    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...

    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...

    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...

    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...

    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...

    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...
