title: Use of an internal standard in monitoring the bacterial degradation of crude oil.
abstract: Hexachloroethane is nonvolatile, insoluble in water, and apparently not toxic to or metabolized by bacteria. Its addition to cultures growing at the expense of crude oil thus provides an internal standard against which the rate of degradation of individual crude oil components can be conveniently and reproducibly measured.
