Bioactivity and Applications of Sulphated Polysaccharides from Marine Microalgae

Tuesday, March 15, 2016 9:38:40 AM East Boothbay, Maine

Bioactivity and Applications of Sulphated Polysaccharides from Marine Microalgae

Maria Filomena de Jesus RaposoRui Manuel Santos Costa de Morais and Alcina Maria Miranda Bernardo de Morais 

Mar. Drugs 201311, 233-252; doi:10.3390/md11010233

The authors review current research on the biological activities and applications of polysaccharides, active biocompounds synthesized by marine microalgae.  While marine polysaccharides (such as fucoidan, carrageenan, alginate, and agar) have long been known for their texture-improving properties in food and cosmetics, recent research describes their potential for other biological applications and health benefits ranging from nutraceuticals, to therapeutic agents, to cosmetics and other areas such as lubricants.

The authors go on to specify strains of marine microalgae and the type of polysaccharides they produce.  According to the authors there are extensive publications on the applications of microalgal biomass and biocompounds produced by microalgae, including literature on the antiviral activity of the polysaccharides produced by some microalgae, but little has been published in other areas and only dealing with a few marine species. Areas ripe for further investigation using marine microalgae polysaccharides in the following applications include:

  • Antioxidants and Free Radical Scavenging
  • Anti-inflammatory and Immunomodulatory Actvities
  • Inhibition of Tumor Cell Growth
  • Hypolipidaemic and Hypoglycaemic Properties
  • Anticoagulant and Antithrombotic Activity
  • Biolubricant Properties
  • Drag-Reducers

 

 The authors also cite advantages of working with microalgae for investigations into the properties they produce, including:

  • Easy to grow and culture
  • Harvesting does not depend on the weather or season
  • Growth can be easily controlled

 

Should you choose to investigate the many potential new applications of polysaccharides, we invite you to contact the National Center For Marine Algae and Microbiota (NCMA).  We have hundreds of strains of polysaccharide-producing microalgae that are available to the research community.  We also offer counsel on how to grow, culture, and maintain strains to ensure productive research results.  

NCMA maintains a diverse collection of marine microalgae strains to be available to the research and biotech communities to conduct further studies.  We currently maintain around 3,000 strains of which a subset have been shown to produce extracellular polysaccharides, sulfated polysaccharides or their derivatives.

Table 1 below is a modification of information originally presented in the publication.  It shows the group of algae, number of strains available in the NCMA collection and the type of polysaccharide it produces.  We have also included the NCMA Commercialization index, which is an indicator of how easy the strain is to grow.  The NCMA Commercialization Index is based on the 30 years experience of our curators maintaining the collection.

Coccolithophores

Monday, November 30, 2015 3:49:31 PM East Boothbay, Maine

Coccolithophores are often referred to as "canaries in the coal mine."  The results of a recent study published in Science showed that a dramatic increase in coccolithophore population contradicted the hypothesis of scientists. Until this data proved otherwise, scientists thought that coccolithophores would have more difficulties forming their calcite plates in a more acidic ocean.  The results, however, show that coccolithophores are able to use the higher concentration of carbon derived from CO2, combined with warmer temperatures, to increase their growth rate.

New Genus for the Globular Species of the Dinoflagellate Gambierdiscus (Dinophyceae)

Friday, November 13, 2015 3:20:43 PM East Boothbay, Maine

The dinoflagellate genus Gambierdiscus is a toxicologically important genus responsible for ciguatera fish poisoning, the principal cause of non-bacterial illness associated with fish consumption. The genus currently contains species exhibiting either globular or anterior-posteriorly compressed morphologies with marked differences in cell shape and plate arrangement. Fukuyoa, a genus of dinoflagellate that is found in similar habitats as Gambierdiscus, with a vague resemblance to Gambierdiscus, has recently been isolated from a sandy beach in Ubatuba, Brazil. It is a close relative to Gambierdiscus but differs not only in its morphology (plate pattern, shape is more lentil-like therefore just slightly laterally compressed) and DNA sequence (large and small subunit ribosomal DNA sequences), but in its toxicity in that it is not toxic (it was tested according to the procedure described by Xu et al. (Harmful Algae 2014; 34: 56–68). 

The NCMA is contiually adding to the public collection to create the most diverse collection possible by bringing in newly named genera and type strains. We are pleased to have been able to access CCMP3447 Fukuyoa paulensis, thanks to the authors of the paper describing this new species (see below).  It grows well at 24 degrees C in L1-Si medium made using our local seawater.
