Genes encoding an aniline dioxygenase of Frateuria sp. ANA-18, which metabolizes aniline via the ortho-cleavage pathway of catechol, were cloned and named tdn genes. The tdn genes were located on the chromosomal DNA of this bacterium and weren't clustered with catechol-degrading gene clusters. These results show that the ANA-18 aniline-degrading gene cluster is constructionally different from P...
Background & Aims of the Study: There are three different types of fibers used in the manufacture of various textile products: cellulose fibers, protein fibers and synthetic fibers. Textile wastewater discharge into the environment leads to irreparable damages. The main purpose of this study was treatment of textile wastewater, using a combined coagulation and dissolved air flotation (DAF) ...
In a neat electron-donating solvent (in this case aniline), photoinduced electron transfer (PET) from the solvent to an excited acceptor (e.g. a coumarin fluorophore) may be anticipated to be the most efficient because of the close contact of the acceptor with many donors. Addition of an inert component would most likely retard the PET process by replacing some donors from the neighbourhood of ...
Background. Present study was designed to evaluate the protective effects of protocatechuic acid alone and in combination with ascorbic acid in aniline hydrochloride induced spleen toxicity in rats. Materials and Methods. Male Wistar rats of either sex (200-250 g) were used and divided into different groups. Spleen toxicity was induced by aniline hydrochloride (100 ppm) in drinking water for a ...
Multi-walled carbon nanotubes (MWCNTs) were used in the adsorptive removal of aniline, an organic pollutant, from an aqueous solution. It was found that carbon nanotubes with a higher specific surface area adsorbed and removed more aniline from an aqueous solution. The adsorption was dependent on factors, such as MWCNTs dosage, contact time, aniline concentration, solution pH and temperature. T...
The ability of some bacteria and filamentous fungi to degrade aniline and its derivatives was reported earlier in the literature. However, there was no information about the biodegradation of aniline by yeast strains. The present work is focused on yeast strain Candida methanosorbosa BP-6 which was isolated from the wastewater pool of the old dye factory "Boruta" in Zgierz by enrichment techniq...
Aniline and o-, m-, and /Moluidine, which are representative of aro matic amines in cigarette smoke, were identified and quantified in human urine. Smokers excreted 3.1 ±2.6 «¿g/24 h of aniline and 6.3 ±3.7 ¿ig/ 24 h of o-toluidine (n = 16). Nonsmokers excreted 2.8 ±2.5 Mg/24 h of aniline and 4.1 ±3.2 un; 24 h of o-toluidine (n = 12). Metaand /»toluidine were detected in the urine of 2 ...
برهمکنش رنگینه آزور a با پلی نوکلئوتیدهای سنتزی poly [ ( a-t ) ] و poly [ ( g-c ) ]و دزوکسی ریبونوکلئیک اسید (dna) غده تیموس گوساله در در بافر فسفات 5/7 میلی مولار با ph 2/7 با استفاده از تکنیک اسپکتروسکوپی جذب نوری مطالعه شده است. اثرات هیپوکرومیک قوی در طیف جذبی و وجود نقطه ایزوبستیک در طیف uv-vis تیتراسیون رنگینه با پلی نوکلئوتید poly [ ( g-c ) ] یک برهمکنش همگن را تایید می کند . ثابت های ظ...
We have characterized a novel microorganism, strain HY99, which is capable of aerobic and anaerobic degradation of aniline. Strain HY99 was found to aerobically metabolize aniline via catechol and 2-hydroxymuconic semialdehyde intermediates, and to transform aniline via p-aminobenzoate in anaerobic environments. Physiological and biochemical tests revealed that strain HY99 was most similar to D...
Wearable dry electrodes are required for long-term biopotential recordings, but their availability is limited. The diagnosis of coronary heart disease possible with ambulatory electrocardiography (ECG). For ECG sensing, on-skin used by conformably contacting the skin’s moving and arbitrary formed surface. However, low skin-adhesion restricts use in sensing an extended period time. Here, it was ...
