Chloroflexi CL500-11 Populations That Predominate Deep-Lake Hypolimnion Bacterioplankton Rely on Nitrogen-Rich Dissolved Organic Matter Metabolism and C₁ Compound Oxidation

Creator:: Denef, Vincent J., Mueller, Ryan S., Chiang, Edna, Liebig, James R., and Vanderploeg, Henry A.
Abstract:: The Chloroflexi CL500-11 clade contributes a large proportion of the bacterial biomass in the oxygenated hypolimnia of deep lakes worldwide, including the world's largest freshwater system, the Laurentian Great Lakes. Traits that allow CL500-11 to thrive and its biogeochemical role in these environments are currently unknown. Here, we found that...

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...

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...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

Creator:: Baker, Kristina D.
Abstract:: The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...

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...

Anaerobic Co-Digestion of Municipal Sludge and Fats, Oils, and Greases: Effects on Digester Performance and Microbial Community Dynamics

Creator:: Berninghaus, Ashley E.
Abstract:: The natural production of methane via anaerobic digestion (AD) is facilitated by a complex community of microorganisms, primarily bacteria and archaea, referred to as the AD microbiome. AD is growing in prominence as a solution to the disposal of food waste, sewage sludge, and the organic fraction of municipal solid...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

Biogeochemical Processing of Freshwater Carbon in the Anthropocene

Creator:: Buser, Jessica Z.
Abstract:: Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...
