The Peace-Athabasca Delta (PAD) receives a mixture of hydrocarbons from biogenic, pyrogenic, and petrogenic processes. Source apportionment in the PAD has focussed on polycyclic aromatic compounds (PACs), which are ubiquitous environment susceptible to weathering. In contrast, petroleum biomarkers terpanes, hopanes, steranes degradation-resistant organic found uniquely products that can identif...

Remediation of soils contaminated with petroleum is a challenging task. Four different bioremediation strategies, including natural attenuation, biochar amendment, phytoremediation with ryegrass, and a combination of biochar and ryegrass, were investigated with greenhouse pot experiments over a 90-day period. The results showed that planting ryegrass in soil can significantly improve the remova...

Filter samples of total suspended particle (TSP) collected during a cruise campaign over the northern South China Sea (SCS) from September to October 2013 were analyzed for non-polar organic compounds (NPOCs) as well as organic carbon (OC), elemental carbon (EC) and water-soluble ions. A total of 115 NPOCs species in groups of n-alkanes, polycyclic aromatic hydrocarbons (PAHs), iso-/antiso-alka...

In the presented research we have tested the application of photo ionization detector of ECOPROBE 5 analyzer to monitoring of low concentrations of petroleum products in water. Petroleum products are organic pollutants that are present in wastewater most frequently, which is caused by their broad applications and frequent incidents. Emergency leakage of petroleum and its products is predominant...

(212 words) 1 2 Vibrio furnissii M1 was recently reported to biosynthesize n-alkanes when grown on 3 biopolymers, sugars or organic acids (Park, M. the present study, V. furnissii M1 was subjected to genomic analysis and studied 5 biochemically. The sequence of the 16S rRNA gene and repetitive (REP)-PCR showed 6 that V. furnissii M1 was not identical to other V. furnissii strains tested, but th...

Three bacterial strains of marine origin were isolated during a screening for biosurfactants among n-alkane degrading microorganisms. One strain-identified as Alcaligenes sp. MM1-produced a novel glucose lipid. In the case of Arthrobacter sp. EK 1 the well-known trehalose tetraester was found as major component. From another pure culture classified as Arthrobacter sp. SI 1, extracellular emulsi...

Petroleum is the most common global fossil fuel. It a complex multi-component system mainly composed of various hydrocarbons such as alkanes, cycloalkanes, mono-, bi- and polyaromatic compounds, resins asphaltenes. In spite humanity’s need for petroleum, it negatively affects environment due to its toxicity. The ecological problem especially serious at petroleum mining sites or during transport...
