Patent ID: 8506953

Claim:
An isolated microorganism of the genus Lactobacillus capable of reducing peptide concentration in saliva, wherein the isolated microorganism is obtained by: (a) culturing a microorganism of the genus Lactobacillus for 24 h at 37° C. under anaerobic conditions in a synthetic medium containing a starting peptide concentration of 15 g/l of the medium with a starting cell density of 1×10 7 cells/ml to obtain a cell culture; (b) centrifuging the cell culture at 4000×g for 15 min to obtain a supernatant; and (c) determining the peptide concentration of the supernatant and comparing with the starting peptide concentration of the synthetic medium to identify a microorganism which reduces the starting peptide concentration of the synthetic medium by at least 20% after 24 h of incubation.
