Abstract:
The present invention relates to a protein and/or a nucleic acid encoding such a protein that is responsible for providing tomato with a lack of fruit smoky flavour phenotype. Also part of the invention are methods for marker-assisted breeding tomato plants either having or lacking the gene or allele encoding for said protein, thereby providing respectively the absence or the presence of the smoky flavour phenotype.
Abstract:
The present invention relates to a method for determining the quality of plant material by irradiating said plant material with a beam consisting of several consecutive light pulses of electromagnetic radiation comprising one or more such wavelengths, that at least a part of the chlorophyll present is excitated by at least a part of the radiation, and for each light pulse measuring the fluorescence radiation originating from the plant material and associated with the chlorophyll transition with an imaging detector for obtaining the chlorophyll fluorescence images. The invention also relates to calculating characteristic chlorophyll fluorescence images from the chlorophyll fluorescence images that contain information about the quantum efficiency and the time response of the photosynthetic activity of the photosynthetic system of the plant material. The invention further relates to a device for recording and processing the chlorophyll fluorescence images and to methods and devices for sorting and separating plant material.
Abstract:
The invention relates to a process for the combined production of butanol and hydrogen from biomass, comprising the steps of fermenting biomass to obtain butanol in a first reaction mixture; removing the butanol and hydrogen from the first reaction mixture to obtain effluent; and using the effluent as a substrate in a second reaction mixture in a process using low substrate concentrations, in particular a hydrogen production process. Preferably, the process using low substrate concentrations is a hydrogen production process and at least part of the end products of the hydrogen production process is removed from the second reaction mixture for obtaining an effluent that comprises organic acid, which effluent is returned to the first reaction mixture.
Abstract:

Abstract:
A process for the precipitation of one or more amino and/or organic acids from a liquid feed comprising a plurality of amino and/or organic acids, comprising providing, in a precipitation vessel, a solution of amino and/or organic acids from the feed in a mixture of a solvent and an anti-solvent; passing the mixture through a zone capable of selectively removing solvent and/or adding anti-solvent from an external source to the mixture, to provide a mixture depleted in solvent and enriched in anti-solvent, thereby increasing the concentration of the amino and/or organic acids in the solvent/anti-solvent mixture, allowing solid particles of the amino and/or organic acids to precipitate from the solvent/anti-solvent mixture in the precipitation vessel at a precipitation temperature; and discharging precipitated solid particles of the amino and/or organic acids from the precipitation vessel.
Abstract:
Disclosed is the oxidation of uronic acids, such as galacturonic acid, to the corresponding aldaric acids, such as galactaric acid, under neutral or acidic conditions. Use is made of a supported gold catalyst. The oxidation occurs in good selectivity and yield, under unexpectedly mild conditions. A source of galacturonic acids is pectins, such as from sugar beet pulp.
Abstract:
A method for determining the vase life or storage history of one or more cut flowers, wherein the method comprises assaying a test sample obtained from the one or more cut flowers for one or more of: (a) an indicator representative of xylose concentration; (b) an indicator representative of β-xylosidase expression; and (c) an indicator representative of β-xylosidase activity; to determine a value for (each of) the one or more indicators in the test sample.
Abstract:
The invention relates to an elongate membrane assembly having a length, a width and a height, the assembly comprising a microporous membrane layer supported on a liquid-impermeable support layer and the assembly being suitable for lateral flow of a liquid through the membrane layer under the action of capillary forces, wherein the assembly has a constant height and at least part of the membrane layer has a first thickness in the range of from 20 to 80 µm over the entire width of the assembly. The invention further relates to a lateral flow immunoassay device comprising such membrane assembly.
Abstract:
Plasticized, unpigmented and pigmented PVC films are described which utilize a biobased, phthalate ester alternative primary plasticizer. The films show comparable color performance to the phthalate ester-plasticized unpigmented or pigmented PVC films, even where the neat biobased plasticizer has a much higher Pt-Co color as measured according to DIN-6271 (ASTM D 1209) compared to the neat phthalate ester plasticizer. Biobased primary plasticizers in the form of diesters of furan-2,5-dicarboxylic acid are especially contemplated, and provide increased thermal stability to the PVC films as an added benefit.
