  • Remineralization of marine particulate organic matter

    Creator:
    Burkhardt, Brian Gary
    Abstract:
    Marine microorganisms play a significant role in the cycling of nutrients in the open ocean through production, consumption, and degradation of organic matter (OM). Carbon (C), nitrogen (N), and phosphorus (P) are essential ingredients in every known recipe for life. However, the cycling of each of these elements proceeds at...

  • Metabolism of one carbon (C1) and methylated compounds in SAR11 bacteria

    Creator:
    Sun, Jing
    Abstract:
    SAR11 Alphaproteobacteria are the most abundant aerobic chemoheterotrophs in ocean surface waters. Previous studies have indicated SAR11 cells play an important role in marine carbon cycling and consume up to half of some common dissolved organic compounds, such as amino acids. During sequencing of the first SAR11 genome, genes for...
