BIOGEOCHEMICAL SIGNIFICANCE OF BACTERIA-ORGANIC-MATTER INTERACTIONS IN THE OCEAN
Current models of oceanic carbon biogeochemistry include organic matter utilization by bacteria as a significant carbon flux pathway. An emergent view is that important biogeochemical roles of bacteria might be missed by the current emphasis on cumulative carbon demand of bacteria. Bacterial modification of organic matter (e.g., via ectohydrolytic activity) can critically modify the biogeochemical behavior of organic matter, and in some instances, that of the associated inorganic materials as well. I will discuss how the biogeochemical consequences of such "modification
interactions" might be conceptualized, studied and incorporated into models of oceanic carbon biogeochemistry.
