Degradation kinetics of phenanthrene
and naphthalene by C1Fd strain are presented in Fig.
(98%) and n-tetradecane (olefin free, [greater than or equal to] 99.
The objective of the study were the (a) isolation of potential biosurfactant producing bacteria based on their capability of reduction in surface tension and emulsification index and (2) determination of growth of selected isolate on phenanthrene
amended media as possible indicator for bioremediation of hydrocarbon contaminated sites.
Dichloromethane extracts of all afore mentioned carbonaceous raw materials contained traces of cyclic hydrocarbons, benzene and its derivatives, naphthalene and its methyl-, dimethyl- and trimethyl derivatives, phenanthrene
, anthracene and their derivatives, and long chain aliphatic unbranched and branched hydrocarbons.
In present study the hydrocarbon degrading bacterial strains were isolated from petrol contaminated soil of Karachi and the isolated bacterial strains were identified and checked for their biodegradation capabilities for aromatic hydrocarbons (xylene, phenanthrene
, naphthalene, biphenyl and anthracene) which are deleterious for both biotic and abiotic flora by means of enumeration using spread plate method.
The largest difference in liquid phase samples was observed in Anthracene (5 times) and Phenanthrene
(2 times) compounds, whereas the largest difference in solid samples was observed in Pyrene (2.
EPA 2013); dibenzofuran, phenanthrene
, and pyrene are classified as group D "not classifiable as to human carcinogenicity" (U.
Furthermore, by scanning electron microscopy, abundant coccolithophores have been found in the Biluo Co oil shale, which indicates the contribution of the abundant phenanthrene
In addition, the environmental protection agency (EPA) has set up an index of air pollution that refers to sixteen PAHs including naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene
, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, dibenzo(a,h)anthracene, benzo(ghi)perylene, indeno(1,2,3-cd) pyrene, benzo(a)pyrene, etc.
5%, CEWAF, WAF), and phenanthrene
made a smaller but still measurable component (2.
After 30 days, the plants digested up to 50 percent of the phenanthrene
in spiked soil, the team reports October 9 in Environmental Science & Technology.
Researchers are still not sure how these chemicals, as well as others (Bisphenol A, phthalates, phenanthrene
