Monitoring of functional gene responses to ERD (enhanced reductive dechlorination) from four TCE-contaminated sites

ABSTRACT: A functional microarray targeting 24 genes involved in chlorinated solvent biodegradation pathways has been developed and used to monitor the gene diversity present in four trichloroethylene (TCE) contaminated sites under ERD (enhanced reductive dechlorination) treatment. The microarray format provided by NimbleGen and used in this study is 12x135K. 2 M-BM-5g of labelled gDNA from 30 groundwater samples were hybridized on the microarrays. A 30-chip study was performed, each chip corresponding to hybridization with 2 M-BM-5g of labelled gDNA retrieved from a monitoring well from one of the four contaminated sites. Each probe (760nt) on the microarray was synthesized in eight replicates, and a total of 5,707 random probes was used to determine the background noise. Groundwater samples were
