Abstract: The invention relates to a method for extracting high-quality polyisoprene by grinding plants via rotary shearing using a device comprising at least one rotor and at least one stator, into particles of size smaller than 1 mm, or grinding at a pH higher than 3 and lower than 8. This method is implemented in aqueous phase and allows the preparation of a dispersion of polyisoprene in water having a weight average molecular weight (MW) higher than 800 000 g/mol. The polyisoprene is extracted from plants and in particular from guayule (Parthenium argentatum). It is a method that is particularly heedful of the environment.

Abstract: A biotechnology process that employs membrane technology for obtaining an extract rich in tannins of ellagic acid from blackberries (Rubus spp.) and from other fruits that contain these compounds, as well as to the extract obtained using this method. The method is essentially based on baromembrane technologies that allow mechanical separation and effective fractionation between the polyphenol compounds, by interactions between the physico-chemical properties thereof, the material of the membrane and the molar mass of same, thereby allowing enrichment of a fraction of the natural extract with ellagic acid tannins and modification of the content thereof in terms of anthocyanins and other compounds such as sugars and acids.

Abstract: The process for the dry fractionation of lignocellulosic biomass of at least 50% by weight of lignins, cellulose and hemicelluloses. The biomass is fragmented to obtain an ultrafine powder. The process includes at least one step of separating a fraction enriched with cellulose and a fraction enriched with lignin, hemicelluloses and minerals by electrostatic sorting of the ultrafine particles. Preferably, the fraction separation step includes a step of triboelectrostatic charging of ultrafine particles and at least one step of deviating a path in the electric field of the charged particles to sort the particles.

Abstract: The present invention relates to a method for extracting phenolic compounds with low molecular weights from olive fruit water; the invention also relates to compositions enriched with phenolic compounds including at least 40% of dry matter, said dry matter consisting of at least 30% hydroxytyrosol; the invention also relates to a method for drying said compositions by spraying using grape polyphenol extracts as a drying medium as well as to powders titrated with phenolic compounds of olives and grapes obtained after drying.

Abstract: The present invention relates to novel tools for detecting Xanthomonas axonopodis pv. allii, in particular the molecular detection of specific polynucleotide sequences of said strain.

Abstract: The invention relates to an antigenic structure that contains a tryptophan epitope, characterised in that said structure is made up of a tryptophan pattern W or a peptide of 3 or 4 amino acids comprising a pattern W, coupled with glutaraldehyde. The invention can he used for screening trypanosomiasis in humans or animals.

Abstract: The invention relates to interfering RNAs (siRNAs, shRNAs or pre-miRNAs) directed against conserved regions of the mRNA of the N gene encoding the morbillivirus nucleoprotein. The invention also relates to the use of said interfering RNAs for the production of medicaments for use in the treatment or prevention of a morbillivirus infection.

Abstract: The invention provides a combination of target genes that are useful as genetic markers for the strain-specific detection of Ehrlichia ruminantium. The invention also provides diagnostic methods using said combination of markers.

Abstract: The invention provides genes that are unique either to Ehrlichia ruminantium strain Gardel or to Ehrlichia ruminantium strain Welgevonden, or allelic couples which are present in both strains but whose sequences differ between the two strains, as genetic markers to differentiate between these two strains. The invention also provides diagnostic methods using these genetic markers.

Abstract: Three gene clusters that together encode albicidin biosynthesis, the complete gene DNA sequences, and the deduced protein sequences for the enzymes and methods for using the DNA sequences are disclosed and discussed as well as methods for plant protection and creating new antibiotics. The novel Albicidin family of antibiotics is disclosed and their structure deduced.

Abstract: A device for detecting defects (2, 3) in fibrous materials (4, 22) includes members (16, 17) for squeezing the material against a film (1), a separating member (24) downstream of the squeezing members for separating the fibrous material from the film, and an opto-electronic sensor (6) downstream of the separating member for imaging the film and defects. An image processing assembly (26, 44) is electrically connected to the output of the imaging assembly for sensing and counting the marks left on the film by the defects. A member (25) is provided for moving the film relative to the opto-electronic sensor. Various optical systems, particularly polarizers (9, 10), may be incorporated into the device.

Abstract: An Ananas comosus variety is provided that forms attractive orange-red oval to cylindrical fruit with relatively flat fruitlets. The fruit is substantially uniformly colored from top to bottom when ripe even in the absence of chemical treatment with a growth regulator. The fruit flesh is golden yellow and substantially homogeneous. When compared to Smooth Cayenne (non-patented in the United States), the fruit flesh in generally sweeter and commonly contains substantially more ascorbic acid. Such higher ascorbic acid content is of nutritional benefit and serves to retard the browning of the flesh. Completely spineless piping leaves are formed. On an infrequent basis peduncle slips are formed that commonly are spaced below the fruit and do not to pose any significant interference. The fruit crown is long, erect, and conical. The fruit yield is generally comparable to that of Smooth Cayenne.

Abstract: A new vanilla variety (Vanilla planifolia, vanilla orchid) designated as ‘Handa’ is provided that produces aromatic fruit having a suitable vanillin content and combines superior agronomic and technologic properties as compared to ordinary vanilla, notably resistance to Fusarium oxysporum f. sp. radicis vanillae, and indehiscence of the fruit.
