1. Novel Technologies to assess Gut Health Claims for Carbohydrates Subthema: Microbiota Naam trekker: Hauke Smidt Affiliatie: Wageningen Universiteit Contactgegevens: hauke.smidt@wur.nl

2. Key aims Characterize microbial networks responsible for fibre fermentation Track place & products of fermentation Identify carbohydrates that stimulate specific populations and products (e.g. butyrate producers) Effect of carbohydrates on microbial determinants of functionality (e.g. surface decoration) Personalized ingredients - Differences between individuals/enterotypes?

3. Key technologies needed HTP functional microbiomics approaches for whole microbiota & key populations Stable isotope-based identification of fermentative microbial networks HTP in vitro screening capacity Carbohydrate metabolite profiling in intestinal samples

4. Which microbes are there? What are the microbes doing? What is the genetic potential?
