Soil and groundwater remediation utilizing biotechnology

Panasonic provides an advanced bio-remediation service that makes use of the microbes living in the soil in a method of recovering soil/groundwater contaminated by chlorinated volatile organic compounds (CVOCs). In this process, we put "Amteclean," a nutrient salt made from palm oil, into the soil/groundwater. It activates the CVOC decomposition functions of the microbes living there. Although this new method requires a longer period than excavating the contaminated soil and replacing it with clean soil, it has less effect on ecosystems and is more affordable.
   It is essential that the decomposing bacteria are present in the soil/groundwater for its remediation process. Although conventional methods have been unable to identify the optimum type and amount of decomposing bacteria, Microarray Technology,^* developed in 2005, enables us to determine the presence of suitable decomposing bacteria and identify 22 bacteria types in a single test.
