A new lactic acid bacteria with gluten-degrading activity which was isolated from salted sea foods (traditional Korea fermented food), identified as Weissella confusa (99%) by use of API kit and 16S rRNA sequencing, and designated as W. confusa. When the W. confusa cultured for 48 hours at 30℃ in a MRS medium containing 1% gluten, 45% of gluten was founded to be degraded. W. confusa showed 85% of survival rate at pH 3, and 94% tolerance at 0.1% oxgall, which indicates that W. confusa would survive in stomach of human. Experiments on the thermostability was confirmed that it has a stability of 70% in 50℃. W. confusa inhibited the growth of some pathogen, except for S. aureus. Results in this study suggest that using W. confusa for fermentation of grain flour containing gluten would be desirable to prepare the gluten-free foods needed for those who suffer from celia disease and gluten allergy.
