Abstract
Volatile aliphatic chlorinated compounds such as trichloroethylene (TCE), 1, 1, 1-trichloroethane (TCA), and tetrachloroethylene have been detected in groundwater throughout Japan. Various soil and groundwater cleanup technologies are now being developed, studied, and evaluated in Japan. For chlorinated compounds, soil vapor extraction, pumping up and treatment, and digging up and drying are very common approaches. Physical and chemical methods for remediation are expensive. Therefore, less expensive but more complete pollutant destruction technology is required. Bioremediation could be one of the most promising new technologies for cleaning up groundwater contamination, because of its low cost and the complete destruction of pollutants. In this paper, we reported TCE and TCA degrading bacteria and determined their fundamental characteristics for bioremediation.
