Abstract
A biological method for removing organic polymers is provided. The method includes the cultivation of a bacterial strain Pseudomonas nitroreducens TX1. The deposit numbers are PTA-6168 at ATCC and BCRC910228 at Bioresources Collection and Research Center in Taiwan (Republic of China). A nitrogen source and inorganic salts are required for bacterial growth. Moreover, the method also provides the information of the supply of air and the water content in soils when this invention is applied to the removal of organic polymers in soils. In addition, the viability of cultivated bacteria is not affected by endogenous bacteria in soils and able to maintain the capacity of degrading organic polymers in the method. The present invention is able to remove the organic polymers in a wide range of amounts effectively and useful in the bioremediation of contamination from organic polymers in both soils and water.
