0225983 Zinder描述：该奖项是为了支持纽约康奈尔大学微生物学系Stephen Zinder博士和埃及科学家团队之间的合作项目，该团队包括埃及亚历山大穆巴拉克市科学研究和技术应用的Hany Hussein博士，Ahmed Gaballa博士和Yasser Abd Elfattah博士。 本研究的主要目的是分离最有效的微生物培养能够产生生物乳化剂。 研究人员还计划通过研究不同的环境条件和评估不同的碳和氮限制对表面活性剂生产率的影响来研究优化生产工艺的方法。研究人员将从生态系统中分离出能够产生可生物降解表面活性剂的最有效的微生物培养物。 将从埃及不同地区收集样品，并将分离和表征能够产生生物表面活性剂的微生物。他们还计划研究使用这些优化的生产工艺来大规模生产生物表面活性剂。预计发酵过程将在提高生物表面活性剂生产的整体过程的经济性方面发挥关键作用。范围：表面活性剂是表面活性化合物，能够降低液体、固体和气体之间界面的表面张力和界面张力，从而使它们能够在水或其他液体中容易地混合或分散为乳液。 生物表面活性剂的主题与埃及高度相关，因为埃及将环境的可持续性作为高度优先事项。 发现产生表面活性剂的微生物将对社会和环境产生非常理想的影响。 提出了一些实验，要求在广泛的领域的专业知识。 Zinder，Hussein，Gaballa和Abdel Fattah博士拥有这项研究所需的学科经验。该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

0225983ZinderDescription: This award is to support a collaborative project between Dr. Stephen Zinder, Department of Microbiology at Cornell University, Ithaca, New York and a team of Egyptian scientists that includes Dr. Hany Hussein, Dr. Ahmed Gaballa, and Dr. Yasser Abd Elfattah, of Mubarak City for Scientific Research and Technology Applications in Alexandria, Egypt. The main objective of this research is to isolate the most potent microbial cultures capable of producing bioemulsifier. The investigators plan also to study methods for optimization of the production process through the study of the different environmental conditions and by assessing the influence of different carbon and nitrogen limitations on surfactant productivity. The investigators will isolate the most potent microbial cultures capable of producing biodegradable surfactants from the ecosystem. Samples will be collected from different parts of Egypt and the microbes capable of producing biosurfactants will be isolated and characterized. They also plan to examine the use of these optimized production processes to produce the biosurfactant on a large scale. It is expected that a fermentation process will have a key role in improving the economics of the overall process in biosurfactant production.Scope: Surfactants are surface-active compounds capable of reducing surface and interfacial tension at the interface between liquids, solids and gases, thereby allowing them to mix or disperse readily as emulsions in water or other liquids. The topic of biosurfactants is highly relevant to Egypt where sustaining the environment is a high priority. Discovering microbes that produce surfactants would have a very desirable impact on society and on the environment. A number of experiments are proposed, calling for expertise over a wide area. Drs. Zinder, Hussein, Gaballa and Abdel Fattah have the disciplinary experiences needed for this research. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
