Bioactive molecules from marine plants biomasses

Pré-requis nécessaires

Basic marine biology, marine biochemistry, botany.

Compétences visées

Learning outcomes for students are to obtain a comprehensive vision, in a context of sustainable and innovative researches:

- of the macroalgal and halophytes industries at different scales (France, Europe and worldwide)
- on the possibilities to valorize marine plants
- on the application of biotechnological processes in the domain of marine sciences

- on biological assays which could be carried out along the research of innovative marine ingredients  

- on the formulation of ingredients.

Students will also acquire:

- the ability to transpose data/concepts of the scientific literature into R & D approaches integrating scaling-up.
- the capacity to bind extractive and purification processes and their uses, depending on the needs of industrials

Descriptif

Introduction: utilization of marine plants worldwide, chemodiversity and sectors which use marine plants

Chapter 1: Global overview of the marine plants industry in France, Europe and in the world: definitions, types of resources (harvested, cultivated resources together with beaching), markets, value chains, culture versus harvesting following countries with case studies in occidental and oriental countries (for seaweeds).

Chapter 2: The different industrial sectors which use marine plants: general properties, specificities of marine ingredients, classical and innovative uses

Chapter 3: focus on phenolic compounds: extraction, purification, quantification and biological activities, innovative and green processes for their extraction/purification, applications in cosmetic, agrifood and medical industries

Chapter 4: focus on carbohydrates (mono-, di- and polysaccharides): extraction, purification, quantification and biological activities, innovative and green processes for their extraction/purification, applications in cosmetic and medical industries

Chapter 5: focus on marine lipids (terpens, fatty acids,…): extraction, purification, quantification and biological activities, applications in fouling industries and use as natural conservatives.

Chapter 6: innovations in relation with researches on marine plants. Cosmetic Ingredients and formulation: theory and practical way to obtain a cosmetic product.
