Novel techniques for microencapsulation of probiotic bacteria
Microencapsulation of living cells such as probiotic bacteria can be used for the protection of the cells from harsh conditions such as low pH and mechanical stress in the digestive system. In this thesis we demonstrate various novel strategies to microencapsulate living yeast cells as a model for …

Probiotic Supplementation, The Gut Microbiota, and Cardiovascular Health
… modulating agents, such as antibiotics and probiotics, attenuate high fat feeding induced CVD in rodent models. In humans, the capacity to produce TMAO following L-carnitine or phosphatidylcholine challenges is abolished after receiving broad spectrum antibiotics for a period of one week. …

Probiotic metabolism of human milk oligosaccharides (HMOs) and prebiotics
… this study, the first aim was to investigate the probiotic metabolism of HMOs and HMO precursors. Growth parameters were determined by inoculating glucose-grown cultures into basal deMan Rogosa Sharpe (MRS) (no added glucose) with 1% carbohydrate (+0.5 g/l L- cysteine for bifidobacteria) and …

Evaluation of bacterial polymers as protective agents for sensitive probiotic bacteria
Probiotics are live microorganisms which when administered in adequate amounts confer one or more health benefits on the host. Different processing conditions, the acidic condition of the stomach and exposure to hydrolytic enzymes affect the viability and efficacy of probiotic organisms. This study …
