    摘要: A method for cleavage of the ether-linkage of polyethoxylates is described. A novel pure microbial culture, Pseudomonas nitroreducens TX1 (Depository No.: BCRC910228), is used under aerobic condition to cleave the ether-linkage adjacent to the carboxylated terminus or ethoxyl terminus. This method is useful to cleave sequentially ether-linkage of polyethoxylates in an aqueous buffer solution with an initial concentration of the polyethoxylates between 0.05% and 20%. This method is also effective for the cleavage of the ether-linkages in short-chain polyethoxylates with one to three ethoxyl units.

    摘要: A Gram-negative bacterial strain, Pseudomonas putida TX2 (PTA-6169 and BCRC 910232), was isolated from farmland, which had received frequent applications of a various pesticides and surfactants. This strain was demonstrated to have the capacity to grow on alkylphenol polyethoxylates (0.05% to 20%) or alkylphenol (0.001% to 0.01%) as sole source of carbon and energy. The metabolic activity of this strain can be applied in the degradation of organic polymers containing ethoxylate units, alkylphenol and alkylphenol derivatives.

    摘要: 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.
