Abstract
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.
Claims8
A biologically pure culture of the bacterial strain Pseudomonas putida TX2 (BCRC 910232) which degrades the organic polymers alkylphenol polyethoxylates, polyethylene glycol, dodecy octaethoxylate, 1,4-dioxane, trioxane or cyclic ethers, and the environmental hormone alkylphenols, and which is capable to grow in a culture medium containing alkylphenol polyethoxylates with a concentration of about 0.05% to about 20%.
