Functional intestinal microbiome, new frontiers in prebiotic design.

Area of Science:

• Microbiology
• Nutrition Science
• Genomics

Background:

• The Human Microbiome Project provides functional metagenomic data, transforming understanding of host-intestinal microbiota symbiosis.
• Diet, gut microbiota, and host nutrition dynamics are crucial for understanding prebiotic structure-function relationships.

Purpose of the Study:

• To revise the prebiotic concept in the context of the metagenomic era.
• To explore tailoring prebiotic formulas for specific health attributes.
• To identify novel prebiotic molecules from sourdough microbial communities.

Main Methods:

• Analysis of functional metagenomic data from the Human Microbiome Project.
• Functional genomic studies of sourdough microbial communities.
• Integration of massive sequencing of bacterial genomes and metagenomes.

Main Results:

• Metagenomic data offers deeper insights into diet-microbiota-host interactions.
• Functional genomics reveals potential for novel prebiotic molecule biosynthesis.
• Rational production of prebiotics with specific functional properties is enabled.

Conclusions:

• The metagenomic era necessitates a revised prebiotic concept.
• Tailored prebiotic formulas can be developed based on structure-function insights.
• Advanced genomic and metagenomic analyses facilitate the discovery and production of novel prebiotics.
