Methods for Ethanol Production from the Enzymatic Hydrolysis and Fermentation of Sugar Beet Pulp
(North Dakota State University, 2010)Sugar beet pulp (SBP), the residue remaining after sucrose extraction, is currently sold as an animal feed. Humans cannot digest the cellulose in the pulp unlike ruminant animals. The pulp is primarily comprised of ... -
Rapid Evaluation of Canola Lines for Cold Soak Filterability in Biodiesel
(North Dakota State University, 2010)Worldwide concerns about fossil fuel depletion and energy security have recently triggered a research interest in biodiesel, which is renewable, biodegradable, and has several other advantages as an alternative to petro ... -
Reference Evapotranspiration and Actual Evapotranspiration Measurements in Southeastern North Dakota
(North Dakota State University, 2011)Subsurface drainage (SSD) has been used to remove excess water from fields in the United States upper Midwest for more than a century, but only since the last decade in the Red River Basin of the North in North Dakota (ND). ... -
Application of SWAT for Impact Analysis of Subsurface Drainage on Streamflows in a Snow Dominated Watershed
(North Dakota State University, 2011)The wet weather pattern since the early 1990's has created two problems for the people living in the Red River Valley (RRV): (1) wet field conditions for farmers and (2) more frequent major spring floods in the Red River ... -
Evaluating Standard Wet Chemistry Techniques and NIR Spectroscopic Models for Determining Composition and Potential Ethanol Yields of Multi-Species Herbaceous Bioenergy Crops
(North Dakota State University, 2011)Herbaceous perennials represent a considerable portion of potential biomass feedstocks available for the growing bioenergy industry. Their chemical composition and biomass yields, which are important in determining ethanol ... -
Anaerobic Co-digestion of Dairy Manure with Canola Meal
(North Dakota State University, 2011)There has been an increase of confined animal feeding operations (CAFOs) generating large amounts of manure. When this manure is not handled properly, it generates greenhouse gases (GHGs), odors and water pollution. ... -
Combined Effect of Densification and Pretreatment on Cellulosic Ethanol Production
(North Dakota State University, 2012)Biomass densification enhances material stability, improves flowability, and decreases both handling and transportation costs. The effect of densification, before or after pretreatment, was tested to determine the effect ... -
Evaluation of Storage Techniques to Preserve Fermentable Sugars from Sugar Beets for Ethanol Production
(North Dakota State University, 2012)New sugar beet varieties may qualify as an advanced biofuel feedstock in the U.S., but new alternatives to conventional pile storage are necessary to preserve fermentable sugars and allow yearlong beet ethanol production. ... -
Vegetative Filter Strip: A Best Management Practice (Bmp) for Feedlot Runoff Pollution Control in North Dakota
(North Dakota State University, 2013)Runoff from animal feeding operations is a major source of water pollution. Vegetative filter strips (VFS) are effective ways to reduce nonpoint source pollution. In this study, vegetative filter strips with different ... -
Non-Destructive Analysis of Single Plant Canola (Brassica Napus) Seed Using Near Infrared Spectroscopy
(North Dakota State University, 2013)Near Infrared Spectroscopy (NIRS) is widely used for quantitative analysis of oilseeds in a non-destructive manner. Canola (Brassica napus) is a popular oilseed crop that is used for food and biofuel markets. Due to limited ... -
Remediation of Feedlot Nutrients Runoff by Hydroponic Treatment and Electrolysis Process
(North Dakota State University, 2014)Intensive livestock farming in feedlot producing large amounts of manure and wastewater. Hydroponic and electrolysis treatments were studied for the remediation of nutrients from feedlot runoff. Water hyacinth, water ... -
Efficacy and Recovery of Cellulases Immobilized on Polymer Brushes Grafted on Silica Nanoparticles
(North Dakota State University, 2014)Cellulosic biofuels can be more economical if cellulases are recovered and reused. Cellulase and β-glucosidase were immobilized on poly(acrylic acid) brush particles. Impact of brush enzyme density on efficacy and recovery ... -
Technical and Economic Assessments of Storage Techniques for Long-term Retention of Industrial-beet Sugar for Non-food Industrial Fermentations
(North Dakota State University, 2015)Industrial beets may compete against corn grain as an important source of sugars for non-food industrial fermentations. However, dependable and energy-efficient systems for beet sugar storage and processing are necessary ... -
Pilot Scale Production, Characterization, and Optimization of Epoxidized Vegetable Oil-Based Resin
(North Dakota State University, 2015)Novel epoxidized sucrose soyate (ESS) resins perform much better than other vegetable oil-based resins; thus, they are of current interest for commercial scale production and for a wide range of applications in coatings ... -
Bioavailability and Biodegradability of Dissolved Organic Nitrogen Originated From Municipal and Animal Wastewater
(North Dakota State University, 2015)Due to the increased concern on dissolved organic nitrogen (DON) in surface waters, it is necessary to understand the biodegradability and bioavailability of DON in point and non-point sources. In this study, algae and ... -
Evaluation of Different Techniques to Control Hydrogen Sulfide and Greenhouse Gases from Animal Production Systems
(North Dakota State University, 2015)The livestock manure management sector is one of the prime sources for the emission of greenhouse gases (GHGs) and other pollutant gases such as ammonia (NH3) and hydrogen sulfide (H2S), which may affect the human health, ... -
Effects of Calcium Based Surface Amendments on Hydraulic Conductivity and Selected Physical Properties of Subsurface Drained Sodic Soils
(North Dakota State University, 2016)Managing excess soil water in agricultural fields in the Northern Great Plains through subsurface drainage increases the risk of sodification in high-risk soils. Leaching sodic soils with low electrical conductivity (EC) ... -
