PHOTOADAPTIVE RESPONSES IN THE TROPICAL BROWN SEAWEED, LOBOPHORA VARIEGATA (LAMOUR) WOMERS
… relationships of the tropical brown seaweed, Lobophora variegata. Pigment analyses were performed on samples collected from a series of depths between 9 and 49m. Chlorophyll a, chlorophyll c, and fucoxanthin were constant on a thallus weight basis, but showed small decreases …

Development and Characterization of sustainable Materials from invasive brown Seaweed Ruguopteryx okamurae
… investigates the valorization of the invasive brown seaweed Rugulopteryx okamurae as a raw material for bioplastic production and sustainable composites. As an invasive species in the Mediterranean Sea, Rugulopteryx okamurae poses a significant threat to biodiversity. Its proliferation disrupts …

The potential applications of brown seaweed as an alternative feed for ruminant livestock
… feasibility and potential benefits of feeding brown seaweed to ruminant livestock. The primary objectives of this research were to: identify gaps in current knowledge on the potential use of brown seaweed as a feed source for ruminant livestock; to establish a baseline knowledge of the …

Investigating factors affecting the anaerobic digestion of seaweed: modelling and experimental approaches
… fertiliser and land for their cultivation. Seaweeds are of particular interest as they are characterised by high biomass yields and interesting conversion rates. In temperate seas, brown seaweed species generally dominate the flora and their relative abundance on the sublittoral zone of the …

Assessment of a marine polysaccharide for use as excipient in pharmaceutical hot-melt extrusion
… Keltone, a marine polysaccharide derived from brown seaweed, as a polymeric excipient for pharmaceutical HME is explored. Keltone is insoluble in acidic pH and soluble in basic pH, therefore making it suitable for intestinal drug release. The processability of Keltone by extrusion using water …

Perspectives on third generation gaseous biofuel
… for a tubular photo-bioreactor. Macro-algae (seaweed) can also be produced by sequestering nitrogen from waste streams that are released by fish farms. A production of 168Mt of seaweed integrated with 13Mt of farmed salmon is required if 1.25 % of energy in transport is to be provided by …

The Bioactivity and Natural Products of Scottish Seaweeds
Seaweed has traditionally been used in Scotland and other countries both as food and for medicinal purposes, which has led to seaweed being investigated for their natural product content. Despite over 30 years of research, the majority of species found in Scotland have yet to have their chemistry …

Natural biosorbents for the removal of metals from aqueous solutions
… characteristics to perform as biosorbents. Brown seaweed (Fucus vesiculosus), Douglas fir wood bark (Pseudolsuga menziesii), peat and carapace from the edible crab (Cancer pagurus) were assessed for Cu(II) removal as a function of time and concentration. Mechanically and commercially milled …

Arsenic in the Pak Pa-Nang River Basin, Thailand
… and real samples, mussel, cockle, green seaweed, brown seaweed and sediment collected from the Tamar Estuary, UK. Fish samples from the Pak Pa-Nang Estuary showed a range for total arsenic concentration, up to 17 µg gˉ¹ dry mass. The highest total arsenic found in plant samples was 189 µg …

Biomarkers (lipids, fatty acids and stable isotopes) to examine diet of the sea urchin Evechinus chloroticus.
… Gulf revealed a digestive pathway from the brown seaweed, especially E. radiata, to gut contents, gut and gonads, confirming the storage role for nutrients played by gonads in sea urchins. Biosynthesis and selective retention of essential fatty acids seen in the gonads confirm their dual …

Alginate and laminarin degrading enzymes from Vibrio splendidus and Vibrio breoganii
… 13B01, and V. breoganii 1C10 metabolize brown seaweeds. Brown seaweeds have many advantages over terrestrial feedstocks, including fast growth and non-recalcitrant carbon feedstocks, so brown seaweeds are an attractive target for industrial fermentation. Alginate and laminarin are two …
