A biologically pure culture of Pseudomonas cepacia strain KK01 (FERM BP-4235) is capable of degrading trichloroethylene. A method for obtaining microorganisms having a trichloroethylene degrading ability comprises the steps of culturing microorganisms separated from the bodies of termites in a culture medium. A method for remediating a soil contaminated with trichloroethylene comprises the steps of providing a soil contaminated with trichloroethylene and bringing microorganisms having a trichloroethylene degrading ability derived from intestine of termites into contact with the soil, and biodegrading trichloroethylene in the soil. A method for biodegrading trichloroethylene, comprises the steps of culturing Pseudomonas cepacia KK01 (FERM BP-4235) under existence of an inducer and inducing Pseudomonas cepacia KK01 (FERM BP-4235) to have ability for degrading trichloroethylene and bringing Pseudomonas cepacia KK01 having trichloroethylene degrading ability to contact with trichloroethylene and biodegrading trichloroethylene.
