Variations in the abundance and identity of class II aromatic ring-hydroxylating dioxygenase genes in groundwater at an aromatic hydrocarbon-contaminated site.

Abstract excerpt

The abundance of genes encoding aromatic ring-hydroxylating dioxygenases (RHDs) in the groundwater at an aromatic hydrocarbon-contaminated landfill near Sydney, Australia, was determined by quantitative DNA-DNA hybridization using class II RHD genes as probes. There were marked differences in hybridization signal intensity against DNA extracted from the groundwater at seven different locations across this...
