Probiotics are good bacteria that are either the same as or very similar to the bacteria that are already in your body. Your lower digestive tract alone teems with a complex and diverse community of these bacteria. In fact, there are a greater number of bacteria in your intestines than there are cells in your body. There are discrepancies in manuscripts regarding if there is a role of lactobacilli or other probiotic bacteria in the formation or prevention of bacteria biofilm.

Many studies have reported the beneficial effect of probiotic strains in biofilm form, including increased resistance to temperature, gastric pH.
Effective use of probiotics as antimicrobial alternatives and to eradicate biofilms formed by multidrug-resistant E. coli, Vibrio, Streptococcus mutans, Staph aureus and others.

Most of studies have demonstrated that biofilm formation by Lactobacillus (LAB) is a beneficial property because it promotes colonization and a longer permanence of LAB in the mucosa of the host. Biofilm formation by LAB also impedes colonization by pathogenic bacteria through different mechanisms including immunomodulation. The development of new technologies of encapsulation to maintain the viability of probiotic and to allow them to arrive to their target site. Considering the increased bacterial viability in stressful environments, such as high temperatures and lyophilization, recent studies have focused on biofilm forming encapsulated bacteria rather than planktonic ones. Further studies on encapsulated biofilm forming strains of the genus Lactobacillus are necessary in order to determine the mechanism of action of each particular biofilm forming strain against clinically important pathogens.
