Abstract: Provided is a process for remedying a contaminated soil characterized in that a contaminated region of the ground is purified by the steps of first freezing the contaminated region, then injecting to the same a microorganism and a liquid agent or gas which is required for a biological treatment using the microorganism's ability to decomposing a pollutant, to enable more efficient and rapid remediation.

Abstract: 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.

Abstract: A survival method for a foreign microorganism, which comprises the steps of disturbing the equilibrium state of an ecosystem in which plural kinds of microorganisms coexist, to temporarily bring the ecosystem into a non-equilibrium state, and then introducing a foreign microorganism into the ecosystem. There are three states of equilibrium involved of which comprise a first state wherein the ecosystem is in equilibrium, a second state wherein the ecosystem is converted to a state which is not in equilibrium, and a third state wherein the ecosystem is converted to a new state of equilibrium to provide for an ecological niche for survival of an introduced foreign microorganism in the ecosystem. The foreign microorganism is also used in a method for remedying an environment contaminated with a pollutant.
