Insights Into The Biotechnology Potential Of Methanosarcina, Sean Carr, Nicole R. Buan
Insights Into The Biotechnology Potential Of Methanosarcina, Sean Carr, Nicole R. Buan
Department of Biochemistry: Faculty Publications
Methanogens are anaerobic archaea which conserve energy by producing methane. Found in nearly every anaerobic environment on earth, methanogens serve important roles in ecology as key organisms of the global carbon cycle, and in industry as a source of renewable biofuels. Environmentally, methanogenic archaea play an essential role in the reintroducing unavailable carbon to the carbon cycle by anaerobically converting low-energy, terminal metabolic degradation products such as one and two-carbon molecules into methane which then returns to the aerobic portion of the carbon cycle. In industry, methanogens are commonly used as an inexpensive source of renewable biofuels as well as …
Methanogen Metabolic Flexibility, Sean Carr
Methanogen Metabolic Flexibility, Sean Carr
School of Biological Sciences: Dissertations, Theses, and Student Research
Methanogens are obligately anaerobic archaea which produce methane as a byproduct of their respiration. They are found across a wide diversity of environments and play an important role in cycling carbon in anaerobic spaces and the removal of harmful fermentation byproducts which would otherwise inhibit other organisms. Methanogens subsist on low-energy substrates which requires them to utilize a highly efficient central metabolism which greatly favors respiratory byproducts over biomass. This metabolic strategy creates high substrate:product conversion ratios which is industrially relevant for the production of biomethane, but may also allow for the production of value-added commodities. Particularly of interest are …

Metabolic extremes provide opportunities to understand enzymatic and metabolic plasticity and biotechnological tools for novel biomaterial production. We discovered that seed oils of many Thunbergia species contain up to 92% of the unusual monounsaturated petroselinic acid (18:1Δ6), one of the highest reported levels for a single fatty acid in plants. Supporting the biosynthetic origin of petroselinic acid, we identified a Δ6-stearoyl-acyl carrier protein (18:0-ACP) desaturase from Thunbergia laurifolia, closely related to a previously identified Δ6-palmitoyl-ACP desaturase that produces sapienic acid (16:1Δ6)- rich oils in Thunbergia alata seeds. Guided by a T. laurifolia desaturase crystal structure obtained in this study, …

Biomaterial Substrate Modifications That Influence Cell-Material Interactions To Prime Cellular Responses To Nonviral Gene Delivery, Amy Mantz, Angela K. Pannier
Biomaterial Substrate Modifications That Influence Cell-Material Interactions To Prime Cellular Responses To Nonviral Gene Delivery, Amy Mantz, Angela K. Pannier
Department of Biological Systems Engineering: Papers and Publications
Gene delivery is the transfer of exogenous genetic material into somatic cells to modify their gene expression, with applications including tissue engineering, regenerative medicine, sensors and diagnostics, and gene therapy. Viral vectors are considered the most effective system to deliver nucleic acids, yet safety concerns and many other disadvantages have resulted in investigations into an alternative option, i.e. nonviral gene delivery. Chemical nonviral gene delivery is typically accomplished by electrostatically complexing cationic lipids or polymers with negatively charged nucleic acids. Unfortunately, nonviral gene delivery suffers from low efficiency due to barriers that impede transfection success, including intracellular processes such as …

Extreme Weather, Biotechnology, And Corn Productivity, Jonathan R. Mcfadden, John A. Miranowski
Extreme Weather, Biotechnology, And Corn Productivity, Jonathan R. Mcfadden, John A. Miranowski
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
U.S. agriculture has made impressive strides over the past 50 years in crop yield and input productivity growth, especially since the advent of genetically modified crops in 1996. However, future growth rates could decline if U.S. agriculture does not sufficiently adapt to climate change. We examine the magnitudes of weather impacts on U.S. corn yields during 1960–2011—with a focus on intense precipitation and nitrogen use efficiency—and use the empirical results to forecast yields for the subsequent 20 years (2012-2031). We improve upon past methodologies by employing dynamic Bayesian regressions. These dynamic models permit rapid updating of new information, consistent with …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Peanut allergy is an IgE-mediated adverse reaction to a subset of proteins found in peanuts. Immunotherapy aims to desensitize allergic patients through repeated and escalating exposures for several months to years using extracts or flours. The complex mix of proteins and variability between preparations complicates immunotherapy studies. Moreover, peanut immunotherapy is associated with frequent negative side effects and patients are often at risk of allergic reactions once immunotherapy is discontinued. Allergen-specific approaches using recombinant proteins are an attractive alternative because they allow more precise dosing and the opportunity to engineer proteins with improved safety profiles. We tested whether Ara h …

Department of Sociology: Faculty Publications
Public awareness and utilization of assisted reproductive technology has been increasing, but little is known about changes in ethical concerns over time. The National Survey of Fertility Barriers, a national, probability-based sample of US women, asked 2031 women the same set of questions about ethical concerns regarding six reproductive technologies on two separate occasions approximately 3 years apart. At Wave 1 (2004–2007), women had more concerns about treatments entailing the involvement of a third party than about treatments that did not. Ethical concerns declined between Wave 1 and Wave 2, but they declined faster for treatments entailing the involvement of …

Department of Agronomy and Horticulture: Faculty Publications
Over the past decade genomics resources available for sorghum have rapidly expanded (Paterson Int J Plant Genomics 2008:6, 2008), these resources, coupled with the recent completion of the genome sequence which is relatively small in size (730 Mb) (Paterson et al. Nature 457:551–556, 2009) makes sorghum a rather attractive species to study. Moreover, the USDA germplasm system maintains 42,614 accessions, of which more than 800 exotic landraces have been converted to day length-insensitive lines to facilitate their use in breeding programs. In addition, a set of EMS mutation stocks developed by the USDA Plant Stress and Germplasm Development Unit in …

Stability Of Iaa And Iba In Nutrient Medium To Several Tissue Culture Procedures, Scott Nissen, Ellen Sutter
Stability Of Iaa And Iba In Nutrient Medium To Several Tissue Culture Procedures, Scott Nissen, Ellen Sutter
Department of Agronomy and Horticulture: Faculty Publications
The relative stabilities of IAA and IBA under various tissue culture procedures were determined. IBA was significantly more stable than IAA to autoclaving. IBA was also found to be more stable than IAA in liquid Murashige and Skoog medium (MS) under growth chamber conditions. The stabilities of IBA and IAA were similar in agar-solidified MS. Light provided by cool-white fluorescent bulbs promoted degradation of IAA and IBA in both liquid and agar media. Activated charcoal in concentrations as high as 5% was found to adsorb more than 97% of IAA and IBA in liquid MS. These results have important implications …
