Abstract:

The lactic acid producing microorganisms in the oral cavity comprise a large group of species belonging to the genera Lactobacillus, Lactococcus, Streptococcus, Leuconostoc, Enterococcus and Weissella. The role of lactic acid bacteria in prevention of common oral diseases has been recently addressed. Such species establishes themselves in oral biofilms and reducing the number of oral pathogens. In this study, lactic acid bacteria isolates were isolated from biofim samples which were taken from childrens mouth. A total of 48 isolates were obtained. Isolates were stocked in 20% glycerol and then in vitro biofilm capacity of the isolates was examined by microtiter plate assay. For this purpose; glucose, fructose, sucrose, lactose, maltose, galactose were used in medium at 4% ratio. Isolates were showed different biofilm forming capacity on different carbonhydrates.
