  • Our goal is to engineer a common yogurt bacteria, Lactobacillus bulgaricus, so that it will express the 20aa peptide p1025. A clinical study (Kelly CG et al.; Nature Biotechnol. 1999) reports that p1025 is good for your teeth. p1025 reduces oral colonization of Streptococcus mutans, a tooth-decaying bacterium.
    • Stage 1: Construction of p1025 fusion peptide and expression of gene in E. coli. This is an intermediate step to evaluate gene function and protein secretion/efficacy.
    • Stage 2: Binding Assay - see if the p1025 produced by E.coli inhibits binding of S. mutants to HA beads.
    • Stage 3: Expression of p1025 in Lactobacillus.
    • Stage 4: Make yogurt with modified Lactobacillus and test for inhibition of S. mutants binding.
