Abstract: Presented herein are genetically engineered Pseudomonas strains capable of metabolizing ethylene glycol and producing polyhydroxyalkanoates.

Abstract: The invention relates to an improved encoding disk for an optical rotation angle sensor or a rotary encoder, an optical rotation sensor or rotary encoder comprising an improved encoding disk, and a method for optically correcting or compensating for an angle measuring error of a rotary encoder, in particular an angle measuring error which is contingent on a displacement or decentralization of the encoding disk. The encoding disk (20) comprises at least one measuring track (22) and at least one compensating track (24), wherein the measuring track (22) is in a first radial region of the encoding disk (20); and the compensating track (24) is centered with regard to the measuring track (22) on a second radial region of the encoding disk (20) so that the center of the measuring track (22) coincides with the center of the compensating track (24).

Abstract: An apparatus for separation or synthesis of process substances is configured with at least two cell stacks, within each of which there is arranged at least one large-area layer for the separation or synthesis and passages are formed for feeding and discharging at least one process substance to or from the at least one layer. To ensure that the ratio of active surface area to total area of the layer is as high as possible yet on the other hand that uniform distribution of at least one process substance over the layer are ensured, at least two passages for a process substance are formed within at least a first cell stack, of which a first passage is used to pass the process substance through the first cell stack to a second cell stack and of which the second passage is used to feed or discharge the process substance to or from the at least one layer in the first cell stack.

Abstract: A whole cell catalyst is described comprising a hydantoinase, a racemase and a carbamoylase. Thus this catalyst is able to degrade hydantoins directly into the amino acids. Additionally, a process for the production of this catalysts and for the production of amino acids is claimed.

Abstract: A microorganism is described which is transformed with DNAs which encode a hydantoinnase, a racemase, and a carbamoylase. As a result, the microorganism is able to degrade hydantoins directly to amino acids. A process for the production of the microorganism and a process for producing amino acids with the microorganism is also described.
