US-Egypt Cooperative Research: Environmentally Friendly Technology for Production and Modification of Cellulose Products

0209877 Gobran描述：该奖项旨在表彰宾夕法尼亚州费城德雷克塞尔大学材料工程系的Riad Gobran博士和埃及开罗国家研究中心纤维素和造纸系的Houssni El-Saied博士对合作项目的支持。 从细菌（木醋杆菌）生产纤维素被认为是满足环境法规的最有益的发展之一。 该项目的目的是研究细菌在实验室和中试工厂规模上生产纤维素产品的潜力。该项目还将探索通过使用纤维素生产的初期阶段的细菌来生产纤维素衍生物。 进一步降低生产成本和污染物质也将通过应用某些农业工业废物，包括糖蜜副产物和稻草和甘蔗渣制浆的黑液，作为生产细菌纤维素（BC）的培养基进行研究。研究范围：造纸和纤维素工业废水，特别是稻草、甘蔗渣等非木质纤维原料产生的废水，对环境造成严重污染。使用新技术或重新设计产品将有助于满足新的环境标准并减少这种污染。 该项目由国际科学和工程办公室以及生物工程和环境系统司资助。

0209877GobranDescription: This award is for support of a cooperative project by Dr. Riad Gobran, Department of Materials Engineering, Drexel University, Philadelphia, Pennsylvania and Dr. Houssni El-Saied, Cellulose and Paper Department, The National Research Center, Cairo, Egypt. Production of cellulose from bacteria (Acetobacter xylinum) is considered as one of the most beneficial developments in meeting environment regulations. The objective of this proposed project is to investigate the potential of the bacteria for the production of cellulose products, on both laboratory and pilot plant scale. This project is also to explore the production of cellulose derivatives by using bacteria from the nascent stage of cellulose production. Further reduction of the production cost and pollutant materials will be also investigated by applying certain agro-industrial wastes, including molasses by-product and black liquors of rice straw and sugar cane bagasse pulping, as cultivation medium for production of bacterial cellulose (BC). The applications of the produced BC in preparation of cellulose derivatives, high quality paper, and in health food industries will be studied.Scope: There is a great amount of pollution caused by paper and cellulose industry effluents, especially those produced from non-wood fibrous materials, e.g. rice straw and sugar cane bagasse. Using new technologies or redesign of products will help meet new environmental criteria and reduce this pollution. This project is funded by the Office of International Science and Engineering and the Division of Bioengineering and Environmental Systems.
