Introducing excess body weight in childhood and adolescence and comparison with body mass index and waist-to-height ratio

Weight status in children and adolescents is commonly defined using age- and gender-corrected standard deviation scores for body mass index (BMI-SDS, also called z-scores). Values are not reliable for the extreme...

Laccase-induced derivatization of unprotected amino acid L-tryptophan by coupling with p-hydroquinone 2,5-dihydroxy-N-(2-hydroxyethyl)-benzamide

We have studied the enzymatic derivatization of amino acids by use of the polyphenol oxidase laccase. Derivatization of L-tryptophan was achieved by enzymatic crosslinking with the laccase substrate 2,5-dihydr...

Detoxification of ferulic acid by ectomycorrhizal fungi

The ectomycorrhizal fungi Laccaria amethystina and Lactarius deterrimus grown in liquid culture were used to study the fate of added ferulic acid. Laccaria amethystina degraded ferulic acid to the major metabolit...

Extracellular degradation of phenol by the cyanobacterium Synechococcus PCC 7002

Investigations of the unicellular marine cyanobacterium Synechococcus PCC 7002 revealed its ability to metabolize phenol under non-photosynthetic conditions up to 100 mg L⁻¹. Under continuous light, photoautotrop...

Laccase-catalysed synthesis of coupling products of phenolic substrates in different reactors

Substrate oxidation of aromatic substances by the enzyme laccase followed by a heteromolecular coupling with a co-substrate is a promising possibility for the synthesis of new compounds. To find a suitable re...

Molecular analysis of aerobic phenylacetate degradation in Azoarcus evansii

The Azoarcus evansii gene which codes for phenylacetate-CoA ligase, an enzyme involved in the aerobic degradation of phenylacetate, was isolated from a genomic library, using as the probe a fragment of the gene ...

Cometabolic ring fission of dibenzofuran by Gram-negative and Gram-positive biphenyl-utilizing bacteria

Thirty-five strains of soil bacteria were grown with biphenyl (BP) and tested for their capacity to cooxidize dibenzofuran (DBF). During metabolism of DBF, the culture medium of 17 strains changed from colorl...

Formation of glucoside conjugates during biotransformation of dibenzofuran by Penicillium canescens SBUG-M 1139

Penicillium canescens oxidises dibenzofuran (DBF) to produce monohydroxylated derivatives and other more hydrophilic metabolites. These substances are water-soluble but unstable in organic solvents such as ethyl...

Methyl ketone formation during degradation of phenoxybutyric acid by Penicillium canescens SBUG-M 1139

Penicillium canescens SBUG-M 1139 was shown to be able to grow using phenoxybutyric acid as the sole carbon source. The rapid conversion of the phenoxyalkanoic acid resulted in the forma...

Biodegradation of biphenyl by the ascomycetous yeast Debaryomyces vanrijiae

Cells of the yeast strain Debaryomyces vanrijiae SBUG 770, grown with glucose, converted biphenyl to 4-hydroxybiphenyl as the major metabolite. In addition, 2-hydroxybiphenyl was formed in minor amounts. No furt...

Signal source impedance of implanted pacemaker electrodes estimated from the spectral ratio between loaded and unloaded electrograms in man

The signal source impedance Z of implanted pacemaker electrodes plays an important role for adequate sensing of electrogram signals and has so far been little explored. A frequency-domain method for thein vivo ca...
