9813991ArnostiThis cooperative research award supports Carol Arnosti and a graduate student from the University of North Carolina at Chapel Hill to collaborate with B.B. Jorgensen of the Department of Biogeochemistry at the Max Planck Institute for Marine Microbiology in Bremen, Germany. The focus of the research is the complex community of bacteria responsible for transforming macromolecular organic matter, ultimately reducing it to CO2. The collaboration allows a unique blend of complementary expertise, since the U.S. side has experience in the study of the initial steps of organic matter remineralization and the German group has experience studying the final stages. The rates and pathways of carbon remineralization in marine sediments profoundly affect carbon cycling on local as well as global scales. The composition and dynamics of the diverse group of microbes responsible for remineralization of organic carbon, however, are largely unknown, and the rate-controlling steps in the remineralization process only poorly understood. By focusing on the links between the initial and terminal steps in remineralization, the collaborative project should lead to greater insight into these key steps of the carbon cycle.

Jorgensen合作，在德国巴布雷曼市的Max Planck海洋微生物学研究所。 该研究的重点是负责转化大分子有机物的复杂细菌群落，最终将其降低到二氧化碳。 这项合作允许互补专业知识的独特融合，因为美国方面具有回忆有机物的初始步骤的经验，而德国集团具有研究最后阶段的经验。 海洋沉积物中碳回忆性的碳回忆性的速度和途径对局部和全球尺度上的碳循环产生了深远的影响。 然而，负责回忆有机碳化的多种微生物组的组成和动力学基本上是未知的，并且在回忆过程中的速率控制步骤只有较少的理解。 通过关注回忆起初始步骤和终端步骤之间的联系，该协作项目应更深入地了解碳循环的这些关键步骤。
