硫是活细胞的必需元素。硫以+ 2 至− 6 的氧化态存在，具有高反应性，原核生物不仅利用硫来构建细胞成分，而且还用于能量转化。近年来，基础研究揭示了越来越多的有关原核反应、参与硫转化的蛋白质和基因的信息。关于硫代谢涉及的酶系统、硫代谢细菌和古细菌的基因组学和蛋白质组学，以及原核生物氧化和还原硫化合物的生态学，新的见解正在出现。此外，已经开发出新方法并应用于研究微生物硫代谢。为了总结近年来的快速发展，交流知识并讨论未来的发展和研究需求，“微生物硫代谢国际研讨会”于2006年6月29日至7月2日在德国明斯特举行。这次研讨会汇集了来自16个国家的85名科学家，继1982年在伦敦举行的细菌硫代谢会议之后，我们认为这次研讨会非常及时。 明斯特的研究重点是原核生物硫能量代谢、所涉及酶的生物化学、此类酶系统的分子遗传学以及含有硫代谢原核生物的生态系统。编制了不同生理群体中存在的硫代谢途径。一系列特邀讲座介绍了生物化学、生态学、蛋白质组学、基因组学以及化能和光养硫氧化细菌、厌氧硫酸盐还原细菌和超嗜热硫代谢古菌的进化方面的最新进展。研讨会的设置和时间安排鼓励年轻科学家和知名科学家之间的非正式讨论和交流。本会议集以23场特邀报告为代表，介绍和报告了各个领域的前沿研究，展现了研讨会的精髓。作者的努力编写了一本书籍，汇编了光养和化能细菌和古细菌中硫代谢的最新技术。本书按照研讨会的七大主题组织：(1)硫酸盐还原菌、(2)硫代谢原核生物的基因组学/蛋白质组学、(3)硫化合物氧化的生物化学、(4)有机硫化合物的代谢、(5)古细菌的异化硫代谢、(6)生态学 (七)具体方法及应用方面。
Sulfur is an essential element for the living cell. Sulfur occurs in oxidation states of+ 2 to− 6, is highly reactive and is used by prokaryotes not only to build up cell constituents but also for energy transformation. Basic research has revealed in recent years an increasing rate of information on prokaryotic reactions, proteins and genes involved in sulfur transformations. New insights are emerging concerning enzyme systems involved in sulfur metabolism, genomics and proteomics of sulfurmetabolizing bacteria and archaea, and the ecology of prokaryotes oxidizing and reducing sulfur compounds. Furthermore, new methods have been developed and are being applied to study microbial sulfur metabolism. To summarize the fast-moving developments of recent years, to exchange knowledge and to discuss future developments and research needs, the “International Symposium on Microbial Sulfur Metabolism” was held in Münster, Germany, from 29 June to 2 July 2006. This symposium brought together 85 scientists from 16 countries and was felt to be timely after a previous meeting on bacterial sulfur metabolism which took place in London in 1982. The symposium in Münster focused on prokaryotic sulfur energy metabolism, the biochemistry of the enzymes involved, the molecular genetics of such enzyme systems as well as on the ecosystems harboring sulfur-metabolizing prokaryotes. Pathways of sulfur metabolism present in different physiological groups were compiled. A collection of invited lectures presented the state of the art regarding biochemistry, ecology, proteomics, genomics and evolution of chemotrophic and phototrophic sulfur-oxidizing bacteria, anaerobic sulfate-reducing bacteria and hyperthermophilic sulfur-metabolizing archaea. The symposium setting and time schedule encouraged informal discussion and exchange between young and established scientists.This proceedings volume presents the essence of the symposium represented by 23 invited lectures which introduce and report cutting-edge research in the various fields. The efforts of the authors have created a book which compiles the state of the art on sulfur metabolism in phototrophic and chemotrophic bacteria and archaea. The book is organized according to the seven major topics of the symposium:(1) sulfate-reducing bacteria,(2) genomics/proteomics of sulfurmetabolizing prokaryotes,(3) biochemistry of sulfur-compound oxidation,(4) metabolism of organosulfur compounds,(5) dissimilatory sulfur metabolism in archaea,(6) ecology of sulfur bacteria and (7) specific methods and applied aspects.
