“…Characteristic pyrolysis products of fucoidan, mannitol, laminarin, and alginic acid were identified in all five seaweed species, but amounts varied among species. Further, there were differences in fatty acid profiles (Shekhar et al 2012). Similar variations in compositional analysis were observed with four commercial formulations and two acidic extracts of A. nodusum (Shekhar et al 2012).…”

“…Extracts are active as biostimulants at low concentrations (diluted at 1:1,000 or more), suggesting that the effects observed are likely distinct from those associated with a direct nutritional function van Staden 1993, Khan et al 2009). Seaweed extracts are a complex mixture of components that may vary according to the seaweed source, the season of collection, and the extraction process used (Khan et al 2009;Rioux et al 2009;Sharma et al 2012;Shekhar et al 2012). They contain a wide range of organic and mineral components including unique and complex polysaccharides not present in terrestrial plants such as laminarin, fucoidan and alginates, and plant hormones (Sivasankari et al 2006;Rioux et al 2007;Khan et al 2009).…”

Recently (Sharma et al 2012) and (Shekhar et al 2012) reported on the compositional analysis of five brown seaweed species from Northern Ireland. Carbon, nitrogen, lipid, and ash contents varied significantly among species with time of collection and type of extraction, and ranged between 25 and 39 %, 1 and 3 %, 1 and 4 %, and 18 and 48 %, respectively.…”

Background Plant biostimulants are diverse substances and microorganisms used to enhance plant growth. The global market for biostimulants is projected to increase 12 % per year and reach over $2,200 million by 2018. Despite the growing use of biostimulants in agriculture, many in the scientific community consider biostimulants to be lacking peer-reviewed scientific evaluation. Scope This article describes the emerging definitions of biostimulants and reviews the literature on five categories of biostimulants: i. microbial inoculants, ii. humic acids, iii. fulvic acids, iv. protein hydrolysates and amino acids, and v. seaweed extracts.Conclusions The large number of publications cited for each category of biostimulants demonstrates that there is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species. The cited literature also reveals some commonalities in plant responses to different biostimulants, such as increased root growth, enhanced nutrient uptake, and stress tolerance.

Golden Tides: Problem or Golden Opportunity? The Valorisation of Sargassum from Beach Inundations

Abstract:In recent years there have been massive inundations of pelagic Sargassum, known as golden tides, on the beaches of the Caribbean, Gulf of Mexico, and West Africa, causing considerable damage to the local economy and environment. Commercial exploration of this biomass for food, fuel, and pharmaceutical products could fund clean-up and offset the economic impact of these golden tides. This paper reviews the potential uses and obstacles for exploitation of pelagic Sargassum. Although Sargassum has considerable potential as a source of biochemicals, feed, food, fertiliser, and fuel, variable and undefined composition together with the possible presence of marine pollutants may make golden tides unsuitable for food, nutraceuticals, and pharmaceuticals and limit their use in feed and fertilisers. Discontinuous and unreliable supply of Sargassum also presents considerable challenges. Low-cost methods of preservation such as solar drying and ensiling may address the problem of discontinuity. The use of processes that can handle a variety of biological and waste feedstocks in addition to Sargassum is a solution to unreliable supply, and anaerobic digestion for the production of biogas is one such process. More research is needed to characterise golden tides and identify and develop commercial products and processes.
