By E. Percival and R. McDowellAuthor: E. Husemann. Algal polysaccharides are obtained from algae. Marine algae contain high amount of polysaccharides including mucopolysaccharides, cell wall–structured, and storage polysaccharides. Polysaccharides content in some seaweed species ranges from 4% to 76% of their total dry by: 7.

The nomenclature of red algal galactans used in most of the papers is rather arbitrary. The terms ‘agar’, ‘agarose’ and ‘carrageenan’ are widely used together with names given to polysaccharides before elucidation of their chemical nature, according to their biological source, such as porphyran 5 from algae of the genus Porphyra (Anderson and Rees, ), odonthalan from Cited by: Percival E, McDowel RH () Chemistry and enzymology of marine algal polysaccharides.

Marine seaweeds increasingly grow into extensive algal blooms, which are detrimental to coastal ecosystems, tourism and aquaculture. However, algal biomass is also emerging as a sustainable raw. Marine seaweeds and algae enriched with polysaccharides such as glycosaminoglycans, agar, alginate and chitin/chitosan owing to their diversified significance have received growing attention among researchers.

Currently, marine‐derived biomolecules cater 20% market drug load while other natural products bear 30% share. Microorganisms are able to produce enzymes such as glucosidases, sulfatases, lipases, and proteases, among others, that could be employed in a variety of industrial and environmental applications.

The plant cell wall and polysaccharides synthesized by marine algae. Over the years, brown algae bioactive polysaccharides laminarin, alginate and fucoidan have been isolated and used in functional foods, cosmeceutical and pharmaceutical industries.

The extraction process of these polysaccharides includes several complex and time-consuming steps and the correct adjustment of extraction parameters (e.g., time, temperature, power, pressure, solvent and sample to. Consequently, the main scope of this Special Issue is to provide an overview of the extraction, chemical characterization and biological applications of the most important plant, algal and fungal polysaccharides and derivatives such as oligosaccharides and low molecular weight fractions, and related enzymes.

Polysaccharides form the basis for useful products, like xanthan gum, dextran, welan gum, gellan gum, diutan gum and pullulan. Some of the polysaccharide-derived products have interesting and useful properties and show biological activities, such as immunomodulatory, antibacterial, anti-mutagenic, radioprotective, anti-oxidative, anti-ulcer.

other marine sources. To date, he has authored around research papers, has edited more than 20 books and holds 76 patents. Marine Algae Derived Polysaccharides for Bone. The novel enzymes described here may find value in new bio-based industries and advance our understanding of the mechanisms responsible for recycling of red algal polysaccharides in marine.

However, algal biomass is also emerging as a sustainable raw material for the bioeconomy. The potential exploitation of algae is hindered by our limited knowledge of the microbial pathways-and hence the distinct biochemical functions of the enzymes involved-that convert algal polysaccharides into oligo- and monosaccharides.

Colorimetric Determination of 3,6-Anhydrogalactose and Galactose in Marine Algal Polysaccharides. Prof. Se-Kwon Kim has more than 40 years of experience as a marine biochemist, working in the field of marine bioprocess and biotechnology. He holds a professorship of marine biochemistry at the Pukyong National University, Pusan, South Korea and is the director of the Marine Bioprocess Research Center in Pusan, Korea.

Prof. The emphasis is on marine biomacromolecules namely hyaluronic acid, chitin and chitosan, peptides, collagen, enzymes, polysaccharides from algae, and secondary metabolites like mycosporines. Marine microbes are a rich source of enzymes for the degradation of diverse polysaccharides.

Paraglaciecola hydrolytica S66 T is a marine bacterium capable of hydrolyzing polysaccharides found in the cell wall of red macroalgae. In this study, we applied an approach combining genomic mining with functional analysis to uncover the potential of this bacterium to produce enzymes. The evaluation of some red marine algae as a source of carrageenan and of its κ- and λ-components.

The enzymes have been isolated from various kinds of organisms with different substrate specificities, including algae, marine mollusks, marine and terrestrial bacteria, and some viruses and fungi.

Macroalgae, such as red algae, green algae, and brown algae, as a substantial fraction of marine biomass are the main source for marine carbon cycling. The polysaccharides are the main components of the cell walls of algae, which have been widely applied in the food and medicine industries because of their various physiological activities.

Marine Carbohydrates: Fundamentals and Applications brings together the diverse range of research in this important area which leads to clinical and industrialized products. The volume, num focuses on marine carbohydrates in isolation, biological, and biomedical applications and provides the latest trends and developments on marine carbohydrates.

Macroalgae species which have the highest polysaccharide content are Ascophyllum (%), Porphyra (%) and Palmaria (%). High carbohydrate content of algal species are presented in Table 3. Brown algae are rich sources of bioactive compounds such as polysaccharides, peptides, omega‐3 fatty acids, carotenoids, phenolics, vitamins and minerals.

Laminarin is low‐molecular‐weight polysaccharide and bioactive compound present in brown algae. Laminarin is found in the fronds of Laminaria and Saccharina species.

The Handbook of Macroalgae: Biotechnology and Applied Phycology describes the biological, biotechnological and the industrial applications of seaweeds. Vast research into the cultivation of seaweeds is currently being undertaken but there is a lack of methodological strategies in place to develop novel drugs from these sources.

This book aims to rectify this situation, providing an. Seaweed Polysaccharides: Isolation, Biological, and Biomedical Applications examines the isolation and characterization of algal biopolymers, including a range of new biological and biomedical applications.

In recent years, significant developments have been made in algae-based polymers (commonly called polysaccharides), and in biomedical applications such as drug delivery, wound dressings. The international research team deciphered the way the marine bacteria Formosa agariphila degrades the polysaccharide ulvan, which is produced by the algae.

Our recent studies conducted on marine algal biologically active compounds have shown anti-platelet and anticoagulant proteins and fibrinolytic enzymes. Therefore, algal polysaccharides and proteins have attracted the attention of biomedical scientists. This article provides a short review of algal anticoagulants and recent developments in this.

It is largely unknown how marine bacteria degrade algal polysaccharides. Elucidating the enzymes involved in Ulvan degradation is not only of great value for future biotechnological applications.

The inhibitory effect of brown algal phlorotannins on hyaluronidase was evaluated by an in vitro assay. Crude phlorotannins from the brown algae Eisenia bicyclis and Ecklonia kurome had a stronger inhibitory effect than well‐known inhibitors such as catechins and sodium cromoglycate.

Enzymatic technologies for marine polysaccharides. [Antonio Trincone;] -- The bioactivity potential of marine polysaccharides has long been considered an underexploited aspect. These molecules found in seaweed, microalgae, bacteria, and animal fish (shellfish, mollusks. Marine algae in the world's oceans store huge quantities of CO2, binding approximately as much CO2 per year as all land vegetation.

In this process, algae produce large amounts of carbohydrates.
