Biodegradation and detoxification of textile dye Disperse Red 54 by Brevibacillus laterosporus and determination of its metabolic fate

A tritium-adenine suicide procedure was used to select for mutants with reduced uptake of adenine from a population of Chinese hamster V79 cells mutagenized with ethyl methane sulfonate. In one of the mutant lines isolated, designated KC62, the uptake of adenine, hypoxanthine, and guanine was reduced by approximately 70%. The specific activities, K m values, and V max values of adenine phosphoribosyltransferase and of hypoxanthine phosphoribosyltransferase were the same in extracts from KC62 and from the parental cell line. Metabolic fate studies of incorporated [ 3 H]adenine and [ 3 H]hypoxanthine revealed a metabolic block at the level of phosphoribosylation. Determination of phosphoribosylpyrophosphate pool size showed that the mutant contained only 25% of the phosphoribosylpyrophosphate found in the parent. Its reduced availability in KC62 appears to result in a decreased ability to salvage adenine, hypoxanthine, and guaninine via phosphoribosylation. Phosphoribosylpyrophosphate synthetase from KC62 was shown to have an increased sensitivity to inhibition by a variety of nucleotides.

Abstract In the present work, a procedure to determine three textile azo dyes, chromium-complexes [Nylosan Dark Brown (NDB), Lanasyn Dark Brown (LDB), and Lanasyn Red (LR)], from wastewater using solid-phase extraction (SPE) followed by LC-electrospray ionization negative mode tandem mass spectrometry (LC-ESI(–)-MS/MS) has been developed. The extraction/concentration and recovery degree of these dyes from liquid matrices were done on Strata WAX/NH2 cartridges. The chromatographic separation was performed using a Luna C18 (2) 100Å column by isocratic elution with a methanol–acetonitrile–water (0.2% formic acid and 2 mM ammonium formate) mixture. The linearity, the LOD, and the LOQ were determined for each textile dye. The accuracy, the precision (intra- and inter-day), and the matrix effect were also performed for the validation of the developed procedure. These chromium-complex azo dyes often used in the dyeing process by a textile factory in Romania were monitored in the influent and effluent wastewater from a treatment plant situated in its area. Applying the developed SPE-LC-ESI(–)-MS/MS procedure, the following textile dyes were detected (ng/L) in the collected wastewater samples during a 24-h period: NDB 150.1, LDB 200.6, and LR 89.0–244.0 in influents and NDB 22.8, LDB 78.6, and LR 74.0 in effluents.

AbstractThe decolorisation process of a synthetic textile dye, direct violet 51, was investigated in an aqueous solution using an electrochemical method in a batch electrochemical cell. Graphite electrodes were used as the anode and cathode for the decolorisation process. The parameters such as applied current, initial pH, solution conductivity, interfering ions, and effect of electrodes were optimised. It was found that the dye with an initial concentration of 20 mg L−1 could be removed after 50 min using a current of 100 mA with colour removal of up to 94 %. The UV-VIS spectra of the dye were analysed prior to and after treatment and these confirmed that the conjugated systems were decomposed at a current of 100 mA. The optimised method was successfully applied to real wastewater samples.
