In phytoremediation plants are used to support soil microbiota capable of degrading pollutants. I studied the effects of soil pH and glucose supplement on the degradation of phenanthrene (PHE) in soil samples collected from a phytoremediation site consisting of a plantation of different aspen species. The site at Somerharju, Luum\u00e4ki, was originally contaminated with PAH-compounds during creosote impregnation, and the phytoremediation experiment was started by Finnish Natural Resources Centre (LUKE) in 2013. The soil respiration of radiolabelled PHE was studied with the MicrorespTM device in a two-week incubation experiment. Microbial content of soil samples\u2019 was sequenced using next generation sequencing (NGS) of the 16S rRNA gene to explore the differences in the microbiota diversity of the rhizosphere. Both aspen species increased PHE degradation of the rhizosphere soil samples when compared to controls, but no difference was observed between the plots planted with European aspen or hybrid aspen. Soil pH and the addition of glucose did not significantly increase degradation of PHE. Local diversity was largest in soil samples collected from plots without trees, while the plots with trees had more between-samples variation. The results suggest possibilities for the use of the key species P. tremula and targeted bacteria strains in remediation.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-06-09T11:48:44Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-09T11:48:44Z (GMT).
