A Microscopic Study of Paper Decayed by <Emphasis Type="Italic">Trichoderma harzianum</Emphasis> and <Emphasis Type="Italic">Paecilomyces variotii</Emphasis>

The current study is interested in evaluating the decay of cotton, Whatman and chemical pulp caused by Trichoderma harzianum and Paecilomyces variotii. The structural changes of the paper were evaluated by Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). The SEM results show differences in hyphae colonization and paper decay patterns between studied species under the current study; P. variotii caused an eroded structure in the cotton (cavity forming), whereas the initial T. harzianum colonization produced rupture and erosion (soft-rot decay type II) for the three types of paper ,the gaps were elongated with sharp pointed ends, which consisted either of individual cavities or in chains. Moreover, FTIR results confirmed that there a relationship could be observed between fungal decay and crystalline cellulose content because the intensity of peaks at 1335 and 1111 cm^?1 significantly decreased due to the fungal decay. Furthermore, the intensity of O–H stretching absorption slightly decreased, and this may be attributed to hydrolysis of cellulose molecules.     

基于GIS与栅格数据的安徽省人居环境自然适宜性测评

科学度量人居环境自然背景的适宜性，有助于合理引导人口分布与流动，促进区域人口、资源环境协调发展。运用GIS技术，以250 m×250 m栅格为基本单元，选取气候、地形、水文、地被、自然灾害等因子，构建人居环境自然适宜性评价模型，定量测评安徽省人居环境自然适宜程度，剖析各类型区的适宜性和限制性。研究表明：安徽省人居环境指数介于33.64～74.58之间，人居环境自然适宜性总体较好，绝大部分地区适宜人类居住，适宜性在空间上大体呈现南高北低的态势，与现有人口分布格局相反。一般适宜区面积最广，占安徽省总面积的46.08%；比较适宜区次之，占31.29%；高度适宜区占22.54%；临界适宜区面积最小，仅占0.08%。安徽省近61.16%的人口分布在一般适宜区，高度适宜区与比较适宜区人口所占比例不足40%，临界适宜区人口极为稀少。地形起伏度和水文指数是造成全省人居环境自然适宜性分异的主要因子，测评结果较为客观地反映了安徽省人居环境的自然本底。全省人口生存与发展的空间较大，人口流动与集聚的适宜范围较广。 关键词： 人居环境；自然适宜性；栅格；GIS；安徽省     

连续流双室微生物燃料电池处理工业废水

以实际中药废水作为阳极基质、实际含镉废水作为阴极电解液,构建了连续流双室微生物燃料电池(MFC),考察了其产电性能及对两种废水的处理效果。78 d的运行数据表明:系统可实现最大输出电压417mV、最大体积功率密度11.8 W/m3,最大体积功率密度运行条件下的库伦效率为18.5%;在阳极进水有机物浓度变化较大的情况下,实现了阳极对中药废水中有机物的有效去除,平均COD去除率为81.5%;阴极对含镉废水中Cd2+的去除率为79.4%～84.8%。这表明MFC同步处理中药废水及重金属废水具有一定的可行性。
