Comparative genomics of two newly isolated Dehalococcoides strains and an enrichment using a genus microarray.

ABSTRACT: Comparative genomics of Dehalococcoides strains and an enrichment were performed using a microarray targeting genes from all available sequenced genomes of the Dehalococcoides genus. The microarray was designed with 4305 probe sets to target 98.6% of the open-reading frames from strains 195, CBDB1, BAV1 and VS. The microarrays were validated and applied to query the genomes of two recently isolated Dehalococcoides strains, ANAS1 and ANAS2, and their enrichment source (ANAS) to understand the genome-physiology relationships. Strains ANAS1 and ANAS2 can both couple the reduction of trichloroethene, cis-dichloroethene (DCE) and 1,1-DCE, but not tetrachloroethene and trans-DCE with growth, whereas only strain ANAS2 couples vinyl chloride reduction to growth. Comparative genomic analysis showed
