Risk/benefit evaluation of the use of triclosan in surgical suturing materials (2006)

Kramer, Axel, Assadian, Ojan, Guggenbichler, Josef Peter, Heidecke, Claus-Dieter, Jünger, Michael, Lippert, Hans, ...

Based on the current literature, a risk/benefit analysis of the antimicrobial impregnation of surgical sutures with triclosan is performed, focussing on efficacy and indication, risk of resistance...

Transformation of Triclosan by Trametes versicolor and Pycnoporus cinnabarinus

Hundt, Kai, Martin, Dierk, Hammer, Elke, Jonas, Ulrike, Kindermann, Markus Karl, Schauer, Frieder

We investigated the ability of Trametes versicolor and Pycnoporous cinnabarinus to metabolize triclosan. T. versicolor produced three metabolites, 2-O-(2,4,4′-trichlorodiphenyl...

Cometabolic Degradation of Dibenzofuran by Biphenyl-Cultivated Ralstonia sp. Strain SBUG 290†

Becher, Dörte, Specht, Michael, Hammer, Elke, Francke, Wittko, Schauer, Frieder

Cells of the gram-negative bacterium Ralstonia sp. strain SBUG 290 grown in the presence of biphenyl are able to cooxidize dibenzofuran which has been 1,2-hydroxylated. Meta cleavage of the...

Biotransformation of Biphenyl by Paecilomyces lilacinus and Characterization of Ring Cleavage Products

Gesell, Manuela, Hammer, Elke, Specht, Michael, Francke, Wittko, Schauer, Frieder

We examined the pathway by which the fungicide biphenyl is metabolized in the imperfect fungus Paecilomyces lilacinus. The initial oxidation yielded the three monohydroxylated biphenyls. Further...

Novel Ring Cleavage Products in the Biotransformation of Biphenyl by the Yeast Trichosporon mucoides

Sietmann, Rabea, Hammer, Elke, Specht, Michael, Cerniglia, Carl E., Schauer, Frieder

The yeast Trichosporon mucoides, grown on either glucose or phenol, was able to transform biphenyl into a variety of mono-, di-, and trihydroxylated derivatives hydroxylated on one or both aromatic...

Dehalogenation of Chlorinated Hydroxybiphenyls by Fungal Laccase

Schultz, Asgard, Jonas, Ulrike, Hammer, Elke, Schauer, Frieder

We have investigated the transformation of chlorinated hydroxybiphenyls by laccase produced by Pycnoporus cinnabarinus. The compounds used were transformed to sparingly water-soluble colored...

Isolation and Characterization of a Dibenzofuran-Degrading Yeast: Identification of Oxidation and Ring Cleavage Products

Hammer, Elke, Krowas, Dirk, Schäfer, Annett, Specht, Michael, Francke, Wittko, Schauer, Frieder

We characterized the ability of a yeast to cleave the aromatic structure of the dioxin-like compound dibenzofuran. The yeast strain was isolated from a dioxin-contaminated soil sample and identified...

Synthesis of Imidazol-2-yl Amino Acids by Using Cells from Alkane-Oxidizing Bacteria

Mikolasch, Annett, Hammer, Elke, Schauer, Frieder

Sixty-one strains of alkane-oxidizing bacteria were tested for their ability to oxidize N-(2-hexylamino-4-phenylimidazol-1-yl)-acetamide to imidazol-2-yl amino acids applicable for pharmaceutical...

Simultaneous Degradation of Atrazine and Phenol by Pseudomonas sp. Strain ADP: Effects of Toxicity and Adaptation

Neumann, Grit, Teras, Riho, Monson, Liis, Kivisaar, Maia, Schauer, Frieder, Heipieper, Hermann J.

The strain Pseudomonas sp. strain ADP is able to degrade atrazine as a sole nitrogen source and therefore needs a single source for both carbon and energy for growth. In addition to the typical C...
