A bacterial strain Pseudomonas sp. a3 capable of degrading nitrobenzene, phenol, aniline, and other aromatics was isolated and characterized. When nitrobenzene was degraded, the release of NH(4) (+) was detected, but not of NO(2) (-). This result implied that nitrobenzene might have a partial reductive metabolic pathway in strain a3. However, aniline appeared as one of the metabolites during th...

In the current study, arrhythmogenic effects of the gap junction inhibitor heptanol (0.05 mM) were examined in Langendorff-perfused mouse hearts. Monophasic action potential recordings were obtained from the left ventricular epicardium during right ventricular pacing. Regular activity was observed both prior and subsequent to application of heptanol in all of the 12 hearts studied during 8 Hz p...

The reaction of [Co(III)(TPP)Cl] (TPP is the dianion of 5,10,15,20-tetra-phenyl-porphyrin) with an excess of 4-nitro-aniline in di-chloro-methane leads to the title compound, [Co(III)(C44H28N4)(C6H6N2O2)2]Cl·CH2Cl2. The Co(III) ion lies on an inversion centre and is octa-hedrally coordinated by two N atoms of the NH2 groups of the two 4-nitro-aniline trans-axial ligands and four pyrrole N atoms...

A biotrickling filter inoculated with commercial mixed microorganisms B350 was employed to treat N-containing odorous vapor - aniline. Results indicated no aniline could be detected when empty bed residence time (EBRT) was larger than 110s at inlet concentration of 0.30 g m(-3). The variation of inlet concentration did not change removal efficiencies when concentration is less than 0.21 g m(-3)...

Cyclodextrins (CD), produced from enzymatic degradation of starch, are a form of biorenewable cyclic oligosaccharide which has an outstanding capability to form inclusion complexes with a variety of molecules including pollutants due to their toroid-shaped molecular structure. In this study, by a simple reprecipitation method, we obtained “channel-type” packing from γ-CD where CD molecules are ...

In the title compound, C(14)H(14)N(2)O(2), the angle between the mean plane of the N-methyl-3-nitro-aniline system (r.m.s. deviation = 0.0185 Å) and the p-tolyl unit is 89.79 (4)°. In the crystal, hydrogen-bonded chains running along [10-1] are generated by the linking of neighbouring mol-ecules via N-H⋯O and C-H⋯O hydrogen bonds involving the 3-nitro-aniline systems and forming R(2) (2)(8) mot...
