Sediments from the sulfate-reduction zone of a petroleum-contaminated aquifer, in which benzene persisted, were inoculated with a benzene-oxidizing, sulfate-reducing enrichment from aquatic sediments. Benzene was degraded, with apparent growth of the benzene-degrading population over time. These results suggest that the lack of benzene degradation in the sulfate-reduction zones of some aquifers...

Benzene is a widespread and toxic contaminant. The fate of benzene in contaminated aquifers seems to be primarily controlled by the abundance of oxygen: benzene is aerobically degraded at high rates by ubiquitous microorganisms, and the oxygen-dependent pathways for its breakdown were elucidated more than 50 years ago. In contrast, benzene was thought to be persistent under anoxic conditions un...

The pathways of metabolism of benzene appear to be qualitatively similar in all species studied thus far. However, there are quantitative differences in the fraction of benzene metabolized by the different pathways. These species differences become important for risk assessments based on animal data. Mice have a greater overall capacity to metabolize benzene than rats or primates, based on mass...

This investigation suggested that the qualitative phytochemical compounds based on leaves, flowers and seeds of Anisomeles malabarica with different solvents such as aqueous, benzene, chloroform methanol were used. Aqueous extract including substances like alkaloids, carbohydrate, coumarin, flavonoid, phenol, protein, saponin, steroid, tannin terpenoid had highest concentration phytochemicals c...

The combination of the flexible N,N’-ditopic ligand 1,4-bis(4-pyridylmethyl)benzene (bpymb) with zinc(II) acetate (ZnAc) affords synthesis two-dimensional coordination polymer [Zn2Ac2(μ-Ac)2(bpymb)]n, which was structurally characterized by single crystal XRD. In resolved structure, molar ratio metal:ligand 2:1 for Ac:Zn. However, half units are acting as bridging ligands, allows building a lay...
