| Research Abstract |
Our aim was to construct a new screening method for highly adhesive lactobacilli based on an enzymatic activity without using the adhesion test. Thirty lactobacilli isolates from human intestinal tissues were measured for cell surface GAPDH activity. GAPDH activities were detected in all samples from 18 h cultures. This suggests GAPDH is universally expressed on the bacterial cell surfaces from many lactobacilli. Thenew screening method using GAPDH enzymatic activity without an adhesion test may be possible due to the positive correlation of GAPDH activity with adhesion of lactobacilli.Moreover, the heat shock protein, GroEL, was also detected in many lactobacilli. This suggests GAPDH and GroEL are a very important protein not only in the cytoplasm but also on the cell surface and may be a universal adhesin for lactobacilli.
