The influence of hydrodynamics on the growth, erosion and biomechanical properties of Laminaria digitata
… offshore sediments. Macroalgae such as the kelp Laminaria digitata are found in temperate waters growing in the low intertidal region along energetic coastlines exposed to a range of hydrodynamic environments. The influence of water motion on fundamental processes such as growth, erosion and the …

An investigation of the prebiotic potential and gut health benefits of Irish seaweeds
… similarly processed extracts from the seaweed Laminaria digitata were prepared to study the effect of depolymerisation with hydrogen peroxide on prebiotic potential. Depolymerisation significantly increased propionate production and reduced butyrate production. Modulation of polysaccharide …

Perspectives on third generation gaseous biofuel
… in coastal digesters. Brown seaweed such as Laminaria digitata was subjected to a two-stage fermentation process that involved hydrolysis followed by methanation. It was found that two stage fermentation of L. digitata can be implemented if shorter retention times and higher organic loading …

Molecular biology approach to anaerobic digestion of marine biomass: Anaerobic digestion from marine materials. What makes a methanogen happy?
… and process functions. Selected seaweeds (Laminaria digitata, Saccharina lattissima and Fucus serratus) found commonly on the west coast of Scotland were subjected to 50-day anaerobic batch digestion using different inoculum sources. A number of molecular techniques including, denaturing …

ECOLOGY OF ROCKY SUBTIDAL COMMUNITIES: THE ROLE OF MODIOLUS MODIOLUS (L) AND THE INFLUENCE OF DISTURBANCE, COMPETITION, AND MUTUALISM
… not at shallow depths (4-8 m) dominated by kelp (Laminaria digitata, Laminaria saccharina). Experiments indicated that chronic storm-generated disturbance caused massive dislodgement of mussels competitively overgrown by kelp, and could account for the scarcity of Modiolus at shallow depths. The …

Biomethane production from macroalgae
… technologies to enhance potential gas yields. Laminaria digitata and Ascophyllum nodosum were tested for seasonal variation. From the characterization and batch digestion of L. digitata, August was found to be the optimal month for harvest due to high organic matter content, low level of ash …

Immunostimulatory effects of different aspects of aquaculture on the host response in the edible sea urchin, paracentrotus lividus
… which led to Chapter 3. In this chapter, both Laminaria digitata and Mytilus edulis were shown to influence measured immune parameters of differential cell counts, nitric oxide production, and lysozyme activity. Therefore, trials commencing after Trial 5 in Chapter 4, were modified to include …

The potential applications of brown seaweed as an alternative feed for ruminant livestock
… (L.) Le Jolis, Fucusvesiculosus Linnaeus, Laminaria digitata (Hudson)J.V. Lamouroux and Saccharina latissimi (L.) C.E. Lane, C. Mayes,Druehl & G.W. Saunders) were chosen based on their availability in NorthernAtlantic regions. The chemical composition and in vitro drymatter digestibility of …

Bioethanol Production from Macroalgae
… kelp species chosen as biomass candidates were Laminaria digitata, Laminaria hyperborea, Saccharina latissima and Alaria esculenta due to their abundance in Scottish waters and their identified potential for mariculturing.<br/>These kelp species were chemically characterised to identify seasonal …

International biogas applications
… and methane co-production using macro-algae (Laminaria digitata) and micro-algae (Arthrospira platensis) was tested in laboratory trials. The hydraulic retention time (HRT) of the H2 reactor was set at 4 days. The highest hydrogen yield was obtained at an OLR of 6 kgVS/m3 /d. In the …

Investigating factors affecting the anaerobic digestion of seaweed: modelling and experimental approaches
… the anaerobic co-digestion of brown seaweed (<i>Laminaria digitata</i>) and vegetable residues was also investigated. Experimental results were successfully modelled using an extensively modified version of the ADM1, which introduces an uncompetitive function to the rate of acetate uptake in …
