Abstract: The disclosure regards a welding robot for performing welding operations when engaged by a positioning arm; the welding robot comprising, a robot arm configured for being connected to the positioning arm at a mounting point, a welding gun connected to the robot arm, wherein an at least first remote center of motion is defined by a point on a kinematic chain along the robot arm and the positioning arm. The welding robot is configured to continuously monitor the at least first remote center of motion and a tool center point of the welding gun during operation of the welding gun.

Abstract: The present invention pertains to a composition for the manufacture of a medicament comprising living or dead bacteria with controlled amounts of surface-coupled proteins or proteinaceous compounds and a method for the preparation of the composition. The bacterium provides a multivalent heterologous protein display vehicle that may be used in the manufacture of vaccines or medicaments for delivery via the mucosa.

Abstract: The present invention concerns a new &bgr;-galactosidase with transgalactosylating activity isolated from Bifidobacterium bifidum and a truncated enzyme where the C-terminal end of the &bgr;-galactosidase protein has been deleted, resulting in an enzyme with a higher transgalactosylating activity than hydrolase activity. When lactose is used as a substrate, galacto-oligosaccharides are products of the transgalactosylase activity. Galacto-oligosaccharides enhance growth of health-promoting Bifidobacterium that may be used in a number of applications in the dairy industry.

Abstract: A novel L-arabinose isomerase active enzyme and its corresponding gene, derived from a thermophilic source are provided. The enzyme is suitable for the production of D-tagatose, a useful low-calorie sweetener. The enzyme may be obtained from a Thermoanaerobacter species such as Thermoanaerobacter mathranii.

Abstract: Tagatose is manufactured by hydrolyzing lactose to galactose and glucose and isomerizing galactose to tagatose and chromatographic separation and recycling any unconverted compounds. Thereby high yields of pure tagatose are obtained.
