Broth: Enhancing Market Opportunities And Improving Sustainability Of Maine Farmed Seaweed, Zachary M. Bonelli Aug 2018

Broth: Enhancing Market Opportunities And Improving Sustainability Of Maine Farmed Seaweed, Zachary M. Bonelli

Electronic Theses and Dissertations

Seaweed is becoming popular across the world as consumers learn about the variety of seaweed-based products and their health benefits. Sugar kelp is one of Maine’s seaweed varieties that is locally grown each year. Sugar kelp and similar species contain many useful nutrients including iodine, calcium, magnesium, iron, and vitamins A, B, C, and E. Even though the health benefits of seaweed have been proven, locally-sourced seaweed has not yet become any more popular in Maine. Part one of this study identified suitable processing steps for a sugar kelp-based broth. Part two assessed how consumers’ demographics and food neophobia, as …


Propagation Of The Native North American Shrub Lonicera Villosa And Trait Comparisons With Nonnative Congeneric Taxa, Darren J. Hayes Aug 2018

Propagation Of The Native North American Shrub Lonicera Villosa And Trait Comparisons With Nonnative Congeneric Taxa, Darren J. Hayes

Electronic Theses and Dissertations

The honeysuckles, or Lonicera, represent a circumboreally-distributed genus in the Caprifoliaceae family. A diverse assortment of vines, lianas, and shrubs comprise the genus, and honeysuckles have long been a staple of the horticultural industry, prized for their robustness as much as their sweet-scented flowers and colorful fruits. However, many cultivated honeysuckles of Eurasian origin have proven invasive outside of their native range, displacing native species and reducing overall diversity and ecosystem health. Planting of Eurasian Lonicera taxa is now often discouraged or banned throughout much of North America. Conversely, native North American Lonicera species are often sparsely distributed and …


Estimating Ecosystem Services From Harvested And Unharvested Ascophyllum Nodosum On The Maine Coast, Ashley E. Sarra May 2018

Estimating Ecosystem Services From Harvested And Unharvested Ascophyllum Nodosum On The Maine Coast, Ashley E. Sarra

Honors College

Ascophyllum nodosum, better known as rockweed, is a commercially important, harvested intertidal brown alga species common in coastal Maine. Rockweed sea vegetable harvesting is a lucrative wild harvest fishery, that has also proved to be socially contentious and whose future management is uncertain. A. nodosum is an intertidal macroalgal species that may also be impacted by sea level rise. Through a combination of biomass estimation, newspaper analysis, and interview data collection, this project seeks to (a) develop a typology of ecological services of A. nodosum in harvested and unharvested areas in the state of Maine; and (b) assess the …


Red Abalone Hemocyanin As An Alternative Hapten-Carrier For Vaccine Production, Isaiah N. Mansour May 2018

Red Abalone Hemocyanin As An Alternative Hapten-Carrier For Vaccine Production, Isaiah N. Mansour

Honors College

Vaccines protect millions of human lives per year from otherwise fatal illnesses. Vaccination promotes immunity by simulating infection with a non-pathogenic representative of the disease, an antigen, to prepare and train an immune response. Vaccine-safe antigens are often too small to elicit an immune response. These non-immunogenic molecules are referred to as haptens and are introduced to the immune system by hapten-carriers, large immune-stimulating proteins. Keyhole Limpet Hemocyanin (KLH), a respiratory protein of the giant keyhole limpet (Megathura crenulata), is the industry standard hapten-carrier. KLH is a potent yet safe immune-stimulant relied upon in research, available human medications, and emerging …
