As a proof of principle, the existing NMR procedure for the analysis of heparin products according to US Pharmacopeia monograph is extended to the determination of Na+ and Cl- content in this matrix. Quantification is performed based on the ratio of a 23Na (35Cl) NMR integral and 2H NMR signal of deuterated solvent, D2O, acquired using the specific spectrometer hardware. As an alternative, the possibility of 133Cs standardization using the addition of Cs2CO3 stock solution is shown. Validation characteristics (linearity, repeatability, sensitivity) are evaluated. A holistic NMR profiling of heparin products can now also be used for the quantitative determination of inorganic compounds in a single analytical run using a single sample. In general, the new standardization methodology provides an appealing alternative for the NMR screening of inorganic and organic components in pharmaceutical products.}, language = {en} } @article{PrielmeierLang1988, author = {Prielmeier, Franz and Lang, E.

In our approach, we progressively equilibrate the melt structure above the tube scale, inside the tube and finally at the monomeric scale. We make use of models designed to be computationally effective at each scale. Density fluctuations in the melt structure above the tube scale are minimized through a Monte Carlo simulated annealing of a lattice polymer model. Subsequently the melt structure below the tube scale is equilibrated via the Rouse dynamics of a force-capped Kremer-Grest model that allows chains to partially interpenetrate. Finally the Kremer-Grest force field is introduced to freeze the topological state and enforce correct monomer packing. We generate 15 melts of 500 chains of 10.000 beads for varying chain stiffness as well as a number of melts with 1.000 chains of 15.000 monomers. To validate the equilibration process we study the time evolution of bulk, collective, and single-chain observables at the monomeric, mesoscopic, and macroscopic length scales. Extension of the present method to longer, branched, or polydisperse chains, and/or larger system sizes is straightforward.}, language = {en} } @article{BaumannGronsfeldSchuetzLembach1997, author = {Baumann, Marcus and Gronsfeld, A. and Sch{\"u}tz-Lembach, G.}, title = {Nachdenklichkeit {\"u}ber Nachhaltigkeit : wie uns ein neues Wort alte Probleme neu entdecken l{\"a}ßt}, series = {Wechselwirkung : Wissenschaft \& vernetztes Denken}, volume = {19}, journal = {Wechselwirkung : Wissenschaft \& vernetztes Denken}, number = {87}, issn = {0172-1623}, pages = {6 -- 11}, year = {1997}, language = {de} } @book{Selmer1996, author = {Selmer, Thorsten}, title = {Nachweis einer neuartigen posttranslationalen Modifikation in Sulfatasen und ihr Fehlen in Enzymen aus Patienten mit multipler Sulfatase-Defizienz}, publisher = {Cuvillier}, address = {G{\"o}ttingen}, pages = {XIII, 143, IX S. : graph.

Monitoring cleaning properties of exhaust air cleaning systems and to detect small but significant changes in emission characteristics during a fattening cycle is important for both emission and fattening process control. In the present study, we evaluated the potential of near-infrared spectroscopy (NIRS) combined with chemometric techniques as a monitoring tool of exhaust air from poultry operation systems. To generate a high-quality data set for evaluation, the exhaust air of two poultry houses was sampled by applying state-of-the-art filter sampling protocols. The two stables were identical except for one crucial difference, the presence or absence of an exhaust air cleaning system. In total, twenty-one exhaust air samples were collected at the two sites to monitor spectral differences caused by the cleaning device, and to follow changes in exhaust air characteristics during a fattening period. The total dust load was analyzed by gravimetric determination and included as a response variable in multivariate data analysis. The filter samples were directly measured with NIR spectroscopy. Principal component analysis (PCA), linear discriminant analysis (LDA), and factor analysis (FA) were effective in classifying the NIR exhaust air spectra according to fattening day and origin. The results indicate that the dust load and the composition of exhaust air (inorganic or organic matter) substantially influence the NIR spectral patterns. In conclusion, NIR spectroscopy as a tool is a promising and very rapid way to detect differences between exhaust air samples based on still not clearly defined circumstances triggered during a fattening period and the availability of an exhaust air cleaning system.}, language = {en} } @misc{SiegertWielandEngelskirchenetal.2008, author = {Siegert, Petra and Wieland, Susanne and Engelskirchen, Julia and Merkel, Marion and Maurer, Karl-Heinz and Bessler, Cornelius}, title = {Neue Alkalische Protease aus Bacillus gibsonii und Wasch- und Reinigungsmittel enthaltend diese neue Alkalische Protease [Offenlegungsschrift]}, publisher = {Deutsches Patentamt / Europ{\"a}isches Patentamt / WIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 51}, year = {2008}, language = {de} } @misc{MerkelWeberSiegertetal.2006, author = {Merkel, Marion and Weber, Angrit and Siegert, Petra and Wieland, Susanne and Maurer, Karl-Heinz and Bessler, Cornelius}, title = {Neue Alkalische Protease aus Bacillus gibsonii und Wasch- und Reinigungsmittel enthaltend diese neue Alkalische Protease [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / WIPO}, address = {M{\"u}nchen / Genf}, pages = {1 -- 46}, year = {2006}, language = {de} } @article{BiselliJelinekSchmidtetal.2001, author = {Biselli, Manfred and Jelinek, N. and Schmidt, S. and Hilbert, U.}, title = {Neue Bioreaktoren zur Kultivierung h{\"a}matopoetischer Zellen / Jelinek, N. ; Schmidt, S. ; Hilbert, U. ; Thoma, S. ; Biselli, M. ; Wandrey, C.}, series = {Chemie Ingenieur Technik. 73 (2001), H. 7}, journal = {Chemie Ingenieur Technik. 73 (2001), H. 7}, isbn = {0009-286X}, pages = {894 -- 898}, year = {2001}, language = {de} } @book{Berndt2014, author = {Berndt, Heinz}, title = {Neue Kondensations-Methoden zur Synthese definierter Peptid-Derivate}, address = {Aachen}, pages = {XII, VI, 207 S. : graph.

Apart from the pretreatment of the raw material, hydrolysis is the basis for the conversion of the cellulose and hemicellulose fraction into fermentable sugars. After hydrolysis, usually a solid-liquid separation takes place, in order to separate the residual plant material from the sugar-rich fraction, which can be subsequently used in a fermentation step. In order to factor out the separation step, the usage of in alginate immobilized crude cellulose fiber beads (CFBs) were evaluated. Pretreated cellulose fibers are incorporated in an alginate matrix together with the relevant enzymes. In doing so, sugars diffuse trough the alginate matrix, allowing a simplified delivery into the surrounding fluid. This again reduces product inhibition of the glucose on the enzyme catalysts. By means of standardized bead production the hydrolysis in lab scale was possible. First results show that liberation of glucose and xylose is possible, allowing a maximum total sugar yield of 75 \%.}, language = {en} } @article{SelmerPierikHeider2005, author = {Selmer, Thorsten and Pierik, Antonio J. and Heider, Johann}, title = {New glycyl radical enzymes catalysing key metabolic steps in anaerobic bacteria}, series = {Biological Chemistry. 386 (2005), H. 10}, journal = {Biological Chemistry. 386 (2005), H. 10}, isbn = {1431-6730}, pages = {981 -- 988}, year = {2005}, language = {en} } @article{OehlenschlaegerVolkmarStiefelmaieretal.2024, author = {Oehlenschl{\"a}ger, Katharina and Volkmar, Marianne and Stiefelmaier, Judith and Langsdorf, Alexander and Holtmann, Dirk and Tippk{\"o}tter, Nils and Ulber, Roland}, title = {New insights into the influence of pre-culture on robust solvent production of C. acetobutylicum}, series = {Applied Microbiology and Biotechnology}, volume = {108}, journal = {Applied Microbiology and Biotechnology}, publisher = {Springer}, address = {Berlin, Heidelberg}, issn = {1432-0614}, doi = {10.1007/s00253-023-12981-8}, pages = {10 Seiten}, year = {2024}, abstract = {Clostridia are known for their solvent production, especially the production of butanol. Concerning the projected depletion of fossil fuels, this is of great interest. The cultivation of clostridia is known to be challenging, and it is difficult to achieve reproducible results and robust processes. However, existing publications usually concentrate on the cultivation conditions of the main culture. In this paper, the influence of cryo-conservation and pre-culture on growth and solvent production in the resulting main cultivation are examined. A protocol was developed that leads to reproducible cultivations of Clostridium acetobutylicum. Detailed investigation of the cell conservation in cryo-cultures ensured reliable cell growth in the pre-culture. Moreover, a reason for the acid crash in the main culture was found, based on the cultivation conditions of the pre-culture. The critical parameter to avoid the acid crash and accomplish the shift to the solventogenesis of clostridia is the metabolic phase in which the cells of the pre-culture were at the time of inoculation of the main culture; this depends on the cultivation time of the pre-culture. Using cells from the exponential growth phase to inoculate the main culture leads to an acid crash. To achieve the solventogenic phase with butanol production, the inoculum should consist of older cells which are in the stationary growth phase. Considering these parameters, which affect the entire cultivation process, reproducible results and reliable solvent production are ensured.}, language = {en} }
