Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

Parameterization Of Food Wastes To Develop An Automatic Recycling System For Livestock And Poultry Feed, Ali Roshanianfard, Samira Nematzadeh, Tarahom Mesri-Gundoshmian

Food wastes are known as one of the big concerns in urban management because of grain consumption gain, environmental pollution, and traditional waste management methods. The reuse of restaurant waste can reduce the cost of producing animal food production. This study attempts to find related parameters to use in the development of an automatic recycling machine and also a suitable method for food waste management (wastes of restaurants in universities and other academic environments) to use in various animal diets. Determination of various parameters including the percentage of dry matter (using a dryer), protein (using Kjeldahl test), fat (using Soxhlet …

To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand

Electronic Theses and Dissertations

Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change …

Species labeling was examined by comparing the species identified with DNA barcoding to the acceptable market names provided in the FDA Seafood …

Fecal Findings: Investigating Eastern Massasauga Rattlesnake Diet Using Dna Metabarcoding, Alyssa Swinehart

Masters Theses

Characterizing the diet of imperiled species using minimally invasive methods is crucial to understanding their conservation requirements. DNA metabarcoding methods have been used to characterize the diet primarily in mammalian systems, while reptiles are heavily underrepresented in this literature. Here, we apply a DNA metabarcoding approach to study the diet of the eastern massasauga rattlesnake (Sistrurus catenatus); a Federally Threatened snake found throughout the Great Lakes Region. Eighty-three fecal samples collected across 10 different massasauga populations located in Michigan were sequenced. We use universal metazoan primers and develop a host-specific oligonucleotide blocker to uncover the full potential diet …

Vera-Berrios, Olaya Alvarez, Raphaëlle Bazire, Pablo Rodríguez Del Río, Marta Vazquez-Ortiz, Joseph L. Baumert, Ronald Van Ree, Clare E.N. Mills, Montserrat Fernandez-Rivas, Jonathan O.B. Hourihane

Department of Food Science and Technology: Faculty Publications

Background: There is increasing interest in the use of eliciting doses (EDs) to inform allergen risk management. The ED can be estimated from the distribution of threshold doses for allergic subjects undergoing food challenges within a specified population. Estimated ED₀₅ values for cow's milk (the dose expected to cause objective allergic symptoms in 5% of the milk-allergic population) range from 0.5 mg to 13.9 mg cow's milk protein. We undertook a single-dose challenge study to validate a predicted ED₀₅ for cow's milk of 0.5 mg protein.

Methods: Participants were recruited from 4 clinical centres. Predetermined criteria were used …

Milk Phospholipids Extraction Using Switchable Solvents, Kaavya Rathnakumar

Electronic Theses and Dissertations

Phospholipids (PLs) found in milk are of great interest due to their health and nutritional benefits associated with their consumption. By-products generated during the manufacture of dairy products represent a source of PLs with potential for value-added opportunities. Currently, the extraction of PLs from by-products results in overall lowefficiencies, and it involves subsequent solvent separation and lipid recovery. This dissertation studied the extraction of milk PLs from by-product streams with a tertiary anime (N, N-dimethyl cyclohexylamine, CyNMe2) as a switchable hydrophilicity solvent. This type of solvents can be reversibly switched between a hydrophobic and hydrophilic form in the presence or …

Arabinoxylan Structural Profiling Of Cool-Season Pasture Grasses Via High-Performance Anion-Exchange Chromatography With Pulsed Amperometric Detection (Hpaec-Pad) Analysis Of Endoxylanase Digests, Glenna Erin Joyce

Theses and Dissertations--Animal and Food Sciences

Arabinoxylan (AX) is a major structural polysaccharide found in the cell walls of monocots such as cereal grains and pasture grasses. The variety of AX structural components and substitution patterns contribute to AX structural diversity between different monocot species as well as plant tissues.

The rumen is the first digestion site of masticated food material in cattle and provides 70% of energy to host through fermentation of forage. There are many species of pasture grasses that act as a forage source. Differences in AX structure found in these pasture grasses may impact rumen microbial fermentation. Understanding the AX structure of …
