the resistance to bile salt of the strains might be induced by potential presence of some proteins
found that different bilte tolerance levels of 3 Lb.plantarum strains were correlated to six proteins
that may be important to the bile salt response and adaptation in Lb.plantarum.
in our experiments,after all of the isolates were treated with simulated gastric juices for 3 h,they were incubated under bile salt conditions.
most of experiments studying acid and bile salt torerance have been individually performed.the survival of LAB in the gastro-intestinal tract is affected by whether these two
