Previous studies evidenced that luxS mutants developed an altered biofilm and exhibited enhanced cell-surface hydrophobicity in E. faecalis [32]. Several other studies also had a similar observation of the negative impact of luxS mutants in Streptococcus anginosus, and S. mutans biofilms [33, 34]. But still, the role of luxS dependent quorum sensing is not well established in E. faecalis biofilm."}
