Analysis of S-layer proteins of Lactobacillus brevis.
The presence of S-layer proteins in Lactobacillus brevis was examined by SDS-PAGE analysis. Thirty six out of a total of 41 L. brevis strains possessed S-layer proteins of molecular masses ranging from 38 to 55 kDa. Western blot analysis using antisera raised against whole cells of S-layer protein-carrying strains demonstrated the heterogeneity of L. brevis S-layer proteins. No clear relationship was observed between the presence of S-layer proteins or their immunological characteristics and the physiological activity of L. brevis as a beer spoilage organism.
