Title: | Potential of the TCE-degrading endophyte Pseudomonas putida W619-TCE to improve plant growth and reduce TCE phytotoxicity and evapotranspiration in poplar cuttings | Authors: | WEYENS, Nele TRUYENS, Sascha DUPAE, Joke Newman, Lee Taghavi, Safiyh VAN DER LELIE, Daniel CARLEER, Robert VANGRONSVELD, Jaco |
Issue Date: | 2010 | Publisher: | ELSEVIER SCI LTD | Source: | ENVIRONMENTAL POLLUTION, 158(9). p. 2915-2919 | Abstract: | The TCE-degrading poplar endophyte Pseudomonas putida W619-TCE was inoculated in poplar cuttings, exposed to 0, 200 and 400 mg l(-1) TCE, that were grown in two different experimental setups. During a short-term experiment, plants were grown hydroponically in half strength Hoagland nutrient solution and exposed to ICE for 3 days. Inoculation with P. putida W619-TCE promoted plant growth, reduced TCE phytotoxicity and reduced the amount of TCE present in the leaves. During a mid-term experiment, plants were grown in potting soil and exposed to TCE for 3 weeks. Here, inoculation with P. putida W619-TCE had a less pronounced positive effect on plant growth and ICE phytotoxicity, but resulted in strongly reduced amounts of ICE in leaves and roots of plants exposed to 400 mg l(-1) TCE, accompanied by a lowered evapotranspiration of TCE. Dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA), which are known intermediates of TCE degradation, were not detected. (C) 2010 Elsevier Ltd.
