“…However, the associations unveiled with our analysis have been experimentally reported in previous studies. Particularly, Pseudomonas , Comamonas , and Acinetobacter species (the main taxa found in the third association) are known to form natural consortia able to degrade a range of recalcitrant compounds such as hydrocarbons 12 , phenolic compounds 13 14 and herbicides 15 . Interestingly, the degradation of these compounds involves similar steps (such as the cleavage of aromatic rings by dioxygenase enzymes 16 ) to those of the degradation pathway of the terpenes present in pinetree resin.…”

We propose a new strategy to identify and visualize bacterial consortia by conducting replicated culturing of environmental samples coupled with high-throughput sequencing and multidimensional scaling analysis, followed by identification of bacteria-bacteria correlations and interactions. We conducted a proof of concept assay with pine-tree resin-based media in ten replicates, which allowed detecting and visualizing dynamical bacterial associations in the form of statistically significant and yet biologically relevant bacterial consortia.

“…Contrarily, the biological recalcitrance of this class of molecules is clearly established, as it was the case for the selected pesticides, by means of the Zahn-Wellens test for the considered substituted ureas isoproturon [36] and diuron [37] as well as for the organophosphorus compound dimethoate [38]. Biodegradation of the organochlorinated 2,4-dichlorophenoxyacetic acid (2,4-D) was only possible after less than 30 days acclimation time [39][40][41] or 12 days acclimation of specific microorganisms for the selected plasticizer, bisphenol A [42,43]. Biological recalcitrance was also reported for the selected triazole and amitrole [17,44].…”

Relevance of Photocatalysis prior to Biological Treatment of Organic Pollutants – Selection Criteria

et al. 2012

International audienceThe relevance of a photocatalytic pretreatment prior to a biological process for removal of organic pollutants was examined. Owing to the significant residual amount and toxicity, amitrole was not relevant. High mineralization allowed to remove bisphenol A and 2,4-dichlorophenoxyacetic acid. Isoproturon and diuron cannot be considered due to the slight evolution of chemical oxygen demand/ total organic carbon (COD/TOC) and average oxidation state during irradiation. After photocatalysis, the ratio of biological oxygen demand (BOD5)/COD remained below the biodegradability limit (0.4) for the rest of the molecules. A favorable COD/TOC trend (decrease during irradiation) was recorded for dimethoate and antibiotics. However, dimethoate and sulfamethoxazole seemed not pertinent due to the long time span for their removal. Since a decrease of toxicity was only recorded for tylosine, it can be selected for subsequent tests
