A method of biodegrading halogenated alipahtic hydrocarbons is disclosed comprising incubating the hydrocarbons with microorganisms capable of degrading halogenated aliphatic hydrocarbons together with a nontoxic, nongaseous substance that induces the biodegrading activity of said microorganisms. An example of the nontoxic, nongaseous substance is an aromatic amino acid, e.g. tryptophan.
