发展中国家科学奖将 支持T.肯特柯克 威斯康星州大学和拉斐尔维库纳的 智利天主教大学。 项目 旨在将真菌研究引入智利 研究者的实验室，并描述 木质素降解酶系的研究 来自智利和美国的降解真菌 通过这个项目，智利科学家将学习 生理、生物化学和遗传学技术 丝状真菌的研究。 他的意志将成为 智利第一家拥有专业知识的实验室， 高等丝状真菌的分子遗传学， 是为数不多的研究这些真菌的科学家之一， 容量 一种美国的和两种智利的木质素 将研究降解真菌。 它们产生的酶 将被识别和表征。 条件 最佳的酶生产和高效的木质素 将确定矿化度。 调查人员的 过去的合作表明，细菌只发挥 对聚合木质素作用较小。 因此，智利 研究人员现在的目标是专注于真菌。 的 木质素分解真菌具有很大的潜力， 在智利和美国的实际应用，特别 用于造纸制浆工业。 美国及 智利方面将从基本信息中受益 由他们的研究产生。

This Science in Developing Countries award will support the research collaboration of T. Kent Kirk of the University of Wisconsin and Rafael Vicuna of the Pontificia Universidad Catolica de Chile. The project aims to introduce fungal research into the Chilean investigator's laboratory, and to characterize the lignin-degrading enzyme system of unusual lignin- degrading fungi from Chile and the U.S. Through this project, the Chilean scientist will learn techniques for physiological, biochemical, and genetic studies with filamentous fungi. His will become the first laboratory in Chile with expertise in the molecular genetics of higher filamentous fungi, and one of the few working with these fungi in any capacity. One U.S. and two Chilean strains of lignin- degrading fungi will be studied. Enzymes they produce will be identified and characterized. Conditions for optimal enzyme production and efficient lignin mineralization will be determined. The investigators' past collaboration has shown that bacteria exert only minor action on polymeric lignin. Thus, the Chilean researcher now aims to focus on fungi. The ligninolytic fungi have substantial potential for practical applications in Chile and U.S., particularly for the paper pulping industry. Both the U.S. and Chilean sides will benefit from the basic information generated by their research.
