AIM To select carbazole-degrading bacteria able to survive and metabolize carbazole in biphasic organic-water media and to study the factors affecting carbazole degradation in such conditions. METHODS AND RESULTS In this research a new carbazole-degrading strain was isolated from hot springs in Mexico. This bacterium was preliminary identified as Burkholderia sp. IMP5GC and was able to grow u...

The title compound, C(21)H(21)NO, consists of a carbazole skeleton with a meth-oxy-benzene ring fused to the carbazole, and a butyl group attached to the carbazole N atom. The carbazole skeleton is nearly planar [maximum deviation = 0.078 (2) Å], and it is oriented at a dihedral angle of 4.22 (4)° with respect to the adjacent meth-oxy-benzene ring.

A carbazole-based triple bridging ligand (LH) consisting of two imidazole moieties at 3,6 positions with a diketone unit at the carbazole nitrogen forms carbazole-bridged zinc(II) complexes with structures of [(L(-))4(Zn(2+))n] (n = 2-6), where the strength of aromatic stacking interactions between the carbazole rings increases with an increase in the number of Zn(2+) ions bridged by the imidaz...

The synthesis, structure and biological activity of carbazole compounds has been long focus of research interests in the field of medicinal chemistry. 5,8-dibromo-5,6-dihydro(3,2-a)carbazole A have prepared in good yield by a free radical bromination reaction of 8-bromo-5,6-dihydro9(3,2-a)carbazole with N-bromosuccinimide in carbontetrachloride at ambient temperature.. Compound 2 have prepared ...

The last two decades had witnessed extensive investigation on bacterial degradation of carbazole, an N-heterocyclic aromatic hydrocarbon. Specifically, previous studies have reported the primary importance of angular dioxygenation, a novel type of oxygenation reaction, which facilitates mineralization of carbazole to intermediates of the TCA cycle. Proteobacteria and Actinobacteria are the pred...

In a previous study, three bacterial strains isolated from tropical hydrocarbon-contaminated soils and phylogenetically identified as Achromobacter sp. strain SL1, Pseudomonas sp. strain SL4 and Microbacterium esteraromaticum strain SL6 displayed angular dioxygenation and mineralization of carbazole in batch cultures. In this study, the ability of these isolates to survive and enhance carbazole...

Carbazole is a class of phytochemical associated with cancer prevention. It attracted a significant interest in recent time for their usefulness in synthetic heterocyclic chemistry, analytical chemistry and pharmacology. The aim of the study was to evaluate the impact of biofield energy treatment on carbazole by various analytical methods. The study was performed in two groups i.e. control and ...

Cloud point extraction (CPE) as a rapid, simple and efficient method coupled with high performance liquid chromatography (HPLC) was used for sample preparation and subsequent determination of carbazole, trinitrocarbazole (TrNC) and tetra nitro carbazole (TNC) in water samples. Some effective parameters on extraction, such as volume of Triton X-100, extraction time, extraction temperature, ionic...
