Marine organisms are constituted by materials with a vast range of properties and characteristics that may justify their potential application within the biomedical field. Moreover, assuring the sustainable exploitation of natural marine resources, the valorisation of residues from marine origin, like those obtained from food processing, constitutes a highly interesting platform for development of novel biomaterials, with both economic and environmental benefits. In this perspective, an increasing number of different types of compounds are being isolated from aquatic organisms and transformed into profitable products for health applications, including controlled drug delivery and tissue engineering devices. This report reviews the work that is being developed on the isolation and characterisation of some polysaccharides, proteins, glycosaminoglycans and ceramics from marine raw materials. Emphasis is given to agar, alginates, carrageenans, chitin and chitosan, among other polysaccharides, collagen, glycosaminoglycans such as chondroitin sulphate, heparin and hyaluronic acid, calcium phosphorous compounds and biosilica. Finally, this report ends by reviewing the application of the previously mentioned materials on specific biomedical applications, in particular their participation on the development of controlled drug delivery systems and tissue engineering scaffolds.

Future studies may address the effect of prolonged exposure to healthy eating cartoons. Cartoons can be used to promote healthy food choices and can be a part of health promotion campaigns.

BACKGROUND Corbicula fluminea is an invasive freshwater clam with strong environmental and economic impact. Management of this pest should include its application, thus biofiltration by C. fluminea was successfully tested for the treatment of winery wastewater. Fenton's process was used in order to reduce the initial effluent toxicity. RESULTS Clam mortality was observed to significantly decrease when exposed to Fenton‐treated samples compared with untreated wastewater. Although COD depletion by oxidation was strongly affected by the reactant concentration applied, the toxicity of the output effluent did not change markedly even when higher iron and hydrogen peroxide loads were used. Biofiltration led to COD abatements near 100% both when applied to raw and Fenton‐treated effluents. However, for the raw effluent significant COD removal occurred only after an initial period where the organic load remained unchanged. CONCLUSION It seems advisable to integrate biofiltration with Fenton's peroxidation as a pre‐treatment. The results discussed here support the integration of C. fluminea in wastewater treatment as a potential contribution to pest management. © 2017 Society of Chemical Industry
