1. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans
Abstract : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. READ MORE

2. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26
Abstract : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. READ MORE

3. Tailoring the course of postprandial glycaemia to bread : On the importance of viscous dietary fibre for acute and semi-acute glucose tolerance and appetite
Abstract : The prevalence of metabolic diseases such as type 2 diabetes mellitus (T2DM) is rapidly increasing all over the world. Frequent episodes of elevated postprandial blood glucose have been associated with oxidative stress and subclinical inflammation, and the importance of a tight glycaemic control has been identified as an important factor to maintain health and prevent T2DM, obesity and cardiovascular disease (CVD).

4. Enzymatic conversion of β-mannans through transglycosylation and hydrolysis : Synthesis of building blocks for novel biomaterials from renewables
Abstract : The major softwood hemicellulose is galactoglucomannan (GGM), an abundant polysaccharide which constitutes up to 25% of the dry weight of wood, much of which is discarded in current refinery practices. Among the enzymes responsible for the degradation of this hemicellulose are the β-mannanases. READ MORE

5. Enzymatic conversion of β-mannans: Analysing, evaluating and modifying transglycosylation properties of glycoside hydrolases
Abstract : Retaining glycoside hydrolases are enzymes that catalyse the breakdown down of glycans through hydrolysis. Due to the double-replacement mechanism of the retaining glycoside hydrolases (GHs), which form an intermediate with part of the glycan covalently attached to the enzyme, some GHs are able to catalyse synthesis reactions called transglycosylation.
