Twenty-seven Lactobacillus strains isolated from traditional Chinese cheese were evaluated for their probiotic potential by in vitro and in vivo tests. Seven strains were selected as they showed high resistance to low pH and simulated gastrointestinal juice. Further study indicated that five strains exhibited good adhesion to Caco-2 cells.

How soybean protein hydrolysates (SPHs) to favor the growth of S. thermophilus ST were investigated. Hydrolyzed soybean protein was fractionated to 4 fragments, that is, SPH-I, SPH-II, SPH-III, and SPH-IV according to their molecular weight sizes. SPHs can improve the growth of strain ST, in which SPH-IV, with the molecular weight of less than 5 kD,(More)
Di-n-butyl phthalate (DBP) is a ubiquitous environmental contaminant that poses a risk to humans. Previous work indicates that the ability of lactic acid bacteria (LAB) to bind phthalic acid esters is strain-specific. As cell suspensions of LAB strains in aqueous solution are likely to be colloidal dispersions, this study provided a technique to efficiently(More)
