The ligninolytic enzyme system of Phanerochaete chrysosporium decolorizes several recalcitrant dyes. Three isolated lignin peroxidase isoenzymes (LiP 4.65, LiP 4.15, and LiP 3.85) were compared as decolorizers with the crude enzyme system from the culture medium. LiP 4.65 (H2), LiP 4.15 (H7), and LiP 3.85 (H8) were purified by chromatofocusing, and their kinetic parameters were found to be simi...

Abstract Photocatalytic degradation of pollutants using nano-TiO 2 is one the most promising strategies to solve environmental pollution problems. In this paper, we systematically studied Bi WO 6 composited TiO nanowires obtain optimum composite proportion. Moreover, were with MoO and / in proportion, respectively. The results showed that had best catalytic performance, rate methyl orange reach...

Since the early ages, human beings have used colored materials to leave marks on their environment and following generations. In time, paints, which gained great importance with painting objects items they used, brought environmental problems them. Synthetic paints/dyes meet increasing need over time had be eliminated from environment. Nowadays, using bacteria is considered as a good solution f...

The present study was conducted to screen a laccase-producing fungal endophyte, optimize fermentation conditions, and evaluate the decolorization ability of the laccase. A new fungal endophyte capable of laccase-producing was firstly isolated from pigeon pea and identified as Myrothecium verrucaria based on a ITS-rRNA sequences analysis. Meanwhile, various fermentation parameters on the laccase...

Nanometer TiO2 photocatalysts were prepared by the sol–gel method. The catalysts characterized X-ray diffraction, Fourier-transform infrared spectroscopy, ultraviolet-visible and other techniques. Methyl orange solution was used for degradation of organic material ultrasonic technology to determine photocatalytic performance catalysts. results show that Ni-N-TiO2 is clearly improved under condi...

Gadolinium oxide (Gd2O3) nanoparticles were prepared via the reaction of gadolinium nitrate hexahydrate (Gd (NO3)3·6H2O) and ethylamine (C2H5NH2), their surface morphology, particle size, properties examined by using scanning electron microscopy, X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FT-IR) ultraviolet visible (UV-vis) spectroscopy. The Gd2O3 used as photocata...
