Abstract: Strains of Zymomonas were engineered by introducing a chimeric xylose isomerase gene that contains a mutant promoter of the Z. mobilis glyceraldehyde-3-phosphate dehydrogenase gene. The promoter directs increased expression of xylose isomerase, and when the strain is in addition engineered for expression of xylulokinase, transaldolase and transketolase, improved utilization of xylose is obtained.

Abstract: An optical sensor for detecting a substance includes a first waveguide and a second waveguide optically coupled via a directional coupler to the first waveguide. The sensor has a functional surface in a region of the directional coupler for accumulating or storing the substance to be detected so that an intensity of a coupling arranged by the directional coupler between the first waveguide and the second waveguide can be changed by the accumulating or storing of this substance. The first waveguide extends in a freely floating manner over a coupling path covered by the directional coupler or rests on a swellable material. The first waveguide is guided in a vicinity of the coupling path so that a spacing between the first waveguide and the second waveguide can be changed there by a deformation or movement of the first waveguide or of a carrier of the first waveguide.

Abstract: A hardware device for analyzing an audio signal comprises a calculator for calculating a neural activity pattern over time resulting at nerve fibers of an ear model based on the audio signal and a processor for processing the neural activity pattern to obtain a sequence of time information as an analysis representation describing a temporal position of consecutive trajectories, wherein a trajectory includes activity impulses on different nerve fibers based on the same event in the audio signal. A two-dimensional representation of the neural activity pattern is gradually distorted over time, and it is recognized when an approximately straight line is contained in the distorted two-dimensional representation of the neural activity pattern over time. Accordingly, a time information belonging to the trajectory is provided.
