  • Single-Cell Genomics of Uncultivated Marine Bacteria

    Creator:
    Landry, Zachary
    Abstract:
    Historically, the difficulty of obtaining pure cultures of abundant marine microbial plankton has an obstacle to reconstructing the underlying mechanisms of biogeochemistry in the ocean. While a number of dominant marine species from the ocean surface have been cultured, the dominant microbial plankton of the dark ocean proved far more...

  • Marine bacterioplankton abundances and distributions

    Creator:
    Morris, Robert M.
    Abstract:
    Microorganisms play key roles in ocean biogeochemistry. However, several predominant groups of uncultured bacterioplankton thought to contribute to important biogeochemical processes in the oceans are known primarily from gene cloning studies. Although these studies have greatly expanded our view of microbial diversity in the oceans, they are not quantitative and...

  • 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...

  • Genomic-assisted determination of the natural nutrient requirements of the cosmopolitan marine bacterium 'Candidatus Pelagibacter ubique'

    Creator:
    Tripp, H. James
    Abstract:
    To identify factors limiting 'Candidatus Pelagibacter ubique' maximum cell density and growth rate in pure culture on seawater, the genome sequence of 'Cand. P. ubique' was analyzed, culturing experiments with organic and inorganic nutrient additions were made, and radiotracer uptake experiments were performed. The genome was sequenced, custom data mining...
