  • 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...

  • Prokaryotes associated with marine crust

    Creator:
    Mason, Olivia Underwood
    Abstract:
    Oceanic crust covers nearly 70% of the Earth's surface, of which, the upper, sediment layer is estimated to harbor substantial microbial biomass. Marine crust; however, extends several kilometers beyond this surficial layer, and includes the basalt and gabbro layers. In particular, the basalt layer has high permeabilities which allows for...
