Phenanthrene 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...
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 کاملImpact of methylene chloride on microorganisms and phenanthrene mineralization in soil.
This study investigated the effects of the quantity of methylene chloride, used as a carrier solvent for phenanthrene when added to soil, on phenanthrene mineralization kinetics, soil phospholipid fatty add profiles (PLFA), and phenanthrene distribution. Methylene chloride dosages of 25 microL/g soil or more resulted in an enrichment of saturated PLFAs, suggesting soil microorganisms had adjust...
متن کاملChromone and phenanthrene alkaloids from Dennettia tripetala.
Dennettine, a new 2,6-dimethoxychromone and three known phenanthrene alkaloids (uvariopsine, stephenanthrine and argentinine) in addition to the phenolic and known compound vanillin were isolated from the roots of Dennettia tripetala. Their structures were determined by physical and spectroscopical one dimensional (1D) and 2D-NMR analysis, including heteronuclear multiple bond correlation and n...
