Abstract: The invention relates to a method for extracting oxygen form a reaction chamber, as well as a use of microorganisms in such a method and a photobioreactor for carrying out the method. According to the invention, the method comprises the steps—irradiating at least one phototropic microorganism with light under anaerobic conditions in a reaction chamber, and—in situ bonding of produced oxygen by means of the microorganism by oxidation of an oxygen-utilizing substrates.

Abstract: What is described herein refers to isolated nucleic acid fragments encoding an oxygenase subunit (StyA) and a reductase subunit (StyB), wherein the polypeptide encoded for by the nucleotide sequence for the oxygenase subunit (StyA) and the nucleotide sequence for the reductase subunit (StyB) have activity towards chiral arylsulfides.

Abstract: A method processes a stable emulsion having components from whole-cell biotransformations such as cells, soluble cell components, organic solvents and/or water. In this connection, the emulsion, which is stable after the biotransformation, is mixed with further parts of organic phase, and subsequently the mixture is continuously stirred until a catastrophic phase inversion of the emulsion takes place while mixing; subsequently, this phase-inverted mixture is transferred to a settling container, where the phases of the emulsion separate from one another and can be separated from one another.

Abstract: The invention provides a biocatalytic process for oxidation of organic compounds with the aid of an alkL gene product, and microorganisms used in this process.

Abstract: The present invention relates to a cell, which has been genetically modified relative to its wild type, so that in comparison with its wild type it is able to produce more ?-aminocarboxylic acids, more ?-aminocarboxylic acid esters or more lactams derived from ?-aminocarboxylic acids, starting from carboxylic acids or carboxylic acid esters. Furthermore, the present invention relates to a method for the production of a genetically modified cell, the cells obtainable by this method, a method for the production of ?-aminocarboxylic acids, of ?-aminocarboxylic acid esters or of lactams derived from ?-aminocarboxylic acids, the ?-aminocarboxylic acids, ?-aminocarboxylic acid esters or lactams derived from ?-aminocarboxylic acids obtainable by this method, a method for the production of polyamides based on ?-aminocarboxylic acids or based on lactams and the polyamides obtainable by this method.

Abstract: The method separates emulsions derived from whole-cell biotransformations, including stable emulsions derived from typical biocatalytic two-phase processes that result with such a biotransformation. A supercritical extraction to obtain the valuable product can follow directly, because of the use of compressed or supercritical gas as the separation agent. It is unimportant whether the valuable product is present in the aqueous or the organic phase. Recycling of the organic phase is possible, since the surfactant cell components decisively responsible for the formation of the stable emulsion can be separated off via sedimentation, because of the treatment. The achieved separation remains in existence even after the gas has gassed out, so that aside from extraction, other methods for product isolation can also follow, if necessary.

Abstract: The method presented represents a possibility for separating emulsions derived from whole-cell biotransformations, which method makes it possible to effectively separate stable emulsions derived from typical biocatalytic two-phase processes that result in connection with such a biotransformation, by means of at least one compressed or supercritical gas. In this connection, a supercritical extraction to obtain the valuable product can follow directly, because of the use of compressed or supercritical gas as the separation agent. It is unimportant, in this connection, whether the valuable product is present in the aqueous or the organic phase. Recycling of the organic phase is possible, since the surfactant cell components, which are decisively responsible for the formation of the stable emulsion, can be separated off by means of sedimentation, because of the treatment.

Abstract: A device (10) having a first vehicle (11) and a second vehicle (13) which are connected to one another via a communication link (12). The first vehicle (11) has operational units (21), which are actuated in the typical way during driving. In the first vehicle (11), there are connections (23) for transmitting vehicle information (24) which is correlated to the actuation of the operational units (21). Switching means (28) are used for the purpose of switching over the first vehicle (11) from a driving mode into a remote operation mode. A transmitter (27) is used for converting the vehicle information (24) into signals and for transmitting the signals from the first vehicle (11) to the second vehicle (13). The second vehicle (13) includes a receiver (31) for receiving the signals and for converting them into control information.
