Predicting the occurrence of monooxygenases and their associated phylotypes in soil microcosms

Cometabolic oxidation involves the oxidation of chemicals often by monooxygenases or dioxygenases and can be a removal process for environmental contaminants such as trichloroethene (TCE) or 1,4-dioxane. Information on the occurrence of these genes and their associated microorganisms in environmental samples has the potential to enhance our understanding of contaminant removal. The overall aims were to 1) ascertain which genes encoding for monooxygenases (from methanotrophs, ammonia oxidizing bacteria and toluene/phenol oxidizers) and other key enzymes are present in soil microcosms and 2) determine which phylotypes are associated with those genes.
