i> by suppressing the expression of genes associated with DNA replication and cell division

Abstract

The inhibition of the growth of P. gingivalis by blue LED may therefore be induced not by a bactericidal effect, but instead due to a bacteriostatic effect mediated by the suppression of the genes associated with chromosomal DNA replication and cell division at the transcriptional level.
