US-Peru Cooperative Research:Bioconversion of Lignocelluloseto Animal Feed by Solid Substrate Fermentation and Ensiling

该奖项支持由科罗拉多州立大学的Robert Tengerdy和秘鲁利马国立农业大学的Marcel Gutierrez-Correa在纤维素生物转化微生物学方面的合作研究。目标是发展农业残留物的生物转化和利用技术，使其成为可消化的富含蛋白质的动物饲料。用木质纤维素降解真菌进行固体底物发酵，然后在存在木质纤维素酶的情况下进行青贮，将低等级的农场残留物转化为高度可消化的富含蛋白质的饲料，保存良好，可长期稳定储存。这项技术在秘鲁和其他欠发达国家的农场使用将带来技术和经济效益，有助于实现发展中国家科学项目的目标。一名秘鲁学生将在科罗拉多州接受培训，并在秘鲁本土的各种基质上对该工艺进行测试。本研究使用的乳酸菌是近年来相关研究中分离到的一种新乳酸菌。这项工作代表了科罗拉多州立大学一个强大的生物技术亲和小组与利马国立农业大学固体底物发酵方面的生物学家和微生物学家专家之间的合作。

This award supports cooperative research in the microbiology of cellulose bioconversion to be conducted by Robert Tengerdy of Colorado State University and Marcel Gutierrez-Correa of the National Agrarian University in Lima, Peru. The goal is the development of the technology of bioconversion and utilization of agricultural residues into digestible, protein enriched animal feed. Solid substrate fermentation with lignocellulose degrading fungi, followed by ensilage in the presence of lignocellulase enzymes converts low grade farm residues into highly digestible, protein rich feed, well preserved for stable long-term storage. The availability of this technology for on-farm use in Peru and other less well developed countries will bring technical and economic benefits which help fulfill the goals of the Science in Developing Countries program. A Peruvian student will be trained in Colorado and the process tested on various substrates indigenous to Peru. The lactobacillus used in this work is a new one isolated in recent related research. This work represents a cooperation between a strong biotechnology affinity group at Colorado State and biologists and microbiologists expert in solid substrate fermentation at the National Agrarian University in Lima.
