Abstract: The invention relates to a method for preparing a polyester polymer material, which comprises preparing a reaction medium comprising a mixture of at least one monomer chosen from ?-hydroxylated fatty acids and ?-hydroxylated fatty acid esters of an alcohol comprising an aliphatic chain comprising from 1 to 18 carbon atoms, and at least one phenolic compound, the total content of phenolic compound(s) being within a range of values from 0.3 to 42 mg equivalent of gallic acid per gram of the mixture. The method then comprises heating this reaction medium in order to carry out the polymerisation of the monomer and the phenolic compound and the cross-linking of the polymer thus formed.

Abstract: A method for preparing a polymer of the elastomer type based on a monomer selected from polyhydroxylated fatty acids and esters of a polyhydroxylated fatty acid and a C1-C18 aliphatic chain alcohol is disclosed. This method includes preparing a reaction medium by bringing the monomer with a polyol, this reaction medium being catalyst free, then a step of heating the reaction medium in order to implement the copolymerisation of the monomer and of the polyol and the cross-linking of the polymer thus formed, with at least the initial phase of this heating step being implemented at a reduced pressure.

Abstract: The invention relates to an isolated plant GDSL-lipase polypeptide differentially expressed between the different steps of the plant development and/or the different tissues of the plant, a nucleic acid molecule encoding it, and a plant or part of plant genetically engineered to not express it at least partially.

Abstract: A new method for increasing expression of a puroindoline protein in a plant, said puroindoline protein modifying grain hardness, notably breadmaking quality, said method comprising the steps of: (e) preparing a DNA construct which will allow the expression of a puroindoline protein, (f) introducing said DNA construct into plant cell, plant tissue, or plant, (g) selecting the plant cell, or plant tissue, or plant which stably maintain the puroindoline expression, (h) and optionally regenerating fertile stable transformed plant.

Abstract: The present invention is directed to a family of phospholipid binding and transporting proteins, a method for preparing same from fungi, and their use in cosmeticology, the agri-foodstuffs industry and pharmacology Phospholipid proteins are capable of binding, transporting and/or rearranging lipids between membranes, optionally in combination with active principles. Furthermore, the phospholipid proteins are hydrophobic and acidic, have a molecular weight of under 50 kDa, and may be prepared from a non-toxic filamentous fungus capable of developing on a lipid-enriched medium, particularly from raw extracts of fungi.
