1
Increased needs for
world production :
+ 70% in 2050
Source: FAO
Cereals : + 1 billion tons
Meat : + 200 millions tons
90% of the target has to be achieved by yield improvement &
intensification.
What does this challenge mean?
Need of efficient soils with good fertility.
Need of healthy plants, with high productivity.
Need of safe feedstuffs, with good nutritional values.
Need of healthy animals, with high production potential.
The Challenge for tomorrow’s agriculture
2
10% « only » of the target can be achieved by surface increase.
Very diverse group of organisms
How can seaweeds contribute to address
this challenge?
3
Under-utilized resource
Unexplored activities
Very diverse chemical compositions
Earth is 71% covered by Ocean.
4
• Carbohydrates (20-70% of dry weight)
Sulfated polysaccharides
Alginates, fucoidans (Brown algae)
Carraghenans and agars (Red algae)
Ulvans (Green algae)
Insoluble carbohydrates
• Proteins (1-35% of dry weight)
• Lipids (0,5-4% of dry weight)
• Minerals (10-30% of dry weight)
Iron, Iodine, Cupper, Potassium, Sodium, Calcium,
Sulfate, Magnesium, Phosphorous, Chlorine, Manganese
Numerous trace-elements.
• Pigments
Phycobiliproteins (Red algae)
Carotenoids

Polysaccharides
MSP
Hétero-polysaccharide
ramifié sulfaté
1° - Diversity of the sugar units
(ex: glucose,galactose, xylose, ….)
2° - Presence of rare sugars
(ex : rhamnose, fucose)
3° - Ramification Incresed biological activities
4° - Sulfatation Unique biological activities
S
The structural similarity of Marine Sulfated
Polysaccharides to polysaccharides present in the
animal kingdom allow the seaweed polysaccharides to
display unique biological activities effective on animals

Biological activities already demonstrated for ulvan,
fucoidans and carraghenans 1,2,3:
• Antiviral
• Anti-inflammatory
• Immune modulating
• Antioxidant
• Wound healing
• Antitumoral
