Characterisation of a Recombinant Patchoulol Synthase Variant for Biocatalytic Production of Terpenes

Frister, Thore; Hartwig, Steffen; Alemdar, Semra; Schnatz, Katharina; Thöns, Laura; Scheper, Thomas; Beutel, Sascha (New York City, NY : Springer Humana Press Inc., 2015)

The patchoulol synthase (PTS) is a multi-product sesquiterpene synthases which is the central enzyme for biosynthesis of patchouli essential oil in the patchouli plant. Sesquiterpene synthases catalyse the formation of ...
Downstream processing of high chain length polysialic acid using membrane adsorbers and clay minerals for application in tissue engineering

Bice, Ismet; Celik, Hilal; Wolff, Christopher; Beutel, Sascha; Zahid, Maria; Hitzmann, Bernd; Rinas, Ursula; Kasper, Cornelia; Gerardy-Schahn, Rita; Scheper, Thomas (Weinheim : Wiley-VCH Verlag, 2013)

Polysialic acid (polySia) is a carbohydrate polymer of varying chain length. It is a promising scaffold material for tissue engineering. In this work, high chain length polySia was produced by an Escherichia coli K1 strain ...
Effect of anions on dispersion of a kaolinitic soil clay: A combined study of dynamic light scattering and test tube experiments

Nguyen, M.N.; Dultz, Stefan; Tran, T.T.T.; Bui, A.T.K. (Amsterdam : Elsevier, 2013)

Dispersion is an important issue for clay leaching in soils. In this study, effects of various anions (Cl-, SO42-, acetate, oxalate and citrate) on dispersion of a kaolinitic soil clay were determined at different pH values ...
Effects of soil organic matter properties and microbial community composition on enzyme activities in cryoturbated arctic soils

Schnecker, Jörg; Wild, Birgit; Hofhansl, Florian; Alves, Ricardo J. Eloy; Barta, Jin; Čapek, Petr; Fuchslueger, Lucia; Gentsch, Norman; Gittel, Antje; Guggenberger, Georg; Hofer, Angelika; Kienzl, Sandra; Knoltsch, Anna; Lashchinskiy, Nikolay; Mikutta, Robert; Šantrůčková, Hana; Shibistova, Olga; Takriti, Mounir; Urich, Tim; Weltin, Georg; Richter, Andreas (San Francisco : Public Library of Science, 2014)

Enzyme-mediated decomposition of soil organic matter (SOM) is controlled, amongst other factors, by organic matter properties and by the microbial decomposer community present. Since microbial community composition and SOM ...
Der Einfluss des pH-Wertes auf die Erregbarkeit der Muskulatur und die Entwicklung muskulärer Ermüdung bei hoch intensiver Intervallarbeit mit einer kleinen Muskelgruppe

Hilbert, Michael (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)

[no abstract]
Experimental microbial alteration and Fe mobilization from basaltic rocks of the ICDP HSDP2 drill core, Hilo, Hawaii

Stranghoener, Marius; Schippers, Axel; Dultz, Stefan; Behrens, Harald (Lausanne : Frontiers Media S.A., 2018)

The interaction of a single bacterial species (Burkholderia fungorum) with basaltic rocks from the ICDP HSDP2 drill core and synthetic basaltic glasses was investigated in batch laboratory experiments to better understand ...
Isolierung und Identifizierung der Flavon(ol)glykoside der Endivien (Cichorium endivia L.) und des Kopfsalates (Lactuca sativa L.)

Wöldecke, M.; Herrmann, Karl (Berlin : De Gruyter, 1974)

For the first time, quercetin-3-β-ᴅ-glucuronide, quercetin-3-β-ᴅ-glucoside, quercetin-3-(O-malonyl) -β-ᴅ-glucoside and luteolin-7-/9-ᴅ-glucuronide were isolated from lettuce and kaempferol-3-β-D-glucuronide and ...
One-step-purification of penicillin G amidase from cell lysate using ion-exchange membrane adsorbers

Mönster, Andreas; Villain, Louis; Scheper, Thomas; Beutel, Sascha (Amsterdam : Elsevier, 2013)

This study describes the purification of penicillin G amidase (PGA) by ion exchange membrane adsorbers in a one-step-process. Preliminary experiments with high-throughput screening devices in microliter scale (8-strip ...
PH-responsive release of chlorhexidine from modified nanoporous silica nanoparticles for dental applications

Fullriede, Hendrik; Abendroth, Philipp; Ehlert, Nina; Doll, Katharina; Schäske, Jörn; Winkel, Andreas; Stumpp, Sascha Nico; Stiesch, Meike; Behrens, Peter (Berlin : De Gruyter, 2016)

A pH-sensitive stimulus-response system for controlled drug release was prepared by modifying nanoporous silica nanoparticles (NPSNPs) with poly(4-vinylpyridine) using a bismaleimide as linker. At physiological pH values, ...
Single-use membrane adsorbers for endotoxin removal and purification of endogenous polysialic acid from Escherichia coli K1

de Vries, Ingo; Schreiber, Sarah; Boßmann, Daniel; Hellmann, Zawadi; Kopatz, Jens; Neumann, Harald; Beutel, Sascha (Amsterdam : Elsevier B.V., 2018)

Polysialic acid (polySia) is a promising molecule for various medical applications (e.g., treatment of inflammatory neurodegenerative diseases). In this study a complete production process for human-identical α-(2,8)-linked ...
Studies with lysine N6-hydroxylase. Effect of a mutation in the assumed FAD binding site on coenzyme affinities and on lysine hydroxylating activity

Stehr, Matthias; Smau, Liliana; Singh, Mahavir; Seth, Oliver; Macheroux, Peter; Ghisla, Sandro; Diekmann, Hans (Berlin : De Gruyter, 1999)

The proposed FAD binding site of L-lysine N6-hydroxylase (EC 1.14.13.99) exhibits an unusual proline in a position where a highly conserved glycine is found in other FAD dependent hydroxylases. We have studied the role of ...
Swelling of cell walls in mature sweet cherry fruit : factors and mechanisms

Schumann, Christine; Knoche, Moritz (Heidelberg : Springer, 2020)

Main conclusion: Swelling of sweet cherry cell walls is a physical process counterbalanced by turgor. Cell turgor prevents swelling in intact cells, whereas loss of turgor allows cell walls to swell. Abstract: Swelling of ...
Whole-genome sequences of two new caballeronia strains isolated from cryoturbated peat circles of the permafrost-affected eastern european tundra

Hetz, Stefanie A.; Poehlein, Anja; Horn, Marcus A. (Washington, DC : American Society for Microbiology, 2020)

Annotated genomes of Caballeronia strains SBC1 and SBC2 from acidic permafrost suggest a new species with a facultative lifestyle via oxygen and nitrate respiration. Thus, a contribution to nitrogen cycling in cold and ...
