1. Evaluation of Pacific White Shrimp (Litopenaeus vannamei) Health During a Superintensive Aquaculture Growout using NMR-based Metabolomics
Published: 3/27/2013
Authors: Tracey Beth schock Johnston, Daniel W Bearden, Jessica Duke, Abby Goodson, Daryl Weldon, Jeff Brunson, John Leffler
Abstract: Success of the shrimp aquaculture industry requires technological advances that increase production and environmental sustainability. Indoor, superintensive, aquaculture systems have been developed that permit year-round production of farmed shrimp a ...

2. Nanoscale Fullerene Compression of an Yttrium Carbide Cluster
Published: 4/13/2012
Authors: Jianyuan Zhang, Fuhrer Tim, Wujun Fu, Jiechao Ge, Daniel W Bearden, Jerry Dallas, Duchamp James, Kenneth Walker, Hunter Champion, Hugo Azurmendi, Kim Harich, Harry C. Dorn
Abstract: The encapsulation of clusters (or small molecules) in spheroidal fullerene cages provides a unique isolated environment that is important in describing their shape, dynamics, and physical properties. For the case of yttrium carbide clusters, we fin ...

3. Environmental Metabolomics
Published: 3/15/2012
Author: Daniel W Bearden
Abstract: The application of metabolomics in the field of environmental science or ecology, which has developed based substantially on NMR spectroscopic approaches, is a fast paced, rapidly developing field which seems to be poised to help re-frame the discu ...

4. An NMR-based Metabolomic Assessment of Cultured Cobia Health in Response to Dietary Manipulation
Published: 1/8/2012
Authors: Tracey Beth schock Johnston, Sarah Newton, Karl Brenkert, John Leffler, Daniel W Bearden
Abstract: Aquaculture produces a significant source of protein for global human consumption. Commercial fish diets rely heavily on fishmeal and fish oil, which can be costly. Alternative protein and lipid sources may provide nutritionally improved high per ...

5. NMR Analysis of Metabolic Responses to Extreme Growing Conditions of the Temperature-Dependent Coral Pathogen Vibrio coralliilyticus
Published: 12/5/2011
Authors: Arezue Boroujerdi, Stephen S. Jones, Daniel W Bearden
Abstract: Recent metabolomics research on the temperature-dependent coral pathogen Vibrio coralliilyticus has led to the discovery of several compounds produced by the organism as a response to high-density, low nutrient growing conditions. Three compounds ...

6. Characterization of (1-3,1-6)-{beta}-D-Glucan Side Chain Structure Provides the Basis for a New Model of Fungal Cell Wall Rigidity and Flexibility
Published: 11/11/2011
Authors: Daniel W Bearden, Douglas W. Lowman, Lara J. West, Michael F. Wempe, Trevor D. Power, Harry E. Ensley, Ken Haynes, David L. Williams, Michael D. Kruppa
Abstract: Glucan is a (1-3)-{beta}-linked glucose polymer with (1-6)-{beta}-linked side chains and a major component of fungal cell walls. Glucans provide structural integrity to the fungal cell wall. The nature of the (1-6)-{beta}-linked side chain structure ...

7. Biosynthetic origin of the 3-amino-2,5,7,8-tetrahydroxy-10-methylundecanoic acid moiety and absolute configuration of pahayokolides A and B
Published: 6/8/2011
Authors: Li Liu, Daniel W Bearden, Kathleen S. Rein
Abstract: Pahayokolide A is a cyclic undecapeptide from the cyanobacterium Lyngbya sp. The absolute configurations of the amino acids of pahayokolide A have been determined. Pahayokolide A contains the unusual α-hydroxy-β-amino acid, 3-amino-2,5,7, ...

10. NMR-Based Microbial Metabolomics and the Temperature-Dependent Coral Pathogen Vibrio coralliilyticus
Published: 9/18/2009
Authors: Daniel W Bearden, Arezue Boroujerdi, Tracey Beth schock Johnston, Alexander Meyers, Elizabeth C. Pollock, Sara Lien Huynh, Maria Vizcaino, Pamela J Morris
Abstract: Coral bleaching occurs when the symbioses between coral animals and their zooxanthellae is disrupted, either as part of a natural cycle or as the result of unusual events. The bacterium Vibrio coralliilyticus has been linked to coral disease global ...
