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} } @article{KruegerGroetzingerBerndt1987, author = {Kr{\"u}ger, G{\"o}tz and Gr{\"o}tzinger, Joachim and Berndt, Heinz}, title = {Enantiomeric resolution of amino acid derivatives on chiral stationary phases by high-performance liquid chromatography}, series = {Journal of Chromatography A}, volume = {1987}, journal = {Journal of Chromatography A}, number = {397}, issn = {0021-9673}, doi = {10.1016/S0021-9673(01)85005-6}, pages = {223 -- 232}, year = {1987}, language = {en} } @article{FontiEilmannGarciaGonzalezetal.2009, author = {Fonti, Patrick and Eilmann, Britta and Garc{\´i}a-Gonz{\´a}lez, Ignacio and von Arx, Georg}, title = {Expeditious building of ring-porous earlywood vessel chronologies without loosing signal information}, series = {Trees : structure and function}, volume = {23}, journal = {Trees : structure and function}, number = {3}, publisher = {Springer}, address = {Berlin}, issn = {0931-1890 (Print)}, doi = {10.1007/s00468-008-0310-z}, pages = {665 -- 671}, year = {2009}, language = {en} } @article{HerrmannLippke1999, author = {Herrmann, Ulf and Lippke, F.}, title = {The influence of transients on the design of DSG solar fields}, series = {Journal de Physique IV : proceedings}, volume = {9}, journal = {Journal de Physique IV : proceedings}, number = {PR3}, isbn = {2-86883-402-7}, issn = {1764-7177 (Online)}, doi = {10.1051/jp4:1999377}, pages = {489 -- 494}, year = {1999}, language = {en} } @article{WangAnikFrohberg1988, author = {Wang, Mao and Anik, Sabri and Frohberg, Martin G.}, title = {Experiments on the electrochemical determination of the sulphur activities in the system copper-silver at 1200°C}, series = {Zeitschrift f{\"u}r Metallkunde}, volume = {79}, journal = {Zeitschrift f{\"u}r Metallkunde}, number = {5}, issn = {0044-3093}, pages = {336 -- 339}, year = {1988}, language = {en} } @article{EilmannZweifelBuchmannetal.2011, author = {Eilmann, Britta and Zweifel, Roman and Buchmann, Nina and Graf Pannatier, Elisabeth and Rigling, Andreas}, title = {Drought alters timing, quantity, and quality of wood formation in Scots pine}, series = {Journal of Experimental Botany}, volume = {62}, journal = {Journal of Experimental Botany}, number = {8}, publisher = {Oxford University Press}, address = {Oxford}, issn = {1460-2431 (Online)}, doi = {10.1093/jxb/erq443}, pages = {2763 -- 2771}, year = {2011}, language = {en} } @article{AnikFrohbergKapoor1983, author = {Anik, Sabri and Frohberg, Martin G. and Kapoor, Madan Lal}, title = {Prediction of thermodynamic properties of oxygen in binary metallic solvents}, series = {Zeitschrift f{\"u}r Metallkunde}, volume = {74}, journal = {Zeitschrift f{\"u}r Metallkunde}, number = {6}, issn = {0044-3093}, pages = {372 -- 375}, year = {1983}, language = {en} } @article{VahidpourAlghazaliAkcaetal.2022, author = {Vahidpour, Farnoosh and Alghazali, Yousef and Akca, Sevilay and Hommes, Gregor and Sch{\"o}ning, Michael Josef}, title = {An Enzyme-Based Interdigitated Electrode-Type Biosensor for Detecting Low Concentrations of H₂O₂ Vapor/Aerosol}, series = {Chemosensors}, volume = {10}, journal = {Chemosensors}, number = {6}, publisher = {MDPI}, address = {Basel}, issn = {2227-9040}, doi = {10.3390/chemosensors10060202}, pages = {Arikel 202}, year = {2022}, abstract = {This work introduces a novel method for the detection of H₂O₂ vapor/aerosol of low concentrations, which is mainly applied in the sterilization of equipment in medical industry. Interdigitated electrode (IDE) structures have been fabricated by means of microfabrication techniques. A differential setup of IDEs was prepared, containing an active sensor element (active IDE) and a passive sensor element (passive IDE), where the former was immobilized with an enzymatic membrane of horseradish peroxidase that is selective towards H₂O₂. Changes in the IDEs' capacitance values (active sensor element versus passive sensor element) under H₂O₂ vapor/aerosol atmosphere proved the detection in the concentration range up to 630 ppm with a fast response time (<60 s). The influence of relative humidity was also tested with regard to the sensor signal, showing no cross-sensitivity. The repeatability assessment of the IDE biosensors confirmed their stable capacitive signal in eight subsequent cycles of exposure to H₂O₂ vapor/aerosol. Room-temperature detection of H₂O₂ vapor/aerosol with such miniaturized biosensors will allow a future three-dimensional, flexible mapping of aseptic chambers and help to evaluate sterilization assurance in medical industry.}, language = {en} } @article{BragardSoltauThomasetal.2010, author = {Bragard, Michael and Soltau, N. and Thomas, S. and De Doncker, R.

After a short overview, this paper focuses on two exemplary battery storage systems, including the required power electronics. The grid integration, as well as the optimal usage of volatile energy reserves, is presented for a 5- kW PV system for home application, as well as for a 100- MW medium-voltage system, intended for wind farm usage.

As a consequence, the use of wild-type animal models to predict the role of human CYP2C enzymes in drug metabolism and drug-drug interactions is limited. Within the human CYP2C cluster CYP2C9 is of particular importance, because it is one of the most abundant P450 enzymes in human liver, and it is involved in the metabolism of a wide variety of important drugs and environmental chemicals. To investigate the in vivo functions of cytochrome P450 Cyp2c genes and to establish a model for studying the functions of CYP2C9 in vivo, we have generated a mouse model with a deletion of the murine Cyp2c gene cluster and a corresponding humanized model expressing CYP2C9 specifically in the liver. Despite the high number of functional genes in the mouse Cyp2c cluster and the reported roles of some of these proteins in different biological processes, mice deleted for Cyp2c genes were viable and fertile but showed certain phenotypic alterations in the liver. The expression of CYP2C9 in the liver also resulted in viable animals active in the metabolism and disposition of a number of CYP2C9 substrates. These mouse lines provide a powerful tool for studying the role of Cyp2c genes and of CYP2C9 in particular in drug disposition and as a factor in drug-drug interaction.}, language = {en} } @article{StojnicSassKlaassenOrlovicetal.2013, author = {Stojnic, Srdjan and Sass-Klaassen, Ute G.

To understand how chronic drought affects tree growth and tree-ring δ13C values, we studied mature Scots pine in an irrigation experiment in an inner-Alpine valley. Tree growth and isotope analyses were carried out at the annual and seasonal scale. At the seasonal scale, maximum δ13C values were measured after the hottest and driest period of the year, and were associated with decreasing growth rates. Inter-annual δ13C values in early- and latewood showed a strong correlation with annual climatic conditions and an immediate decrease as a response to irrigation. This indicates a tight coupling between wood formation and the freshly produced assimilates for trees exposed to chronic drought. This rapid appearance of the isotopic signal is a strong indication for an immediate and direct transfer of newly synthesized assimilates for biomass production. The fast appearance and the distinct isotopic signal suggest a low availability of old stored carbohydrates. If this was a sign for C-storage depletion, an increasing mortality could be expected when stressors increase the need for carbohydrate for defence, repair or regeneration.}, language = {en} } @article{KalbeKuropkaMeyerStorketal.1988, author = {Kalbe, Jochen and Kuropka, Rolf and Meyer-Stork, L.
