  • Conserved properties in the metagenome of a large bacterioplankton population

    Creator:
    Wilhelm, Larry John
    Abstract:
    Candidatus Pelagibacter ubique is the first cultured representative of the SAR11 clade, a clade that is found throughout the oceans and accounts for approximately 25% of all bacterial cells [1]. It has a streamlined genome that is the smallest of any known free-living organism. In this study the complete genome...

  • 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...

  • 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...

  • Development and application of genomic DNA based methods for the identification and characterization of marine bacterioplankton

    Creator:
    Lanoil, Brian D.
    Abstract:
    A series of experiments was performed to determine the feasibility of genomic DNA-based methods for ecological and physiological studies of dominant bacteria from complex natural systems. Two approaches, bacterial chromosomal painting (BCP) and environmental genomics (EG), were evaluated for the potential to identify and enumerate specific bacterial groups in situ...
