Valorisation of natural extracts from marine source focused on marine by-products: A review

Food Research International, 2010

The wide chemical and biological diversity observed in the marine environment makes the ocean an extraordinary source of high added value compounds (HAVC) which can be employed in many applications. Minerals, lipids, amino acids, polysaccharides and proteins from marine sources have unique features and, surprisingly, their highest concentration is often found in parts of marine organisms that are commonly discarded. Fish heads, viscera, skin, tails, offal and blood, as well as seafood shells possess several HAVC suitable for human health applications, yet most end up as residues throughout the raw material processing. This review updates information on this issue and conveys critical analysis of the chief methodologies to carry out extraction, purification and eventual transformation, with a focus on their actual and potential applications.

Mining marine shellfish wastes for bioactive molecules: Chitin and chitosan – Part B: Applications

Biotechnology Journal, 2008

Due to their unique chemical characteristics (including biodegradability to non-toxic products, physiological inertness and hydrophilicity), chitin, chitosan and their derivatives may be expansively utilized in the biotechnological, agricultural, food protection and nutraceutical, medicinal and pharmacological fields and in the areas of bioremediation and gene therapy. Biological actions associated with chitin and shell waste by-products include among others antibacterial, angiotensin-1-converting enzyme-inhibitory and immunomodulatory activities, while the chitinolytic microbes and enzymes associated with chitinolysis also play a role in the de novo generation of further bioactivites. In Part B of this review we relate in more detail some of the bioactivities and applications of chitin and shell waste by-products.

Exploring the Potential Bioactive Properties of Marine Natural Products

Background: The marine world is highly diversified and is of great importance for its sustainable utilization as resources for human life. Although marine resource economy has its own share in the international market, there is only a handful of research occurring, the probability of not being completely explored. It has now become virtually possible to characterize the metabolites by bioanalytical techniques and molecular biology methodology. The marine biomes harbour largely diatoms, bacteria, fungi, actinomycetes, and cyanobacteria that are harnessed for their rich structurally diverse secondary metabolites. Recently, sponges and algae have gained commercial importance. Focuses are now shifting towards ascomycota, actinobacteria, cyanobacteria and other classes due to the advanced technology in extraction of the active components from these phyla and deeper exploration of the oceans. Method: A vast report on marine natural products have been regularly updated and published which clearly indicates the immense research undertaken in ocean flora and fauna. Herein we focus on providing information on the potential uses of marine natural products as bioactive agents in the last five years. The data were collected from research and review articles from peer-reviewed journals. Results: A total of 128 articles are citied in the present review covering broad spectrum of marine organism and their importance in the field of medical biology. Information on source organisms, collection sites, was assembled and a total of 120 biologically important compounds are described here. Conclusion: The present study provides information to bioprospecting efforts in the field of marine science. Herein, I have emphasized diverse biological activities isolated from marine microbes to invertebrate against many pathogenic microorganisms and cancer, thus making marine-derived natural products valuable commodities. Future prospects for the discovery of new marine products and process development could add to the economic importance.

Bioactive Compounds of Nutraceutical Value from Fishery and Aquaculture Discards

Foods

Seafood by-products, produced by a range of different organisms, such as fishes, shellfishes, squids, and bivalves, are usually discarded as wastes, despite their possible use for innovative formulations of functional foods. Considering that “wastes” of industrial processing represent up to 75% of the whole organisms, the loss of profit may be coupled with the loss of ecological sustainability, due to the scarce recycling of natural resources. Fish head, viscera, skin, bones, scales, as well as exoskeletons, pens, ink, and clam shells can be considered as useful wastes, in various weight percentages, according to the considered species and taxa. Besides several protein sources, still underexploited, the most interesting applications of fisheries and aquaculture by-products are foreseen in the biotechnological field. In fact, by-products obtained from marine sources may supply bioactive molecules, such as collagen, peptides, polyunsaturated fatty acids, antioxidant compounds, and chi...

Mining marine shellfish wastes for bioactive molecules: Chitin and chitosan ndash; Part A: extraction methods

Biotechnology Journal, 2008

Legal restrictions, high costs and environmental problems regarding the disposal of marine processing wastes have led to amplified interest in biotechnology research concerning the identification and extraction of additional high grade, low-volume by-products produced from shellfish waste treatments. Shellfish waste consisting of crustacean exoskeletons is currently the main source of biomass for chitin production. Chitin is a polysaccharide composed of N-acetyl-D-glucosamine units and the multidimensional utilization of chitin derivatives including chitosan, a deacetylated derivative of chitin, is due to a number of characteristics including: their polyelectrolyte and cationic nature, the presence of reactive groups, high adsorption capacities, bacteriostatic and fungistatic influences, making them very versatile biomolecules. Part A of this review aims to consolidate useful information concerning the methods used to extract and characterize chitin, chitosan and glucosamine obtained through industrial, microbial and enzymatic hydrolysis of shellfish waste.
