Effects of Solution Chemistry on the Partitioning of Phenanthrene to Sorbed Surfactants
Solution chemistry effects on surfactant micelle formation, surfactant sorption on kaolinite, and phenanthrene partitioning to surfactant micelles and sorbed surfactants were studied. For the anionic surfactant sodium dodecyl sulfate (SDS), critical micelle concentration (cmc) values decreased with increasing ionic strength but were unaffected by pH changes. For the nonionic surfactant Tween 80...
متن کاملThe Halophyte Cakile maritima Reduces Phenanthrene Phytotoxicity.
In a previous study, we showed that the halophyte plant model Thellungiella salsuginea was more tolerant to phenanthrene (Polycyclic Aromatic Hydrocarbon: PAH) than its relative glycophyte Arabidopsis thaliana. In the present work, we investigated the potential of another halophyte with higher biomass production, Cakile maritma, to reduce phenanthrene phytotoxicity. Sand was used instead of ara...
متن کامل2,3:6,7-Bis(methylenedioxy)phenanthrene
In the title mol-ecule, C(16)H(10)O(4), all the non-H atoms are coplanar. The crystal structure is stabilized by weak inter-molecular C-H⋯O contacts and π-π stacking inter-actions (the inter-planar distance is 3.43 Å).
متن کاملBioremediation of Phenanthrene Polluted Soils
The best metabolic conditions for the biodegradation of hydrocarbons by a selected microbial consortium from a natural soil were investigated in order to improve the efficiency of bioremediation processes for cleaning of polluted waters and soils. Phenanthrene is one of the most recalcitrant pollutants to microbial decomposition and most difficult to remove. A microbial consortium was selected ...
متن کاملPhenanthrene degradation in soils co-inoculated with phenanthrene-degrading and biosurfactant-producing bacteria.
Contaminant sorption within the soil matrix frequently limits biodegradation. However, contaminant bioavailability can be species-specific. This study investigated bioavailability of phenanthrene (PHE) to two PHE-degrading bacteria (Pseudomonas strain R and isolate P5-2) in the presence of rhamnolipid biosurfactant and/or a biosurfactant-producing bacterium, Pseudomonas aeruginosa ATCC 9027. Ps...
