Fungal Strains as Catalysts for the Biotransformation of Halolactones by Hydrolytic Dehalogenation with the Dimethylcyclohexane System [PDF]
Bicyclic chloro-, bromo- and iodo-γ-lactones with dimethylcyclohexane rings were used as substrates for bioconversion by several fungal strains (<em>Fusarium</em>, <em>Botrytis</em> and <em>Beauveria</em>). Most of the

Structural basis for the hydrolytic dehalogenation of the fungicide chlorothalonil. [PDF]
Cleavage of aromatic carbon-chlorine bonds is critical for the degradation of toxic industrial compounds. Here, we solved the X-ray crystal structure of chlorothalonil dehalogenase (Chd) from Pseudomonas sp. CTN-3, with 15 of its N-terminal residues truncated (ChdT), using single-wavelength anomalous dispersion refined to 1.96 Å resolution. Chd has low

Microbial Dehalogenation of Synthetic Organohalogen Compounds: Hydrolytic Dehalogenases [PDF]
Hydrolytic removal of halogen substitutents is commonly the first step in the degradation of haloaliphatic compounds by aerobic bacteria, whereas initial dehalogenation of aryl halides is rare.

The Operon Encoding Hydrolytic Dehalogenation of 4-Chlorobenzoate Is Transcriptionally Regulated by the TetR-Type Repressor FcbR and Its Ligand 4-Chlorobenzoyl Coenzyme A [PDF]
The bacterial hydrolytic dehalogenation of 4CBA is a special CoA-activation-type catabolic pathway that plays an important role in the biodegradation of polychlorinated biphenyls and some herbicides. With genetic and biochemical approaches, the present study identified the transcriptional repressor and its cognate effector of a 4CBA hydrolytic ...

Community-integrated multi-omics facilitates screening and isolation of the organohalide dehalogenation microorganism [PDF]
Summary: A variety of anthropogenic organohalide contaminants generated from industry are released into the environment and thus cause serious pollution that endangers human health.

Hydrolytic dehalogenation of the chlorothalonil isomer o-tetrachlorophthalonitrile by Pseudochrobactrum sp. BSQ-1 [PDF]
Abstract Microbial dehalogenation plays key roles in the biodegradation and detoxification of halogenated aromatics. Although the hydrolytic dehalogenation of halogenated aliphatic hydrocarbons and carboxylic acids has been extensively studied, there are few reports on the hydrolytic dehalogenation of halogenated aromatics. In this study, the aerobic

Identification of genes coding for hydrolytic dehalogenation in the metagenome derived from a denitrifying 4-chlorobenzoate degrading consortium [PDF]
A metagenomic approach was taken to investigate the genetic basis for the ability of an anaerobic consortium to grow on either 4-chlorobenzoate or 4-bromobenzoate under denitrifying conditions. Degenerate PCR primers were designed for the family of 4-chlorobenzoyl-CoA dehalogenase genes.

New Hydroxylactones and Chloro-Hydroxylactones Obtained by Biotransformation of Bicyclic Halolactones and Their Antibacterial Activity [PDF]
The aim of this study was to obtain new halolactones with a gem-dimethyl group in the cyclohexane ring (at the C-3 or C-5 carbon) and a methyl group in the lactone ring and then subject them to biotransformations using filamentous fungi.

Reductive dechlorination of 2,4-dichlorobenzoate to 4-chlorobenzoate and hydrolytic dehalogenation of 4-chloro-, 4-bromo-, and 4-iodobenzoate by Alcaligenes denitrificans NTB-1 [PDF]
Alcaligenes denitrificans NTB-1, previously isolated on 4-chlorobenzoate, also utilized 4-bromo-, 4-iodo-, and 2,4-dichlorobenzoate but not 4-fluorobenzoate as a sole carbon and energy source. During growth, stoichiometric amounts of halide were released.
