They are induced by the corticosteroid cortexolone and by phenanthrene . " C . elegans " also possesses a lanosterol 14-alpha demethylase, another enzyme in the cytochrome P450 family.

This difference in number of sextets is reflected in the UV absorbance spectra of these two isomers; phenanthrene has a highest wavelength absorbance around 290 nm, while anthracene has highest wavelength bands around 380 nm.

To create such methods, the scientist synthesized the total mellitic acid anhydride, which was found to form orange-red crystals with naphthalene, dark blue with anthracene, brown-red with phenanthrene, and light brown with veratrole.

The carbene is a tungsten carbonyl when used in stoichiometric amounts ( 1 equivalent ) yields 41 % of the phenanthrene "'3.2 "'and when used in catalytic amounts phenanthrene "'3.3 " '.

For example, in phenanthrene one Clar structure has two sextets at the extremities, while the other resonance structure has just one central sextet; therefore in this molecule the outer rings have greater aromatic character whereas the central ring is less aromatic and therefore more reactive.
27.
For example, " R . glutinis " and " R . rubra " have both been found to have a high ability to degrade phenanthrene, while " R . minuta " has been found to degrade benzo ( a ) anthracene.

""'Novosphingobium taihuense " "'is a bacterium from the genus of Novosphingobium which has been isolated from lake sediments from the Taihu Lake in China . " Novosphingobium taihuense " has the ability to degrade phenol, aniline, nitrobenzene, 4-chloronitrobenzene and phenanthrene.
