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.

洞庭湖区湿地资源可持续利用途径研究

湿地具有特殊的生态功能和社会经济价值。洞庭湖区湿地垦殖强度大,造成了生态环境严重退化的恶果。研究表明:控制人口总量,退田还湖,建立湿地自然保护区,大力发展避洪耐涝型湿地特色产业是保护和合理利用湿地资源的有效途径,且已取得了良好的社会、经济、生态效益。由此认为,如何协调好人口、资源与环境的关系是实现湿地资源可持续利用的战略目标。
