Biochemical characterization of a recombinant Lactobacillus acidophilus strain expressing exogenous FomA protein

Our study demonstrated that, in addition to an increased adhesion ability, the recombinant L. acidophilus strain maintained the basic characteristics of the standard strain ATCC 4356, including antibiotic sensitivity. Thus, the recombinant strains have great potential to be utilized as a safe and effective periodontitis vaccine in the future.
