Influence of glucose feeding on the ligninolytic enzyme production of the white-rot fungus Phanerochaete chrysosporium

The present work studied the influence of glucose feeding on the ligninolytic enzyme production of Phanerochaete chrysosporium in a nitrogen-limited (C/N ratio is 56/8.8 mmol/L) medium. Several sets of shaking flask experiments were conducted. The results showed that 2 g/L glucose feeding on the first day of the culture (24 h after the inoculation) simulated both fungal biomass growth and enzyme production. The manganese peroxidase (MnP) activity was 2.5 times greater than that produced in cultures without glucose feeding. Furthermore, the glucose feeding mode in fed-batch culture was also investigated. Compared to cultures with glucose feeding every 48 h, cultures with glucose feeding of 1.5 g/L (final concentration) every 24 h produced more enzymes. The peak and total yield of MnP activity were 2.7 and 3 times greater compared to the contrast culture, respectively, and the enzyme was kept stable for 4 days with an activity of over 200 U/L.

Analysis on sensitivit and landscape ecological spatial structure of site resources

This article establishes a set of indicators and standards for landscape ecological sensitivity analysis of site resources by using the theories and approaches of landscape ecology.It uses landscape diversity index(H),evenness(E),natural degree(N),contrast degree(C) to study spatial structure and landscape heterogeneity of site resources and thus provides a qualitative-quantitative evaluation method for land planning and management of small ,medium scale areas.The analysis of Yantian District,Shenzhen of China showed that Wutong Mountain belonged to high lanscape ecological sensitivity area,Sanzhoutian Reservoir and Shangping Reservoir were medium landscape sensitivity area and high ecological sensitivity area;Dameisha and Xiaomeisha belonged to medium sensitivity area caused by the decline of natural ecological areas.Shatoujiao,Yantian Pier belonged to low sensitivity area but urban landscape ecological development had reshaped and influenced their landscape ecological roles in a great extent.Suggestions on planning,protection goals an development intensity of each site or district were raised.     

四川锦屏山地区部分地层时代、玄武岩和花岗岩地球化学特征及构造环境

锦屏地区的地质研究程度较低，部分地层时代争议较大，玄武岩、花岗岩的性质、物质来源和构造环境等尚未深入研究。为了切实评价区域稳定性，基础地质研究十分重要。通过同位素年代学和孢粉分析，改盐塘组时代由中三叠世为早二叠世，皮罗渡桥西黑色砂页岩层为晚三叠世；稀土元素、过渡元素、微量元素和岩石化学分析表明，在金一箐断裂东西两侧分布的玄武岩为上地幔来源、不同于陆海环境的大陆裂谷喷发产物，花岗岩的分异和重熔程度不同，代表造山期挤压向造山期后拉张环境转化。上述结论为该区构造发展演化和区域稳定性评价、矿产资源寻找提供了重要基础资料。
