Marine Microbial Sulfur Transformations

最近发现的新型硫磺细菌促使人们对海洋硫磺循环和微生物制剂在循环中的作用进行了修订。这项研究将集中于元素硫、亚硫酸盐、硫代硫酸盐和硫酸盐在黑海氧/缺氧界面内和之下的还原和氧化转化，并比较这些转化的生物和化学性质。对黑海的关注将利用关于强烈的缺氧/缺氧界面以及缺氧沉积物和底层水域的出色的海洋和地球化学背景知识。它还将促进在这一重要主题上的重大合作。Jannasch博士是世界领先的海洋微生物学家之一，在基金会的支持下，他在生产力和重大发现方面有着良好的记录。他已经在发起拟议的黑海多学科研究考察队方面发挥了重要领导作用。

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.
