THE BIOTRANSFORMATION OF BILE ACIDS BY A COMMON MEMBER OF THE BISON GUT MICROBIOME
Bacterial biotransformation of bile acids (BAs) is increasingly recognized to play an important role in the health and disease of the host. Bile acid-modifying bacteria participate in the production of a large number of secondary BAs (2 BAs) with known and yet to be discovered activities. In the …

The impact of bile and anaerobic stress on Listeria monocytogenes isolates
… barrier. In this study the effect of bile and anaerobic stress on L. monocytogenes was assessed. Bile has antimicrobial properties and it is one of the stressors that L. monocytogenes must overcome in the human gastrointestinal tract to establish infection. L. monocytogenes uses an …

Studies of Sulfur Reduction of Taurine and Taurine-Conjugated Bile Acids by Bile acid 7α-Dehydroxylating Bacteria
Bile acids are C24 steroids that are derived in the liver from cholesterol and secreted into the intestinal lumen to aid in emulsification of dietary lipids and lipid-soluble vitamins. The indigenous intestinal microflora modify bile acids, producing up to 20 unique bile acid metabolites. The …

The microbiota and colon cancer risk: cause or consequence?
… pathways; in particular changes in free bile acids formed by the enzyme bile salt hydrolase (bsh), which is widespread in the microbiota. Results: We observed pro-tumorigenic changes in the microbial composition of our model of sporadic CRC prior to detection of host neoplastic …

The role of poi as a naturally fermented Hawaiian food in the modulation of gut health
… enterica serotype Typhimurium, as well as bile salt hydrolase activities and cholesterol assimilation. The adhesion abilities to human intestinal epithelial cells (Caco-2) varied among the LAB isolates. Furthermore, extracts from both fresh and fermented poi were tested on Caco-2 cells to …

Exploring milk management strategies for improved food safety and health outcomes in the neonate
… isolates, including exopolysaccharide activity, bile salt hydrolase activity and GABA production. In particular, four bacterial isolates were identified as putative bacteriocin producers following a series of well diffusion assays. Whole genome sequencing and predictive analysis confirmed the …

In-Vivo and In-Vitro Cholesterol Removal by Lactobacilli and Bifidobacteria
… Bifidobacterium were studied for their acid and bile tolerance. Possible mechanisms of cholesterol removal were also examined. All strains showed varying levels of tolerance at pH 2.0 for two hours. L. acidophilus ATCC 4962, L. casei ASCC 290, L. casei ASCC 292, B. longum BB536 and B. infantis …

Exploitation of probiotic strains with targeting cholesterol reduction for the formulation of functional foods [Sviluppo di ceppi probiotici con capacità di riduzione del colesterolo per la formulazione di alimenti funzionali]
… di una singola copia del gene bsh, riconducibile al loro potenziale BSH. Tra i due, VB4 ha mostrato una maggiore resistenza in presenza dei BAs e una più elevata capacità di deconiugazione. L. brevis M3R3, isolato da lievito madre, possiede due distinti geni bsh potenzialmente coinvolti …
