Raskin 9410476 This is an award to provide support for research on the causes and control of foaming in aerobic and anaerobic, suspended growth bioreactors. The investigator plans on designing oligonucleotide rRNA-targeted probes that are specific for identifying several foam-causing microorganisms. The probes will be used to study and characterize the conditions that lead to foaming and the microbiological flora associated with foaming in bioreactors that are used in waste treatment processes. Foaming is a problem commonly associated with bioreactors used in wastewater treatment processes and in the processing of residuals produced during the treatment process. The foaming problem is frequently associated with conditions that result in dominance by filamentous microorganisms in the reactors. Results of this research are expected to provide new insights into the causes of foaming and the potential for its control. This knowledge is expected to be applied in improving the operation of existing bioreactors and in improving the engineering design of systems utilizing bioreactors. The proposal leading to this award was submitted in accord with NSF 92-122, Research Initiation Awards Program. ***

Raskin 9410476 该奖项旨在为需氧和厌氧悬浮生长生物反应器中泡沫的成因和控制研究提供支持。研究人员计划设计寡核苷酸 rRNA 靶向探针，专门用于识别几种引起泡沫的微生物。 这些探针将用于研究和表征废物处理过程中使用的生物反应器中导致泡沫产生的条件以及与泡沫相关的微生物菌群。 起泡是废水处理过程中使用的生物反应器以及处理过程中产生的残留物处理中常见的问题。 起泡问题通常与导致反应器中丝状微生物占主导地位的条件有关。 这项研究的结果预计将为泡沫的原因及其控制潜力提供新的见解。 这些知识预计将应用于改进现有生物反应器的操作以及改进利用生物反应器的系统的工程设计。 获得该奖项的提案是根据 NSF 92-122“研究启动奖励计划”提交的。 ***
