As a proof of principle, the existing NMR routine for the analysis of Aloe vera products was modified. Instead of using absolute integrals of targeted compounds and internal standard (nicotinamide) from 1H-NMR spectra, quantification was performed based on the ratio of a particular 1H-NMR compound integral and 2H-NMR signal of deuterated solvent D2O. Validation characteristics (linearity, repeatability, accuracy) were evaluated and the results showed that the method has the same precision as internal standardization in case of multicomponent screening. Moreover, a dehydration process by freeze drying is not necessary for the new routine. Now, our NMR profiling of A. vera products needs only limited sample preparation and data processing. The new standardization methodology provides an appealing alternative for multicomponent NMR screening. In general, this novel approach, using standardization by 2H integral, benefits from reduced sample preparation steps and uncertainties, and is recommended in different application areas (purity determination, forensics, pharmaceutical analysis, etc.).}, language = {en} } @article{KotterHoffmann2002, author = {Kotter, Michael and Hoffmann, U.}, title = {Simulation eines geregelten R{\"u}hrkessels mit LABVIEW / U.

Both in its varied natural habitats and in industrial settings, B. licheniformis cells will be exposed to increases in the external osmolarity, conditions that trigger water efflux, impair turgor, cause the cessation of growth, and negatively affect the productivity of cell factories in biotechnological processes. We have taken here both systems-wide and targeted physiological approaches to unravel the core of the osmostress responses of B. licheniformis. Cells were suddenly subjected to an osmotic upshift of considerable magnitude (with 1 M NaCl), and their transcriptional profile was then recorded in a time-resolved fashion on a genome-wide scale. A bioinformatics cluster analysis was used to group the osmotically up-regulated genes into categories that are functionally associated with the synthesis and import of osmostress-relieving compounds (compatible solutes), the SigB-controlled general stress response, and genes whose functional annotation suggests that salt stress triggers secondary oxidative stress responses in B. licheniformis. The data set focusing on the transcriptional profile of B. licheniformis was enriched by proteomics aimed at identifying those proteins that were accumulated by the cells through increased biosynthesis in response to osmotic stress. Furthermore, these global approaches were augmented by a set of experiments that addressed the synthesis of the compatible solutes proline and glycine betaine and assessed the growth-enhancing effects of various osmoprotectants. Combined, our data provide a blueprint of the cellular adjustment processes of B. licheniformis to both sudden and sustained osmotic stress.}, language = {en} } @article{MartinsBlaserFeliksetal.2011, author = {Martins, Berta M. and Blaser, Martin and Feliks, Mikolaj and Ullmann, Matthias G. and Buckel, Wolfgang and Selmer, Thorsten}, title = {Structural basis for a Kolbe-type decarboxylation catalyzed by a glycyl radical enzyme}, series = {Journal of the American Chemical Society}, journal = {Journal of the American Chemical Society}, publisher = {ACS Publications}, address = {Washington, DC}, pages = {1 -- 33}, year = {2011}, language = {en} } @article{KotterLintzRiekertetal.1989, author = {Kotter, Michael and Lintz, Hans-G{\"u}nther and Riekert, Lothar and Trimm, D.

Additionally, they provide interesting model systems to study polymers under nanoconfinement due to the well-defined layered nanocomposite arrangement. Although the general behavior in terms of forming such layered nanocomposite materials using evaporative self-assembly and controlling the nanoclay gallery spacing by the nanoclay/polymer ratio is understood, some combinations of polymer matrices and nanoclay reinforcement do not comply with the established models. Here, we demonstrate a thorough characterization and analysis of such an unusual polymer/nanoclay pair that falls outside of the general behavior. Poly(ethylene oxide) (PEO) and sodium fluorohectorite form nacre-mimetic, lamellar nanocomposites that are completely transparent and show high mechanical stiffness and high gas barrier, but there is only limited expansion of the nanoclay gallery spacing when adding increasing amounts of polymer. This behavior is maintained for molecular weights of PEO varied over four orders of magnitude and can be traced back to depletion forces. By careful investigation via X-ray diffraction and proton low-resolution solid-state NMR, we are able to quantify the amount of mobile and immobilized polymer species in between the nanoclay galleries and around proposed tactoid stacks embedded in a PEO matrix.

In particular, screening and optimization runs with acceptable amounts of expensive and hardly available catalysts, reagents, or biomolecules are feasible with microfluidic technologies. The presented new microfluidic system is based on the inclusion of small liquid volumes by a protective shell of magnetizable microparticles. Hereby, discrete aqueous microreactor drops with volumes of 1-30 μL can be formed on a simple planar surface. A digital movement and manipulation of the microreactor is performed by overlapping magnetic forces. The magnetic forces are generated by an electrical coil matrix positioned below a glass plate. With the new platform technology, several discrete reaction compartments can be moved simultaneously on one surface. Due to the magnetic fields, the reactors can even be merged to initiate reactions by mixing or positioned above surface-immobilized catalysts and then opened by magnetic force. Comparative synthesis routes of the magnetizable shell particles and superhydrophobic glass slides including their performance and stability with the reaction platform are described. The influence of diffusive mass transport during the catalyzed reaction is discussed by evaluation finite element model of the microreactor.

This problem is getting worse and even continues in temperate climatic regions due to climate change. To address this problem, the use of biodegradable hydrogels is increasingly important for the application as water-retaining additives in soil. Furthermore, efficient (micro-)nutrient supply can be provided by the use of tailored hydrogels. Biodegradable polyaspartic acid (PASP) hydrogels with different available (1,6-hexamethylene diamine (HMD) and L-lysine (LYS)) and newly developed crosslinkers based on diesters of glycine (GLY) and (di-)ethylene glycol (DEG and EG, respectively) were synthesized and characterized using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) and regarding their swelling properties (kinetic, absorbency under load (AUL)) as well as biodegradability of PASP hydrogel. Copper (II) and zinc (II), respectively, were loaded as micronutrients in two different approaches: in situ with crosslinking and subsequent loading of prepared hydrogels. The results showed successful syntheses of di-glycine-ester-based crosslinkers. Hydrogels with good water-absorbing properties were formed. Moreover, the developed crosslinking agents in combination with the specific reaction conditions resulted in higher water absorbency with increased crosslinker content used in synthesis (10\% vs. 20\%). The prepared hydrogels are candidates for water-storing soil additives due to the biodegradability of PASP, which is shown in an exemple. The incorporation of Cu(II) and Zn(II) ions can provide these micronutrients for plant growth.}, language = {en} } @article{TurckBerndt1981, author = {Turck, Christoph W. and Berndt, Heinz}, title = {Synthese definierter Peptid-Derivate durch Aminolyse von 3-(Nα-Acyl-peptidyloxy)-2-hydroxy-N-alkylbenzamiden bei erh{\"o}hten Temperaturen, I : Synthese des Modellpeptid-Derivates Z-Ala-Phe-Gly-N(Et)2}, series = {Hoppe-Seyler´s Zeitschrift f{\"u}r physiologische Chemie}, volume = {362}, journal = {Hoppe-Seyler´s Zeitschrift f{\"u}r physiologische Chemie}, number = {1}, issn = {1437-4315}, doi = {10.1515/bchm2.1981.362.1.821}, pages = {821 -- 828}, year = {1981}, language = {de} } @article{WolfBerndtBrandenburg1979, author = {Wolf, G{\"u}nter and Berndt, Heinz and Brandenburg, Dietrich}, title = {Synthese der [LysA13] Rinderinsulin-A-Kette in der Form [Lys(Tfa)A13]A(SO3H)4 und NαA1-Msc-[LysA13]A(SO3H)4 unter Verwendung des S-tert-Butylmercapto-Restes als Thiolschutzgruppe}, series = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, volume = {360}, journal = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, number = {2}, issn = {1437-4315}, doi = {10.1515/bchm2.1979.360.2.1569}, pages = {1569 -- 1578}, year = {1979}, language = {de} } @article{GielenWolfBerndtetal.1979, author = {Gielen, Hans-G{\"u}nther and Wolf, G{\"u}nter and Berndt, Heinz and Zahn, Helmut}, title = {Synthese der Fragmente A1-8, A9-15 und A16-21 der Schafinsulin-A-Kette unter Verwendung des S-tert-Butylmercaptorestes als Thiolschutzgruppe}, series = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, volume = {360}, journal = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, number = {2}, issn = {1437-4315}, doi = {10.1515/bchm2.1979.360.2.1535}, pages = {1535 -- 1548}, year = {1979}, language = {de} } @article{Berndt1979, author = {Berndt, Heinz}, title = {Synthese der Sequenz 71—86 des Humanproinsulins, I : Synthese der Sequenz 71—86 als monomeres cyclisches Biscystinpeptidderivat und als Tetra-S-tritylderivat}, series = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, volume = {360}, journal = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, number = {1}, issn = {1437-4315}, doi = {10.1515/bchm2.1979.360.1.747}, pages = {747 -- 760}, year = {1979}, language = {de} } @article{Berndt1979, author = {Berndt, Heinz}, title = {Synthese der Sequenz 71—86 des Humanproinsulins, III : Synthese {\"u}ber die Fragmente 71—78 und 79—86}, series = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, volume = {360}, journal = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, number = {1}, issn = {1437-4315}, doi = {10.1515/bchm2.1979.360.1.765}, pages = {765 -- 772}, year = {1979}, language = {de} } @article{WolfBerndtBrandenburg1979, author = {Wolf, Wilhelm and Berndt, Heinz and Brandenburg, Dietrich}, title = {Synthese von Fragmenten einer [LysA13] Rinder-Insulin-A-Kette unter Verwendung des S-tert-Butylmercaptorestes als Thiolschutz}, series = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, volume = {360}, journal = {Hoppe-Seyler's Zeitschrift f{\"u}r physiologische Chemie}, number = {2}, issn = {1437-4315}, doi = {10.1515/bchm2.1979.360.2.1549}, pages = {1549 -- 1558}, year = {1979}, language = {de} } @article{MeyerStorkHoeckerBerndt1992, author = {Meyer-Stork, L.
