Indications for acquisition of reductive dehalogenase genes through horizontal gene transfer by Dehalococcoides ethenogenes strain 195

Article Abstract:

The genome of Dehalococcoides ethenogenes strain 195 contains 18 copies of putative reductive dehalogenase genes, including the well-characterized tceA gene whose gene product functions as the key enzyme in the environmentally important dehalorespiration process. The results in the form of a genomic signature revealed several local disruptions of the host signature along the genome sequence.

Isolation, characterization, and ecology of cold-active, chemolithotrophic, sulfur-oxidizing bacteria from perennially ice-covered Lake Fryxell, Antarctica

Article Abstract:

A report on the vertical distribution of cultivable strains of planktonic sulfur-oxidizing bacteria from the water column of the permanently ice-covered Lake Fryxell, Antarctica is described. The results support the hypothesis that biological sulfur cycling is occurring in this polar lake.
