Live and heat-killed Lactobacillus spp. interfere with Streptococcus mutans and Streptococcus oralis during biofilm development on titanium surface

Biofilms represent the predominant phenotype of nearly all bacteria in their natural habitat, whether pathogenic or environmental. The biofilm formation requires a phase of adhesion to the surface where bacteria can be held for the presence of attractive forces. These are initially represented by weak reversible physical-chemical interactions, such as Van Der Walls forces, hydrophobic interactions, electrostatic interactions and hydrogen bonds, and subsequently by strong irreversible specific stereo-chemical interactions, involving binding between macromolecules of the bacterial surfaces and complementary structures (Bos, van der Mei,& Busscher, 1999).
