0332136 McMahon A broad objective of the proposed work is to determine how microbialcommunity structure and function is linked to successful EBPR process performance. To achieve this objective, the key organisms whose presence is necessary for efficient EBPR operation must be studied. In particular, it is necessary to investigate how these organisms regulate and control the genes and gene products involved in EBPR metabolism. Specific goals of this work are to:oClone the genes involved in PHA and glycogen cycling directly from mixedcommunities in PAO-enriched sludges;oElucidate the mechanisms by which carbon and P cycling occurs in PAOs;oDevelop an immunochemical method to detect polyP metabolism in sludge;oIntegrate observations and recommend potential control strategies for full-scaleEPBR systems.

0332136 McMahon 拟议工作的一个广泛目标是确定微生物群落结构和功能如何与成功的EBPR过程性能相关联。为了实现这一目标，关键的生物体的存在是必要的有效EBPR操作必须进行研究。特别是，有必要研究这些生物体如何调节和控制参与EBPR代谢的基因和基因产物。本研究的具体目标是：直接从富含聚磷菌的混合污泥中克隆与PHA和糖原循环有关的基因;阐明聚磷菌中碳和磷循环发生的机制;开发一种检测污泥中聚磷代谢的免疫化学方法;整合观察结果并为全规模EPBR系统推荐潜在的控制策略。
