The mechanism underlying antimicrobial activity of conjugated bile acids against strains of
lactic acid bacilli is not well understood. The purpose of this study was to investigate two …

This study was designed to evaluate the effects of bile acid deconjugation by probiotic
strains on the antibiotic susceptibility of antibiotic-sensitive and multiple antibiotic-resistant …

Bile salts are potent antimicrobial agents and are an important component of innate
defenses in the intestine, giving protection against invasive organisms. They play an …

The effect of the conjugated bile acid (BA) on the microbial internal pH (pHin) values in lactic
acid bacteria with and without ability to hydrolyze bile salts (BSH [+] and BSH [−] strains …

Bacteria of numerous species isolated from the human gastrointestinal tract express bile salt
hydrolase (BSH) activity. How this activity contributes to functions of the microorganisms in …

Bile tolerance is an important criterion in the selection of microbial strains for probiotic use.
The survival and morphological changes of a potential probiotic strain, Lactobacillus …

Eleven strains of lactobacilli were screened for their bile salt deconjugation ability, bile salt
hydrolase activity (BSH) and co-precipitation of cholesterol with deconjugated bile. Bile salt …

The effects of bile salts on the survival of lactobacilli were investigated using glycocholic
acid, cholic acid and deoxycholic acid as model compounds and the bile salt hydrolase …

To investigate the effects of conjugated bile acid on bacterial growth and cholyglycine
hydrolase activity, Clostridium perfingens from human feces was exposed to varying …

Bacterial bile salt hydrolysis is considered a risk factor for the development of colon cancer
because of the risk of forming harmful secondary bile salts after an initial deconjugation step …
