Abstract: An exhaust gas decomposition apparatus or system that includes a bioreactor fluorine-containing compound is decomposed by contact with the first and second fluids in the bioreactor. The first fluid is supplied through a bioreactor inlet and is exhausted through the bioreactor outlet, and moves in a first direction in the bioreactor. The first or second fluid includes a biological catalyst such as an enzyme or recombinant microbe, while the other fluid includes a fluorine-containing compound. As a result, the fluorine-compounds is efficiently biologically remediated by the biological catalyst.
