Next to carbohydrates, aromatic compounds are the second most abundant class of natural organic molecules in living organic matter but also make up a significant proportion of fossil carbon sources. Only microorganisms are capable of fully mineralizing aromatic compounds. While aerobic microbes use well-studied oxygenases for the activation and cleavage of(More)
Benzoyl-coenzyme A (CoA) reductases (BCRs) are key enzymes in the anaerobic degradation of aromatic compounds and catalyse the reductive dearomatization of benzoyl-CoA to cyclohexa-1,5-dienoyl-1-carboxyl-CoA. Class I BCRs are ATP-dependent FeS enzymes, whereas class II BCRs are supposed to be ATP-independent and contain W, FeS clusters, and most probably(More)
The physiology of the response in the methanotrophic bacterium Methylococcus capsulatus Bath towards thermal and solvent stress was studied. A systematic investigation of the toxic effects of organic compounds (chlorinated phenols and alkanols) on the growth of this bacterium was carried out. The sensitivity to the tested alkanols correlated with their(More)
Aromatic compounds are widely distributed in nature and can only be biomineralized by microorganisms. In anaerobic bacteria, benzoyl-CoA (BCoA) is a central intermediate of aromatic degradation, and serves as substrate for dearomatizing BCoA reductases (BCRs). In facultative anaerobes, the mechanistically difficult reduction of BCoA to(More)
Desulfotomaculum gibsoniae is a mesophilic member of the polyphyletic spore-forming genus Desulfotomaculum within the family Peptococcaceae. This bacterium was isolated from a freshwater ditch and is of interest because it can grow with a large variety of organic substrates, in particular several aromatic compounds, short-chain and medium-chain fatty acids,(More)
