Bromo and Mt. Raung in East Java, Indonesia, in 2015 perturbed volcanic materials and affected surface-layer air quality at surrounding locations. During the episodes, the volcanic ash from the eruptions influenced visibility, traffic accidents, flight schedules, and human health. In this research, the volcanic ash particles were collected and characterized by relying on the detail of physical observation. We performed an assessment of the volcanic ash elements to characterize the volcanic ash using two different methods which are aqua regia extracts followed by MP-AES and XRF laboratory test of bulk samples. The analysis results showed that the volcanic ash was mixed of many materials, such as Al, Si, P, K, Ca, Ti, V, Cr, Mn, Fe, Ni, and others. Fe, Si, Ca, and Al were found as the major elements, while the others were the trace elements Ba, Cr, Cu, Mn, P, Mn, Ni, Zn, Sb, Sr, and V with the minor concentrations. XRF analyses showed that Fe dominated the elements of the volcanic ash. The XRF analysis showed that Fe was at 35.40\% in Bromo and 43.00\% in Raung of the detected elements in bulk material. The results of aqua regia extracts analyzed by MP-AES were 1.80\% and 1.70\% of Fe element for Bromo and Raung volcanoes, respectively.}, language = {en} } @article{BiselliRechmannFriedrichetal.2007, author = {Biselli, Manfred and Rechmann, Hanrik and Friedrich, Andrea and Forouzan, Dara}, title = {Characterization of photosynthetically active duckweed ( Wolffia australiana ) in vitro culture by Respiration Activity Monitoring System (RAMOS) / Henrik Rechmann, Andrea Friedrich, Dara Forouzan, Stefan Barth, Heide Schnabl, Manfred Biselli und Robert B}, series = {Biotechnology Letters. 29 (2007), H. 6}, journal = {Biotechnology Letters. 29 (2007), H. 6}, isbn = {0141-5492}, pages = {971 -- 977}, year = {2007}, language = {en} } @article{JossekBongaertsSprenger2001, author = {Jossek, Ralf and Bongaerts, Johannes and Sprenger, Georg A.}, title = {Characterization of a new feedback-resistant 3-deoxy-D-arabinoheptulosonate 7-phosphate synthase AroF of Escherichia coli}, series = {FEMS microbiology letters}, volume = {Vol. 202}, journal = {FEMS microbiology letters}, number = {Iss. 1}, issn = {1574-6968}, pages = {145 -- 148}, year = {2001}, language = {en} } @article{SelmerKimDarleyetal.2006, author = {Selmer, Thorsten and Kim, Jihoe and Darley, Daniel and Buckel, Wolfgang}, title = {Characterization of (R)-2-hydroxyisocaproate dehydrogenase and a family III coenzyme A transferase involved in reduction of L-leucine to isocaproate by Clostridium difficile / Kim, J. ; Darley, D. ; Selmer, T. ; Buckel, W.}, series = {Applied and Environmental Microbiology. 72 (2006), H. 9}, journal = {Applied and Environmental Microbiology. 72 (2006), H. 9}, isbn = {0099-2240}, pages = {6062 -- 6069}, year = {2006}, language = {en} } @inproceedings{RothMoehringTippkoetter2016, author = {Roth, J. and M{\"o}hring, S. and Tippk{\"o}tter, Nils}, title = {Characterization and evaluation of lignocellulosic biomass 130 hydrolysates for ABE fermentation}, series = {New frontiers of biotech-processes (Himmelfahrtstagung) : 02-04 May 2016, Rhein-Mosel-Halle, Koblenz/Germany}, booktitle = {New frontiers of biotech-processes (Himmelfahrtstagung) : 02-04 May 2016, Rhein-Mosel-Halle, Koblenz/Germany}, publisher = {DECHEMA}, address = {Frankfurt am Main}, pages = {130}, year = {2016}, language = {en} } @article{Lassonczyk1990, author = {Lassonczyk, Beate}, title = {Characteristics of a fossil soil developed on the basement complex in the northeast Somalia}, series = {Berliner geowissenschaftliche Abhandlungen / Reihe A, Geologie und Pal{\"a}ontologie / hrsg. von d.

Based on exoproteome analysis, B. pumilus strain Jo2, possessing a high secretion capability, was chosen for an omics-based investigation. The proteome and metabolome of B. pumilus cells growing either in minimal or complex medium was analyzed. In total, 1542 proteins were identified in growing B. pumilus cells, among them 1182 cytosolic proteins, 297 membrane and lipoproteins and 63 secreted proteins. This accounts for about 43\% of the 3616 proteins encoded in the B. pumilus Jo2 genome sequence. By using GC-MS, IP-LC/MS and H NMR methods numerous metabolites were analyzed and assigned to reconstructed metabolic pathways. In the genome sequence a functional secretion system including the components of the Sec- and Tat-secretion machinery was found. Analysis of the exoproteome revealed secretion of about 70 proteins with predicted secretion signals.

Attempts to efficiently express the enzyme in common expression hosts had failed. This study reports on the realization of overexpression in Escherichia coli after structural modification of HP70. Modelling of HP70 resulted in a two-domain structure, comprising the catalytic domain and a C-terminal domain which includes about 100 amino acids. On the basis of the modelled structure the enzyme was truncated by deletion of most of the C-terminal domain yielding HP70-C477. This structural modification allowed effective expression of active enzyme using E. coli BL21-Gold as the host. Specific activity of HP70-C477 determined with suc-l-Ala-l-Ala-l-Pro-l-Phe-p-nitroanilide as the substrate was 30 ± 5 U/mg compared to 8 ± 1 U/mg of the native enzyme. HP70-C477 was most active at 40 °C and pH 7-11; these conditions are prerequisite for a potential application as detergent enzyme. Determination of kinetic parameters at 40 °C and pH = 9.5 resulted in KM = 0.23 ± 0.01 mM and kcat = 167.5 ± 3.6 s⁻¹. MS-analysis of peptide fragments obtained from incubation of HP70 and HP70-C477 with insulin B indicated that the C-terminal domain influences the cleavage preferences of the enzyme.

Here we present a method using 1H spectra of benchtop as well as conventional NMR systems in combination with multivariate data analysis, to determine lignin's molecular weight (Mw and Mn) and polydispersity index (PDI). A set of 36 organosolv lignin samples (from Miscanthus x giganteus, Paulownia tomentosa and Silphium perfoliatum) was used for the calibration and cross validation, and 17 samples were used as external validation set. Validation errors between 5.6\% and 12.9\% were achieved for all parameters on all NMR devices (43, 60, 500 and 600 MHz). Surprisingly, no significant difference in the performance of the benchtop and high-field devices was found. This facilitates the application of this method for determining lignin's molecular weight in an industrial environment because of the low maintenance expenditure, small footprint, ruggedness, and low cost of permanent magnet benchtop NMR systems.}, language = {en} } @article{BiselliThoemmesKulaetal.1994, author = {Biselli, Manfred and Th{\"o}mmes, J. and Kula, M.-R. and Wandrey, Christian}, title = {Batch kinetic data of hybridoma growth and productivity as a basis for the simulation of antibody production in various culture systems / Th{\"o}mmes, J. ; Biselli, M. ; Kula, M.-R. ; Wandrey, C.}, series = {Animal cell technology : products of today, prospects for tomorrow ; ESACT, European Society for Animal Cell Technology, the 12th meeting / Ed.

In this study the response of B. pumilus to oxidative stress was investigated during a treatment with high concentrations of hydrogen peroxide at the proteome, transcriptome and metabolome level. Genes/proteins belonging to regulons, which are known to have important functions in the oxidative stress response of other organisms, were found to be upregulated, such as the Fur, Spx, SOS or CtsR regulon. Strikingly, parts of the fundamental PerR regulon responding to peroxide stress in B. subtilis are not encoded in the B. pumilus genome. Thus, B. pumilus misses the catalase KatA, the DNA-protection protein MrgA or the alkyl hydroperoxide reductase AhpCF. Data of this study suggests that the catalase KatX2 takes over the function of the missing KatA in the oxidative stress response of B. pumilus. The genome-wide expression analysis revealed an induction of bacillithiol (Cys-GlcN-malate, BSH) relevant genes. An analysis of the intracellular metabolites detected high intracellular levels of this protective metabolite, which indicates the importance of bacillithiol in the peroxide stress resistance of B. pumilus.}, language = {en} } @article{BiselliVanderPolDeGooijeretal.1996, author = {Biselli, Manfred and Van der Pol, Jens J. and De Gooijer, Cornelis D. and Wandrey, Christian}, title = {Automation of selective assays for on-line bioprocess monitoring by flow-injection analysis / van der Pol, Jens J. ; de Gooijer, Cornelis D. ; Biselli, Manfred ; Wandrey, Christian ; Tramper, Johannes}, series = {Trends in Biotechnology. 14 (1996), H. 12}, journal = {Trends in Biotechnology. 14 (1996), H. 12}, isbn = {0167-7799}, pages = {471 -- 477}, year = {1996}, language = {en} } @article{ReugelsBoggettiScheeretal.2006, author = {Reugels, Alexander M. and Boggetti, Barbara and Scheer, Nico and Campos-Ortega, Jos{\´e} A.}, title = {Asymmetric localization of Numb:EGFP in dividing neuroepithelial cells during neurulation in Danio rerio}, series = {Developmental Dynamics}, volume = {235}, journal = {Developmental Dynamics}, number = {4}, issn = {1097-0177}, doi = {10.1002/dvdy.20699}, pages = {934 -- 948}, year = {2006}, language = {en} } @article{InfantinoPaulssenMostaccietal.2016, author = {Infantino, Angelo and Paulßen, Elisabeth and Mostacci, Domiziano and Schaffer, Paul and Trinczek, Michael and Hoehr, Cornelia}, title = {Assessment of the production of medical isotopes using the Monte Carlo code FLUKA: Simulations against experimental measurements}, series = {Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms}, volume = {366}, journal = {Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1872-9584}, doi = {10.1016/j.nimb.2015.10.067}, pages = {117 -- 123}, year = {2016}, abstract = {The Monte Carlo code FLUKA is used to simulate the production of a number of positron emitting radionuclides, ¹⁸F, ¹³N, ⁹⁴Tc, ⁴⁴Sc, ⁶⁸Ga, ⁸⁶Y, ⁸⁹Zr, ⁵²Mn, ⁶¹Cu and ⁵⁵Co, on a small medical cyclotron with a proton beam energy of 13 MeV.

In conventional lab-on-a-chip-platforms, solvents and samples are passed through defined microfluidic channels with complex flow control installations. The droplet actuation platform presented here is a promising alternative. With it, it is possible to move a liquid drop (microreactor) on a planar surface of a reaction platform (lab-in-a-drop). The actuation of microreactors on the hydrophobic surface of the platform is based on the use of magnetic forces acting on the outer shell of the liquid drops which is made of a thin layer of superhydrophobic magnetite particles. The hydrophobic surface of the platform is needed to avoid any contact between the liquid core and the surface to allow a smooth movement of the microreactor. On the platform, one or more microreactors with volumes of 10 µL can be positioned and moved simultaneously. The platform itself consists of a 3 x 3 matrix of electrical double coils which accommodate either neodymium or iron cores. The magnetic field gradients are automatically controlled. By variation of the magnetic field gradients, the microreactors' magnetic hydrophobic shell can be manipulated automatically to move the microreactor or open the shell reversibly. Reactions of substrates and corresponding enzymes can be initiated by merging the microreactors or bringing them into contact with surface immobilized catalysts.}, language = {en} } @article{OjovanSteinmetz2022, author = {Ojovan, Michael I. and Steinmetz, Hans-J{\"u}rgen}, title = {Approaches to Disposal of Nuclear Waste}, series = {Energies}, volume = {15}, journal = {Energies}, number = {20}, publisher = {MDPI}, address = {Basel}, issn = {1996-1073}, doi = {10.3390/en15207804}, pages = {Artikel 7804}, year = {2022}, abstract = {We present a concise mini overview on the approaches to the disposal of nuclear waste currently used or deployed. The disposal of nuclear waste is the end point of nuclear waste management (NWM) activities and is the emplacement of waste in an appropriate facility without the intention to retrieve it. The IAEA has developed an internationally accepted classification scheme based on the end points of NWM, which is used as guidance. Retention times needed for safe isolation of waste radionuclides are estimated based on the radiotoxicity of nuclear waste. Disposal facilities usually rely on a multi-barrier defence system to isolate the waste from the biosphere, which comprises the natural geological barrier and the engineered barrier system. Disposal facilities could be of a trench type, vaults, tunnels, shafts, boreholes, or mined repositories. A graded approach relates the depth of the disposal facilities' location with the level of hazard.

When different radionuclides are present simultaneously, additional processing is needed to distinguish distributions of radionuclides.

By subtracting images pixel-by-pixel one can generate images representing certain ranges of β-particle energies. The method is applied to the measurement of irradiated reactor graphite samples containing several radionuclides to determine the spatial distribution of these radionuclides within pre-defined energy windows. The process was repeated under fixed parameters after thermal treatment of the samples. The greyscale images of the distribution after treatment were subtracted from the corresponding pre-treatment images. Significant changes in the intensity and distribution of radionuclides could be observed in some samples. Due to the thermal treatment parameters the most significant differences were observed in the ³H and ¹⁴C inventory and distribution.}, language = {en} }
