Geobacter lovleyi sp. nov. strain SZ, a novel metal-reducing and tetrachloroethane-dechlorinating bacterium

Article Abstract:

A bacterial isolate, designated strain SZ, is obtained from noncontaminated creek sediment microcosms based on its ability to derive energy from acetate oxidation coupled to tetrachloroethane (PCE)-to-cis-1,2-dichloroethene (cis-DCE) dechlorination. Substrate versatility, consumption of electron donors to low threshold concentrations, and simultaneous reduction of electron acceptors suggest that strain SZ-type organisms have desirable characteristics for bioremediation applications.

Quantitative PCR confirms purity of strain GT, a novel trichloroethane-to-ethene-respiring Dehalococcoides isolate

Article Abstract:

A novel Dehalococcoides isolate that uses trichloroethene (TCE), cis-DCE, 1, 1-dichloroethene (1, 1-DCE), and vinyl chloride as metabolic acceptors and forms negligible amounts of toxic intermediates during TCE dechlorination. Phylogenetic analysis revealed that strain GT is affiliated with the Pinellas group of the Dehalococcoides cluster and shares 100 percent 16S rRNA gene sequence identity with two other dehalococcoides isolates, strain FL2 and strain CBCD1.
