9605069 Parker Description: This award is for the "U.S.-India Cooperative Research: Interaction of Toxic Metals with an Abundant Natural Material, Capsular Polysaccharide from Indian Cyanobacteria". The project is directed by Dorothy Parker, University of Wisconsin and L.C. Rai, Banaras Hindu University. This project will examine the accumulation of toxic metals by cyanobacteria and cyanobacterial polysaccharides from Indian waters. In addition to having unique metal content, many Indian ponds are a biologically-reliable and environmentally-constant source of the cyanobacterium Microcystis which adsorbs specific metal ions. The research will contribute to fundamental knowledge on: cyanobacterial polysaccharides with affinities for toxic or valuable metals; the role of these polysaccharides in the cycling or accumulation of metals in aquatic ecosystems; the range of extracellular polysaccharides produced by cyanobacteria from two continents; and the utility of these polysaccharides in metal- related biotechnology. Scope: This collaboration was initiated by an INT supported planning visit for Dr. Parker, plus a sabbatical visit to Baneras Hindu University. The collaboration which links two university research laboratories expands the capabilities of both groups and makes it possible to examine novel questions that pertain to environmental concerns and biotechnical applications affecting India and the U.S. ***

描述：该奖项授予“美印合作研究：有毒金属与来自印度蓝藻菌的丰富天然物质荚膜多糖的相互作用”。该项目由威斯康星大学的Dorothy Parker和巴纳拉斯印度大学的L.C. Rai指导。该项目将研究来自印度水域的蓝藻和蓝藻多糖对有毒金属的积累。除了具有独特的金属含量，许多印度池塘是一个生物可靠和环境稳定的蓝藻微囊藻的来源，它吸附特定的金属离子。该研究将有助于基本知识：蓝藻多糖与有毒或有价值的金属亲和力；这些多糖在水生生态系统中金属循环或积累中的作用；胞外多糖的范围产生的蓝藻从两个大陆；以及这些多糖在金属相关生物技术中的应用。范围：这次合作是由INT支持的Parker博士计划访问发起的，加上对Baneras印度教大学的休假访问。这项将两所大学的研究实验室联系起来的合作扩大了两个小组的能力，并使研究与影响印度和美国的环境问题和生物技术应用有关的新问题成为可能
