An emerging groundwater remediation practice area is cometabolic bioremediation. This approach “has been used on some of the most recalcitrant contaminants, e.g., PCE, TCE, MTBE*, TNT, dioxane, and atrazine. Methanotrophs have been demonstrated to produce methane monooxygenase, an oxidase that can degrade over 300 compounds (see table below). Cometabolic bioremediation also has the advantage of being able to degrade contaminants to trace concentrations, since the biodegrader is not dependent on the contaminant for carbon or energy.” (Hazen 2009) inVentures Technologies’ family of groundwater remediation products based on the worldwide-patented Gas inFusion technology, which allows for supersaturated levels of dissolved gas into liquids, is ideal for many cometabolic bioremediation projects.
