BIBS

BIBS: BIORESSOURCES : IMAGERIE, BIOCHIMIE & STRUCTURE  (Cf. Rapport Recherche et Innovation TRANSFORM 2022)

▶️ The BIBS platform is one of the four constituent platforms of the PROBE research infrastructure, which is itself a component of the Food axis of CALIS. This platform is located at the INRAE Pays de la Loire Center (Nantes site). It is attached to the research unit Biopolymers Interactions Assemblies (BIA) of the INRAE TRANSFORM scientific department. The BIA UR develops the main scientific thematic objectives of improving the quality and functionality of native agro-resources, developing new healthy and sustainable processed foods, and designing composite bio-based materials.

▶️ BIBS is dedicated to the structural characterization of biopolymers (polysaccharides, lipids, proteins), in biological systems (plants, plant organs, cells…) or synthetic and model systems (foods and food matrices). This platform brings together expertise in different analytical domains and data processing, allowing to describe, according to different modalities and on a range of scales from millimeter to nanometer, the structures and architectures of agro-sourced systems. The techniques developed allow to study the biopolymers that compose them (polysaccharides, proteins, lipids) and to:

• characterize the structure of biopolymers (identification, quantification, modifications), their interactions, their organization (local orders, mobility), their localization
• follow their degradation or transformation screen collections of samples on chemical and structural criteria
• image the systems by different modalities and at different scales, to realize correlative imaging
• address dynamic parameters (diffusion)

▶️ The BIBS platform is recognized as a Collective Scientific Infrastructure INRAE (ISC), and labeled by the GIS IBISA. Its activities are certified ISO9001 (version 2015).
