Abstract: A rhamnolipid composition including 30% by weight to 70% by weight, of at least one rhamnolipid and 30% by weight to 70% by weight of water, where the percentages by weight refer to the total composition, wherein the pH of the composition at 25° C. is from 5.5 to 7.0. In addition to the foregoing rhamnolipid composition, also set forth is a method to make a solution of rhamnolipids; and salt of at least one rhamnolipid.

Abstract: The invention relates to a method for cultivation of the nitrile-hydratase-producing strain Rhodococcus rhodochrous M33, using a culture medium which is based on a 12 to 60 mM phosphate buffer, covers the demand of the cells for phosphorus and maintains the pH in the range of 5.5 to 9.0 during cultivation, and to which acetic acid is added in doses as the new source of carbon after consumption of the initially supplied quantity of glucose. The invention also relates to the culture medium used in the method.

Abstract: An electric cooking appliance has a sheet steel, glass, ceramic or glass ceramic carrier plate (15), to whose underside are applied for electrical heating purposes thick film resistors (16). It can be constructed as a large-area plate with several cooking points, or as an individual hotplate, which is received in a mounting rim (26). Temperature limitation and regulation sensors (22) are applied in the form of film resistance sensors to the underside of the carrier plate.

Abstract: In an electric heating unit (1), at least one heating circuit of a heating resistor (2) is arranged as a coated or printed conductor track and is consequently arranged by means of an adhesive joint (16) on a support (3) made from a high temperature-resistant synthetic paper. The unit is fixed, on its bare side remote from the heating resistor and by means of a whole-surface adhesive joint (13), directly to the associated reception side (11) of the body (10) to be heated. The adhesive joint (13) is appropriately formed by an adhesive layer (14) of silicone resin adhesive or the like, or a self-adhesive layer with a thickness of a few tenths of a millimeter and which permanently in stress-compensating manner has roughly the same thermal stability as the support (3). At least one heating circuit can be switched by means of a mechanical temperature switch with high switching hysteresis.

Abstract: An electrical component (11) comprises a support (12) largely made from unalloyed steel sheet (13) with an aluminum coating (14). This serves as the anchoring coating for a glass, fused or fired insulating layer (15) applied to the conductor (16). The component is suitable as a self-supporting, heat-emitting room heating resistance element, as well as an electronic support and slide-in element.
