Pyrene Degradation by Mycobacterium Sp Kms: Biochemical ...
Pyrene, a four-ring polycyclic aromatic hydrocarbon (PAH), was identified as the chemical that requires the largest land area for soil bioremediation due to the slow rate of biodegradation at the Libby, Montana Superfund site.

A. pH-INDUCED CONFORMATIONAL TRANSITIONS OF POLY(METHACRYLIC
ACID) 1. Studies with Pyrene The solubility of pyrene and other polycyclic
hydrocarbons in aqueous solutions was found to be increased two orders of

Polycyclic Aromatic Hydrocarbons: Chemistry and Carcinogenicity
Oxidation of pyrene with sodium dichromate in acetic anhydride-acetic acid gives
a mixture of the pyrene 1,6- and 1,8-diones which are separable only by careful
chromatographic procedures (Cho & Harvey, 1976). Ozonolysis of pyrene ...

Bioaccumulation in Marine Organisms: Effect of Contaminants ...
Benzo(a)pyrene is the best known of the higher molecular weight PAH
carcinogens (Neff, 1979). Most of the benzo(a)pyrene in the environment comes
from pyrolysis of organic matter, though small amounts are present in coal and
petroleum.

Bioconjugate Techniques
Pyrene derivatives can be rather hydrophobic and unsuitable for use in
bioconjugation unless they contain sulfonate groups on the rings, which provide
dramatically increased water solubility. One family of pyrene dyes, termed
Cascade Blue ...

Remediation of Petroleum Contaminated Soils: Biological, ...
Pyrene Pyrene is probably slow to be degraded (Ghisalba, 1983), but doubling
the starting concentration of the compound results in higher degradation rates (
Wiesel, Wuebker, and Rehm, 1993). A sparing effect in the presence of other, ...

Advanced Concepts in Fluorescence Sensing: Part B: ...
Considerations Regarding Pyrene Derivatives as Emission Probes for Macro-
molecules The two principal observables for fluorescence studies of pyrene-
labeled molecules are: (1) relative emission intensity; and (2) the ratio between
the ...

To elucidate the nomenclature of PAHs, the name for benzo(a)pyrene is taken as
an example. Benzo(a) — indicates that an aromatic ring is fused to pyrene in the
a position. A ring can be fused also in positions b, e, and so on. However ...
