Abstract: Brewing unit of a beverage preparation machine with a brewing chamber (10) and a brewing chamber surface (15), wherein the brewing chamber (10) is designed to be substantially rotationally symmetrical with respect to an axis (16) directed from a first brewing chamber half (11) to a second brewing chamber half (12). The brewing chamber (10) has a maximum axial extension (17) in the direction of the axis (16), which is smaller than the largest diameter (18) transverse to the axis (16). Furthermore, the brewing chamber (10) has a thickness (19) in the area of the axis (16) which is equal to or smaller than the axial expansion (17).

Abstract: Brewing unit (3) for a beverage preparation machine with a first brewing chamber half (11) and a second brewing chamber half (12), which are arranged to be movable relative to one another from a closed position for forming a closed brewing chamber into an open position in which a capsule (60) can be inserted into the brewing chamber. The brewing unit (3) has at least one, preferably two, holding means (38) which hold a capsule (60) in an intermediate position in the open position between the first and second brewing chamber halves (11, 12) when the capsule (60) is inserted and release it when the brewing chamber is closed. Before release by the holding means (38), the first and second brewing chamber halves (11, 12) are spaced apart in such a way that the brewing chamber halves (11, 12) cannot grip a capsule (60).

Abstract: A beverage preparation device (1), in particular a coffee machine, with a housing (2), an outlet (5) for discharging a beverage into a beverage container and a support element (6) for supporting the beverage container, said support element being arranged in a detachable manner in the insert openings (9, 10) which are arranged on the front side of the housing (4) and which are at variable distances to the outlet (5). The insertion openings (9, 10) are associated with closure means (12) for closing the insertion openings (9, 10) when the support device (6) is not inserted.

Abstract: A guitar is provided which has a guitar neck. At least the fretboard of the neck is made of a high-density bamboo, that is, a compressed grass, instead of a wood. The guitar may be an electric guitar. In an alternative, the entire neck can also be made of high-density bamboo. The high-density bamboo is planed from compressed raw strips horizontally or vertically glued together and pressed to form high-density bamboo, known as HDG bamboo or strand woven bamboo. The frets on the fretboard are inserted into milled grooves in the fretboard in the usual manner. The curvature between the guitar neck and the guitar head can be produced by bending a single-piece wooden workpiece after steaming so that the wood fibres running along the guitar neck run continuously into the guitar head.

Abstract: The present invention relates to the use of nucleic acid molecules coding for a bacterial xylose isomerase (XI), preferably coming from Clostridium phytofermentans, for reaction/metabolization, particularly fermentation, of recombinant microorganisms of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol, by means of xylose fermenting yeasts. The present invention further relates to cells, particularly eukaryotic cells, which are transformed utilizing a nucleic acid expression construct which codes for a xylose isomerase, wherein the expression of the nucleic acid expression construct imparts to the cells the capability to directly isomerize xylose into xylulose. Said cells are preferably utilized for reaction/metabolization, particularly fermentation, of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol.

Abstract: The method for pasteurisation and/or sterilisation of a food according to the invention comprises, in a first step, provision of a device (1) for the impingement of steam, particularly water vapour, on a food. The food is then impinged upon with steam for the pasteurisation and/or sterilisation of the food by means of the steam in order to achieve a reduction in the quantity of a microorganism present on and/or in the food, particularly a pathogenic microorganism. Before the food is impinged upon with steam, the temperature of the food is brought to a preheating temperature greater than or equal to the pasteurisation and/or sterilisation temperature.

Abstract: A device for processing roasted coffee beans, including a unit for grinding the beans, and a method for processing coffee beans, wherein the coffee beans are ground and the temperature of the coffee to be ground, at least at the start of the grinding operation, is between 30° C. and 150° C., in particular between 35° C. and 100° C., preferably between 40° C. and 90° C., and more preferably between 40° C. and 60° C. For this purpose, the device includes a thermal unit.

Abstract: The present invention relates to a polypeptide which has a novel specific arabinose transporter function as well as to nucleic acids coding therefore. The invention further relates to host cells, in particular modified yeast strains which contain the coding nucleic acids and express the polypeptide and functionally integrate it into the plasma membrane and are thus able to absorb L-arabinose. When using modified host cells which express additional proteins of the arabinose metabolic pathway, arabinose can be fermented by these cells, in particular into ethanol. The present invention is therefore relevant, inter alia, in connection with the production of biochemicals from biomass, such as bioethanol for example.
