Fungal Strains as Catalysts for the Biotransformation of Halolactones by Hydrolytic Dehalogenation With the Dimethylcyclohexane System [PDF]
Molecules, 2012 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

Microbial Dehalogenation of Synthetic Organohalogen Compounds: Hydrolytic Dehalogenases [PDF]
Chimia, 1993 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.

New Hydroxylactones and Chloro-Hydroxylactones Obtained by Biotransformation of Bicyclic Halolactones and Their Antibacterial Activity [PDF]
MoleculesThe 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.
