Response of the PCB-contaminated soil bacterial community to applied bioremediation treatments
2011
For full field implementation of the bioremediation as a strategy for cleaning PCB-contaminated soils, the impact of the applied treatment on the microbial community needs to be clarified. An ideal bioremediation should have positive effects on PCB-removal but should pose no treats to the health of the soil ecosystem. Microbes, playing an essential role in maintenance of the soil ecosystem, are the first indicators of a negative impact of soil manipulation to ecosystem. A small-scale bioremediation experiment was conducted in order to get insight into behavior of the microbial community during bioremediation of PCB-contaminated soil, targeting both functional PCB-degrading community (by bph…
Unraveling metabolic flexibility of rhodococci in PCB transformation
2021
International audience; Even though the genetic attributes suggest presence of multiple degradation pathways, most of rhodococci are known to transform PCBs only via regular biphenyl (bph) pathway. Using GC-MS analysis, we monitored products formed during transformation of 2,4,4′-trichlorobiphenyl (PCB-28), 2,2′,5,5′-tetrachlorobiphenyl (PCB-52) and 2,4,3′-trichlorobiphenyl (PCB-25) by previously characterized PCB-degrading rhodococci Z6, T6, R2, and Z57, with the aim to explore their metabolic pleiotropy in PCB transformations. A striking number of different transformation products (TPs) carrying a phenyl ring as a substituent, both those generated as a part of the bph pathway and an array…
ASSOCIAZIONE DI SERENOA REPENS, URTICA DIOICA E PINUS PINASTER. SICUREZZA ED EFFICACIA NEL TRATTAMENTO DEI SINTOMI DEL BASSO TRATTO URINARIO. STUDIO …
2010
INTRODUCTION. Serenoa repens (saw palmetto) has been employed for the treatment of lower urinary tract symptoms (LUTS) for several years. Its mechanism of action is believed to be due to antiandrogenic, antiproliferative and antinflammatory properties. An association of Serenoa with the nettle “Utica dioica” showing antiproliferative activity and the pine “Pinus pinaster” derivative, showing antinflammatory action, has been proposed in recent years. Such an action is hoped to act not only by reducing LUTS but also by preventing the development of prostate cancer. MATHERIAL AND METHODS. During the years 2007 and 2008, 320 patients suffering from LUTS were treated with an association of Seren…
