New Enzymes for production of aldehydes – Enzymatic alkene cleavage

The University offers an unprecedented enzyme that cleaves alkenes to the corresponding aldehydes at the expense of molecular oxygen. This mild and selective oxidation method has broad applicability either for the preparation of aldehyde intermediated or for the chemical production of aromatic essences and flavourings enabling a reduction of chemical solvents and cheaper production processes. The markets for using this enzyme are the fine chemicals and the aromatic/flavourings industries.

Overlap Fix – High performance textile structures for composites through open reed weaving

Inventors of the RWTH Aachen University filed a patent relating the production of the multiaxial enforcement fabrics for textile composites with ORW (Open Reed Weave). To avoid load path interruptions in composites with textile enforcement, an overlapping of two yarn systems in the textile, by means of a special weaving pattern, leads to continuous load path in bias direction, reaching a “Triaxial” fabric, which is the main approach of the investigation. The Angle of additional reinforcement direction is adjustable and the calculated necessary overlapping is 16.28 mm length.
The system´s capability was verified by conducting three-point bending tests. These are performed varying the overlapping length, testing carbon and glass fibers and using reference samples as follows: [0/90°] fabrics and [0/90/45°] fabrics with continuous reinforcement. The results were successful in all cases. PROvendis offers licenses for interested enterprises on behalf of the University of Aachen.

Humanisierter anti-CCR2 Antikörper zur Therapy von MS und RA

Wissenschaftler der Universität Göttingen und der Universität Regensburg haben gemeinsamhaben gemeinsam einen anti-CCR2 Antikörper zur Therapie von Multiplen Sklerose (MS) und Rheumatoider Arthritis (RA) entwickelt. Der Spitzenantikörper wurde in Kollaboration mit dem MRC Technologies humanisiert. Er bindet CCR2 Rezeptoren und moduliert die Immunantwort durch die Depletierung von CCR2+ Monozyten.

MagnetWeft – Magnetic Weft Insertion in weaving machines

The object of the invention was hence to develop a weaving method of weft insertion that combines the advantages of the common methods whilst avoiding their deficits. This will be achieved with a magnetic projectile which is used for the guided transport of the yarn. The projectile is moved through the open shed by magnets, which are mounted on a belt. The belt is located outside of the shed. Multiple projectiles can be used simultaneously to ensure a high efficiency of the weft insertion.
The magnetic weft insertion represents an energy-efficient alternative to the standard weft insertion methods. The fact that production velocities of yarns with challenging processing characteristics can be similar to the ones of standard yarns is certainly an advantage. In magnetic weft insertion no source of compressed air is necessary, a reduction of energy consumption of about 60 % compared to a conventional air jet weaving machine is to be achieved.

Biotechnological [S,S]-EDDS Production

The complexing agent ethylenediamine-disuccinate (EDDS) is an ethylenediamine-tetraacetate (EDTA) isomer. EDTA is widely used in paper, textile, and laundry industry but also as cosmetic, food, and medical additive. Due to its poor degradability, EDTA became an environmental hazard. EDDS has similar complex-forming properties as EDTA. In contrast to EDTA, the isomer [S,S]-EDDS is biode-gradable. Therefore, a chemical process to produce [S,S]-EDDS had already been established. Howev-er, the chemical synthesis is not only expensive but also complicated.
A biotechnological large scale production of [S,S]-EDDS was not possible until now, because already 2 μM zinc, a concentration occurring ubiquitously in standard media, inhibits the synthesis of [S,S]-EDDS. Here we present a process to synthesize [S,S]-EDDS biotechnologically using an optimized Amycolatopsis japonicum strain, that produces [S,S]-EDDS in the presence of zinc and in complex media (see Figure 1).
