petroleum-polluted soil samples from ahvaz oilfield were enriched, using three methods to detect microorganisms with different dibenzothiophene degradation capabilities. strain nisoc-03, a nitrate-reducing, oxidase negative, catalase, citrate, and urease positive, gram negative rod, showed interesting dibenzothiophene desulfurization behavior, designated as entreobacter sp. strain nisoc-03 base...

Numerous contributions have been made to our knowledge of the process of conjugation of phenol in vivo (2, 3). The studies in vitro are related to the formation of either phenyl sulfate (4-6) or glucuronide (7-11). Because of the great difference in behavior towards hydrolysis of the sulfate and the glucuronide (12), the formation of phenyl sulfate and phenyl glucuronide can be followed simulta...

silica chloride converted benzyl or tert-butyl esters to the corresponding acid chlorides and alkyl chlorides. it also converted benzyl or tert-butyl phenyl ethers to the corresponding allcyl chlorides and phenol

In the title compound, C23H18BrN3OS·0.5H2O, the bromo-phenyl, phenyl and phenol rings make dihedral angles of 46.5 (1), 66.78 (8) and 15.4 (2)°, respectively, with the mean squares plane of the thia-zol-idene ring. In the crystal, the lattice water mol-ecule is hydrogen bonded to the phenol group and makes a weaker O-H⋯N connection to an inversion-related mol-ecule, forming a ring while weak pa...

The mol-ecule of the title compound, C21H17N3O, is built up from fused five- and six-membered rings connected to a methyl group, a phenyl ring and an (imino-meth-yl)phenol group. The fused ring system is almost planar (r.m.s. deviation = 0.031 Å) and forms dihedral angles of 64.97 (7) and 18.52 (6)° with the phenyl ring and the (imino-meth-yl)phenol group, respectively. In the crystal, centrosy...

On the biotransformation of phenol and monofluorophenols by the cultured cells of Eucalyptus perriniana, phenyl and fluorophenyl b-D-glucosides were isolated after a 1-h incubation. Especially, the yield of 2-fluorophenol is higher than those of the other substrates, i.e., phenol, 3and 4-fluorophenols. These results indicated that E. perriniana cells selectively glycosylate the hydroxyl group o...

The title compound, C(19)H(19)ClO(5), displays a dihedral angle of 74.7 (3)° between the mean planes of the 4-chloro-phenyl and phenol rings.
