Molecular Mechanisms of , LGG Probiotic Function.

To advance probiotic research, a comprehensive understanding of bacterial interactions with human physiology at the molecular and cellular levels is fundamental. LGG is a bacterial strain that has long been recognized for its beneficial effects on human health. Probiotic effector molecules derived from LGG, including secreted proteins, surface-anchored proteins, polysaccharides, and lipoteichoic acids, which interact with host physiological processes have been identified.

Bifidobacterium adolescentis - a beneficial microbe.

Bifidobacterium adolescentis is one of the most abundant bifidobacterial species in the human large intestine, and is prevalent in 60-80% of healthy human adults with cell densities ranging from 109-1010 cells/g of faeces. Lower abundance is found in children and in elderly individuals. The species is evolutionary adapted to fermenting plant-derived glycans and is equipped with an extensive sugar transporter and degradation enzymes repertoire.

Characterization of the Vaginal DNA Virome in Health and Dysbiosis.

Bacterial vaginosis (BV) is characterized by a reduction in spp. abundance and increased abundance of facultative anaerobes, such as spp. BV aetiology is not fully understood; however, bacteriophages could play a pivotal role in the perturbation of the vaginal bacterial community.

Effect of potato fiber on survival of Lactobacillus species at simulated gastric conditions and composition of the gut microbiota in vitro.

Potato fiber is a side product in starch manufacturing rich in dietary fibers such as pectin, cellulose, hemicellulose and resistant starch. So far, the beneficial properties of potato fiber have been poorly characterized. This study investigated the effect of FiberBind 400, a commercial potato fiber product, on survival of probiotic Lactobacillus strains at simulated gastric conditions and on the composition and metabolic activity of the gut microbiota, using the TIM-2 colon model.

Four weeks supplementation with Lactobacillus paracasei subsp. paracasei L. casei W8® shows modest effect on triacylglycerol in young healthy adults.

The microbiota has been shown to have the potential to affect appetite and blood lipids positively in animal studies. We investigated if four weeks supplementation with Lactobacillus paracasei subsp. paracasei L.
