Production of laccase by Coriolus versicolor and its application in decolorization of dyestuffs: (Ⅱ) Decolorization of dyes by laccase containing fermentation broth with or without self-immobilized mycelia

The capability of decolorization for commercial dyes by Coriolus versicolur fermentation broth containing laccase with or without immobilized mycelium was evaluated.With cell-free fermentation broth containing laccase,high decolorization ratio was achieved for acid orange 7,but not for the other dyes concerned.The immobilized mycelium was proved to be more efficient than the cell-free system.All the four dyestuffs studied were found being decolourized with certain extent by immobilized mycelium.The repeated-batch decolorization was carried out with satisfactory results.The experimental data showed that the continuous decolorization of wastewater from a printing and dyeing industry was possible by using self-immobilized C.Versicolor.     

The effect of heating temperature of thin film transistor-liquid crystal display (TFT-LCD) optical waste glass as a partial substitute partial for clay in eco-brick

In order to fulfill the current WEEE directives, the traditional approach to manage thin film transistor-liquid crystal display (TFT-LCD) waste glass is inadequate. It is a serious opportunity to achieve resource conservation, reduction, stabilization and safety of management of TFT-LCD in the near future. To assist in achieving these goals, this study investigated the sintering characteristics and material properties of TFT-LCD waste glass, which can be pulverized and ground and subsequently blended with clay, at various substitution levels (0–40%) and finally fired from 800 °C to 1000 °C to make eco-brick. The brick thus produced was analyzed to determine variations in weight losses on ignition, 24-h absorption, bulk density, shrinkage, compressive strength and microstructure changes. The results for specific gravity, water adsorption, and compressive strength revealed that bricks made from mixtures containing TFT-LCD waste glass met the general requirements for bricks. The advantages of less water absorption, less weight loss on ignition, and a gain in compressive strength in the clay-TFT-LCD waste glass bricks should encourage the use of TFT-LCD waste glass as a brick additive.
