Aliphatic Hydrocarbon Enhances Phenanthrene Degradation by Autochthonous Prokaryotic Communities from a Pristine Seawater

, 2018
The microbial diversity and functioning around oceanic islands is poorly described, despite its importance for ecosystem homeostasis. Here, we aimed to verify the occurrence of microbe-driven phenanthrene co-oxidation in the seawater surrounding the ...

Surfactant Enhanced Bioremediation of Saline Diesel Contaminated Water by a Novel Bacterial Halophilic Consortium

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The use of microorganisms is an evolving method for the degradation of hydrocarbon contaminants. In this aim, halophilic hydrocarbon degrading bacteria were isolated from oil contaminated soil in Tunisia. A lipopeptide biosurfactant produced by Bacillus subtilis SPB1 was tested to increase diesel biodegradation along with co‐inoculation with ...

Genotoxic effect of Phenanthrene on Chironomus sancticaroli (Diptera: Chironomidae)

Zoologia (Curitiba), 2014
Phenanthrene, a Polycyclic Aromatic Hydrocarbon, remains adsorbed to sedimentary particles in aquatic environments. It affects mainly benthic organisms, and is considered potentially genotoxic.

Synthesis and mutagenicity of some cyclopenta[c]phenanthrenes and indeno[c]phenanthrenes [PDF]

Carcinogenesis, 1996
An efficient two-step synthesis of 8(H)-9,10,11,12-tetra-hydrodicyclopenta[a,c]phenanthren-7-one, based on the high pressure Diels-Alder cycloaddition of 4-acetoxy-2-cyclopenten-1-one with 1-(1-naphthyl)cyclopentene and a subsequent dehydrogenation-aromatization reaction, is reported. Further, the synthesis of two cyclopenta[c]-phenanthrenes and indeno[

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.
