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...

Cloning and biochemical characterization of the hectochlorin biosynthetic gene cluster from the marine cyanobacterium Lyngbya majuscula

Creator:: Ramaswamy, Aishwarya V.
Abstract:: Cyanobacteria are rich in biologically active secondary metabolites, many of which have potential application as anticancer or antimicrobial drugs or as useful probes in cell biology studies. A Jamaican isolate of the marine cyanobacterium, Lyngbya majuscula was the source of a novel antifungal and cytotoxic secondary metabolite, hectochlorin. The structure...

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...

Performance of Oregon derived malolactic bacteria : studies on storage stability and their use in the wine industry

Creator:: Micheals, Nancy J.
Abstract:: Commercial vats of Chardonnay and Pinot Noir were inoculated during yeast fermentation with starter cultures containing 10⁷ - 10⁹ cfu/ml of the malolactic bacteria Leuconostoc oenos Erla and Ey2d in lots ranging from 55 to 4,000 gallons. Chardonnay inoculated with Ey2d completed MLF in an average of 56 days at...

Construction of a model organism for performing calcium carbonate precipitation in a porous media reactor

Creator:: Kaufman, Megan J.
Abstract:: Aquifers are an important storage location and source of fresh groundwater. They may become polluted by a number of contaminants including mobile divalent radionuclides such as strontium-90 which is a byproduct of uranium fission. A method for remediating such divalent radionuclides is sequestration through co-precipitation into calcium carbonate. Calcium carbonate...

Effects of long-term nutrient starvation on a marine psychrophilic vibrio

Creator:: Novitsky, James Alan
Abstract:: Ant-300, a psychrophilic marine vibrio, was starved for periods in excess of one year. Cells starved at a high initial cell density increased in numbers from 100 to 800% of the initial number of cells during the first week. Fifty percent of the population remained viable for six weeks while...

Bacteriophages for Leuconostoc oenos : a survey of Oregon wineries

Creator:: Eschelbach, Matthew Michael
Abstract:: A study of malolactic bacteria of the Leuconostoc genus, especially L. oenos, and their bacteriophages was conducted. A search for the presence of infectious bacteriophages in grapes, musts, and juices employed in malo-lactic fermentation (MLF) was conducted; no evidence, either physical or biological, was found for the existence of these...
