Characterizing drivers of microbial community structure and function in diverse marine sediments

Creator:: Graw, Michael F.
Abstract:: Marine sediments are one of the largest habitats for microbial life on earth. These microorganisms play critical roles in biogeochemical cycling both within the subsurface and between the sediment and water columns. However, microbial communities in sediments are highly heterogeneous and the factors defining microbial community structure and metabolic function...

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...

Bacterial community analysis, new exoelectrogen isolation and enhanced performance of microbial electrochemical systems using nano-decorated anodes

Creator:: Xu, Shoutao
Abstract:: Microbial electrochemical systems (MESs) have attracted much research attention in recent years due to their promising applications in renewable energy generation, bioremediation, and wastewater treatment. In a MES, microorganisms interact with electrodes via electrons, catalyzing oxidation and reduction reactions at the anode and the cathode. The bacterial community of a...
Resource Type:: Dissertation
Full Text:: requires an understanding of the ecology in microbial communities of MFCs. Many researchers have

Microbial enhanced oil recovery : a pore-scale investigation of interfacial interactions

Creator:: Armstrong, Ryan T.
Abstract:: Current oil production technologies recover only about one‐third to one‐half of the oil originally present in an oil reservoir. Given current oil prices, even a modest increase in oil recovery efficiency is fiscally attractive. One novel approach to increase oil recovery efficiency is a process called microbial enhanced oil recovery...

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...

Interactions between microbial dynamics, water flow, and solute transport in unsaturated porous media

Creator:: Yarwood, Rockie R.
Abstract:: Bioremediation in the vadose zone is unpredictable because of poor understanding of factors influencing microbial growth in this environment. A lab-scale experimental system was developed to examine, noninvasively, interactions between microbial growth, water flow, and solute transport in unsaturated porous media. Measurements of microbial colonization, and its impact on hydrology,...

An integrative approach to understanding pyoluteorin biosynthesis in the biological control bacterium Pseudomonas fluorescens Pf-5

Creator:: Nowak-Thompson, Brian
Resource Type:: Dissertation
Full Text:: plant physiology has focused on two types of microbial interactions, namely parasitism/predation and

Natural Products Discovery from Unique Microbial Habitats

Creator:: Gallegos, David A.
Abstract:: Marine natural products possess an abundance of diverse chemical scaffolds with unique biological activities. By targeting unusual or unique microbial environments within varying marine ecologies we can continue to discover novel chemistry with potentially new molecular targets. The research presented here is focused on exploring unusual chemical ecologies and the...

Culturing uncultured environmental microorganisms

Creator:: Connon, Stephanie A.
Abstract:: Research on natural environments, over the last decade, is replete with microbial diversity studies that used culture-independent approaches. The cloning and sequencing of the 16S rRNA genes has been the driving force in the expansion of awareness about the great diversity of previously undiscovered microorganisms. Well-known uncultured groups of microorganisms...

Determinants of microbial community structure and substrate utilization potential in soils of vegetable cropping systems

Creator:: Schutter, Mary E.
Abstract:: The Oregon Long-Term Soil Quality Project was initiated to identify soil properties that respond rapidly to alternative management practices. Such practices included winter cover cropping, which was implemented at two experimental research stations and several grower fields throughout the Willamette Valley. The goal of this thesis was to identify the...
