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...

Characterization of novel marine oligotrophic bacteria isolated from the Pacific Ocean : description of Marinivirgula fluito gen. nov., sp. nov., Marinivirgula obesa gen. nov., sp. nov. and Litincola parvulus gen. nov., sp. nov.

Creator:: Shin, Eun Jung
Abstract:: A new high-throughput culturing (HTC) method using a low nutrient heterotrophic medium (LNHM) has led to the isolation of many novel strains of oligotrophic bacteria from marine ecosystems. Four strains belonging to a single dade, HTCC2151, HTCC218OT, HTCC2178T and HTCC2188T, were isolated from the coast of Oregon by the HTC...

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...

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...

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...

Outliers: The Unusual Characteristics of Marine Carbon-Oxidizing Bacterial Cells Adapted to Oligotrophic Conditions

Creator:: Noell, Stephen E.
Abstract:: Oligotrophic bacteria are adapted to low nutrient concentrations. As most of the ocean is oligotrophic (low in nutrients), oligotrophic bacteria thrive in the ocean and make up the majority of planktonic cells. Because of this, oligotrophs are crucial to oceanic nutrient cycles. However, marine oligotrophic bacteria are dwarfed by their...

Disturbances in a marine bacterioplankton system drive community assembly towards niche-based processes

Creator:: Vergin, Kevin L.
Abstract:: Over 100 monthly bacterioplankton DNA samples, from each of the surface and 200 m depths at the Bermuda Atlantic Time-series Study (BATS) site, were analyzed for community assembly processes. Correlation networks, filtered for potential autocorrelation artifacts, were constructed for each depth. Network characteristics for the two depths were remarkably similar...

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...

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...
