Reductive dechlorination of chlorinated ethenes and 1,2-dichloroethane by "Dehalococcoides ethenogenes" 195
Article Abstract:
'Dehalococcoides ethenogenes' 195 can reductively dechlorinate tetrachloroethane (PCE) completely to ethene. When PCE-grown strain 195 was transferred into growth medium added with trichloroethene (TCE), cis-dichloroethene (DCE), 1,1-DCE, or 1,2-dichloroethane (DCA) as an electron acceptor, these chlorinated compounds were consumed at increasing rates over time, which suggested that growth occurred. Moreover, the number of cells increased when TCE, 1,1-DCE or DCA were present.

Phenotypic and phylogenetic characterization of ruminal tannin-tolerant bacteria
Article Abstract:
A study was conducted to analyze 16S rRNA sequences and selected phenotypic properties for isolated bacteria that have the ability to tolerate high levels of hydrolyzable and condensed tannins. The bacteria were determined from the ruminal contents of animals in various geographic sites. Experimental results indicated that the presence of tannin-tolerant bacteria is not hindered by climate, geography or host animal.

Characterization of hydrogenase and reductive dehalogenase activities of Dehalococcoides ethenogenes strain 195
Article Abstract:
The analysis of the location and activities of trichloroethene (TCE)-reductive dehalogenase (RD) and hydrogenase in whole cells and cell extracts of Dehalococcoides ethenogenes is described. It is seen that the Dehalococcoides ethenogenes strain 195 reductively dechlorinates tetrachloroethane (PCE) and trichloroethene (TCE) to vinyl chloride and ethene using H2 as an electron donor.
