Desulfurization of dibenzothiophene by Corynebacterium sp. strain SY1

Article Abstract:

A Corynebacterium sp. was isolated on the basis of its ability to grow with dibenzothiophene (DBT) as the sole source of sulfur. The strain, designated as SY1, could utilize DBT sulfone, dimethyl sulfoxide and dimethyl sulfone. Product characterization showed that SY1 oxidized DBT to DBT-5-oxide and DBT sulfone. These results suggest that SY1 converts organic sulfide to sufoxide and then to sulfone. Based on these results, a new DBT degradation pathway used by Corynebacterium sp. strain SY1 is proposed.

Microbial degradation of dibenzofuran, fluorene, and dibenzo-p-dioxin by Staphylococcus auriculans DBF63

Article Abstract:

The isolation of Staphylococcus auriculans DBF63 is discussed. Dibenzofuran (DBF) was supplied to the strain asa growth substrate and this resulted with the accumulation of salicylic and gentisic acids in the culture broth. Fluorene catabolites were isolated from the culture broth and were identified by the measurement of several physical and chemical properties. Analogous degradation pathways between strain DBF63 and the DBF degraders was established.

Isolation of Terrabacter sp. strain DDE-1, which metabolizes 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene when induced with biphenyl

Article Abstract:

Terrabacter sp. strain DDE-1 can metabolize 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (DDE) in pure culture if induced with biphenyl. The compound is a residue of DDT still is in the environment and limiting land use options. Gas chromatography-mass spectrometry analysis of culture extracts enriched from a DDT residue-contaminated agricultural soil showed various DDE catabolites. Terrabacter sp. strain DDE-1 is an aerobic gram-positive bacterium.
