ABSTRACT:
An apparatus and method for increasing the rate of oxidation of toxic vapors by methanotrophic bacteria. The toxic vapors of interest are methane and trichloroethylene. The apparatus includes a gas phase bioreactor within a closed loop pumping system or a single pass system. The methanotrophic bacteria include Methylomonas methanica, Methylosinus trichosporium, and uncharacterized environmental enrichments.
