Marine Microbial Sulfur Transformations

最近发现的新类型的硫细菌提示了 关于海洋硫循环的想法的修订和 循环中的微生物。 这项研究将集中在 元素硫的还原和氧化转化， 亚硫酸盐、硫代硫酸盐和硫酸盐， 好氧/缺氧界面在黑海，与比较 这些转变的生物与化学性质。 重点 黑海将利用优秀的海洋学 和地球化学背景知识的强氧化/缺氧 界面和缺氧沉积物及底层沃茨。 它还将 促进在这一重要议题上的重要合作。 詹纳斯博士是世界上最优秀的海军陆战队员之一 微生物学家具有良好的生产力和专业记录 基金会的支持。 他已经提供了 在提议的黑海倡议中发挥重要领导作用 多学科研究考察。

Recent discoveries of new types of sulfur bacteria prompt a revision of out thinking on the marine sulfur cycle and the role of microbial agents in cycling. This research will concentrate on the reductive and oxidative transformations of elemental sulfur, sulfite, thiosulfate and sulfate both within and below the oxic/anoxic interface in the Black Sea, with comparisons of biological vs. chemical nature of these transformations. The focus on the Black Sea will take advantage of the excellent oceanographic and geochemical background knowledge on the strong oxic/anoxic interface and the anoxic sediments and bottom waters. It will also facilitate significant collaborations on this important topic. Dr. Jannasch is one of the world's leading marine microbiologists with a strong record of productivity and major discovery with Foundation support. He has already provided significant leadership in the initiation of the proposed Black Sea multidisciplinary research expedition.
