  • The Seaweed Flora of a Young Semi-Enclosed Sea: the Baltic
    HELGOL.~NDER MEERESUNTERSUCHUNGEN Helgol&nder Meeresunters. 42, 243-250 (1988) The seaweed flora of a young semi-enclosed sea: The Baltic. Salinity as a possible agent of flora divergence* G. Russell Department of Botany, The University/Liverpool L69 3BX, England ABSTRACT: The salinity tolerances of Baltic and Atlantic populations of Fucus vesiculosus and Chorda filum have been measured using net photosynthesis as an index of tissue damage. Atlantic Fucus proved to have a broader salinity tolerance than Atlantic Chorda, a result which is consistent with others published on the tolerances of intertidal and sublittoral marine species. The optimum salinity for all Atlantic plants was 11 or 34%0, but that of all Baltic plants was 6%o. Baltic Fucus and Chorda were different in breadth of tolerance, in spite of the fact that they inhabit the same sublittoral habitat. This difference is interpreted in relation to their respective life-forms, Fucus being perennial and Chorda annual. Fucus is therefore present as a macrothallus at all times of year, including the critical low-salinity period of the spring ice-melt. Chorda evades damage by existing as a resistent microthallus at this time. It is concluded that the distinctive character of Baltic marine algae deserves nomenclatural recognition at some level below that of the species. The rank of subspecies would appear the most appropriate of those hsted in the Code, but none of those available is able adequately to express the patterns of variation now being reported. INTRODUCTION The Baltic Sea, like the Mediterranean, has a very narrow exit to the Atlantic Ocean, and the fact that the flow of its seawater is almost always in an outward direction, serves only to increase its isolation.

  • Medicinal Values of Seaweeds
    Medicinal Values of Seaweeds Authors Abdul Kader Mohiuddin Assistant Professor, Department of Pharmacy, World University, Dhanmondi, Dhaka, Bangladesh Publication Month and Year: November 2019 Pages: 69 E-BOOK ISBN: 978-81-943354-3-6 Academic Publications C-11, 169, Sector-3, Rohini, Delhi Website: www.publishbookonline.com Email: [email protected] Phone: +91-9999744933 Page | 1 Page | 2 Medicinal Values of Seaweeds Abstract The global economic effect of the five driving chronic diseases- malignancy, diabetes, psychological instability, CVD, and respiratory disease- could reach $47 trillion throughout the following 20 years, as indicated by an examination by the World Economic Forum (WEF). As per the WHO, 80% of the total people principally those of developing countries depend on plant- inferred medicines for social insurance. The indicated efficacies of seaweed inferred phytochemicals are demonstrating incredible potential in obesity, T2DM, metabolic syndrome, CVD, IBD, sexual dysfunction and a few cancers. Hence, WHO, UN-FAO, UNICEF and governments have indicated a developing enthusiasm for these offbeat nourishments with wellbeing advancing impacts. Edible marine macro-algae (seaweed) are of intrigue in view of their incentive in nutrition and medicine. Seaweeds contain a few bioactive substances like polysaccharides, proteins, lipids, polyphenols, and pigments, all of which may have useful wellbeing properties. People devour seaweed as nourishment in different structures: crude as salad and vegetable, pickle with sauce or with vinegar, relish or improved jams and furthermore cooked for vegetable soup. By cultivating seaweed, coastal people are getting an alternative livelihood just as propelling their lives. In 2005, world seaweed generation totaled 14.7 million tons which has dramatically increased (30.4 million tons) in 2015.

Two fractions were obtained by liquid/liquid purification from a crude hydroethanolic extract: (i) an ethyl acetate fraction and (ii) an aqueous fraction. Total phenolic contents and antioxidant activities of extract and both fractions were assessed by in vitro tests (Folin–Ciocalteu test, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, reducing power assay, superoxide anion scavenging assay, and β-carotene–linoleic acid system).

To the best of my knowledge and belief, this thesis contains no material previously published or written by another person, except where due acknowledgement is made in the text. Joseph Peter Valentine Statement of Authority of Access This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968. Joseph Peter Valentine DI Acknowledgements To begin I would like to thank my supervisor, Craig Johnson for his encouragement and support over the duration of the project. Your efforts to secure funds made this work possible and for that I am very grateful. Your help and advice on experimental design and analysis was also appreciated, as was your understanding during some challenging times. An intensive diving project such as this one cannot be completed successfully (and safely) without a reliable diving buddy. This work could not have been conducted without the help of my fellow PhD student and friend Hugh Pederson. Hugh's assistance and advice above and below the water, particularly on all things mechanical was invaluable. I also appreciate Hugh's understanding in accommodating field schedules to meet the needs of both of our projects. It was not all hard work though- a tough day of Undaria surveying around Maria Island was often rounded out by fine cuisine, with 'Peanut butter chicken' a favourite.

  • Biologically Active Compounds in Seaweed Extracts Useful in Animal Diet
    20 The Open Conference Proceedings Journal, 2012, 3, (Suppl 1-M4) 20-28 Open Access Biologically Active Compounds in Seaweed Extracts - the Prospects for the Application Katarzyna Chojnacka*, Agnieszka Saeid, Zuzanna Witkowska and Łukasz Tuhy Institute of Inorganic Technology and Mineral Fertilizers, Wroclaw University of Technology ul. Smoluchowskiego 25, 50-372 Wroclaw, Poland Abstract: The paper covers the latest developments in research on the utilitarian properties of algal extracts. Their appli- cation as the components of pharmaceuticals, feeds for animals and fertilizers was discussed. The classes of various bio- logically active compounds were characterized in terms of their role and the mechanism of action in an organism of hu- man, animal and plant. Recently, many papers have been published which discuss the methods of manufacture and the composition of algal ex- tracts. The general conclusion is that the composition of extracts strongly depends on the raw material (geographical loca- tion of harvested algae and algal species) as well as on the extraction method. The biologically active compounds which are transferred from the biomass of algae to the liquid phase include polysaccharides, proteins, polyunsaturated fatty ac- ids, pigments, polyphenols, minerals, plant growth hormones and other. They have well documented beneficial effect on humans, animals and plants, mainly by protection of an organism from biotic and abiotic stress (antibacterial activity, scavenging of free radicals, host defense activity etc.) and can be valuable components of pharmaceuticals, feed additives and fertilizers. Keywords: Algal extracts, feed additives, fertilizers, pharmaceuticals, biologically active compounds. 1. INTRODUCTION was paid to biologically active compounds, useful as the components of pharmaceuticals, feeds and fertilizers.

This area is home to approximately 200 different species of macroalgae, representing the three major phyla of the green algae (Chlorophyta), brown algae (Ochrophyta) and the red algae (Rhodophyta), respectively. Over almost 50 years, the species of macroalgae associated and occurring within this area have resulted in the identification of a number of different types of secondary metabolites including terpenoids, sterols/steroids, phenolic acids, phenols, lipids/polyenes, pheromones, xanthophylls and phloroglucinols. Many of these compounds have subsequently displayed a variety of bioactivities. A systematic description of the compound classes and their associated bioactivities from marine macroalgae found within this region is presented. Keywords: marine macroalgae; bioactivity; secondary metabolites 1.
