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...

Proteomic analyses of marine bacteria

Creator:: Sowell, Sarah M.
Abstract:: Proteins are the metabolic machines of the cell and as such, the study of proteins could illuminate the dominant biological activities that are occurring within cells and reveal how an organism interacts with its environment. Here, we used proteomic techniques to study the abundant marine bacterium SAR11 both as an...

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...

Bacterioplankton in the Oregon upwelling system: distribution, cell-specific leucine incorporation, and diversity

Creator:: Longnecker, Krista
Abstract:: Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...

The proteomic and transcriptomic responses to iron, sulfur, and nitrogen limitation in the abundant marine bacterium Candidatus Pelagibacter ubique

Creator:: Smith, Daniel P.
Abstract:: Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...

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...

Diversity of bacterioplankton and plastid SSU rRNA genes from the eastern and western continental shelves of the United States

Creator:: Rappé, Michael Stephen
Abstract:: The phylogenetic diversity of two continental shelf picoplankton communities was examined by analyzing SSU (16S) ribosomal RNA (rRNA) genes amplified from environmental DNA with bacterial-specific primers and the polymerase chain reaction (PCR). Picoplankton populations collected from the pycnocline (10 m) over the eastern continental shelf of the United States near...
