“…Another carbohydrate group molecule is fucoidan, which is associated with brown algal cell wall components (Phaeophyceae). Among the bioactivities derived from this molecule, the anticoagulant, antitumor, antivirus, and antioxidant properties stand out, making it attractive for pharmaceutical applications [51].…”

The proposed chapter aims to provide a more in-depth explanation of the composition of carbohydrates in microalgae biomass, focusing on separation methods, chemistry, molecular characterization, as well as their application in several areas. The purpose of this review chapter is to show that biological products from microalgae have potential in health, food, and industry applications (materials and biofuel production). Steps for extraction and purification will be discussed, as well as the relationship between the type of microalgae and its composition, as a way of optimizing protocol selection and product making, without breaking down the cell to begin with (total carbohydrate extraction present in the cell). An overall overview of the current and prospective trends and methodologies for the use of microalgae carbohydrate will be included as starting points to shed light on some of the possible issues that currently do not allow the development and feasibility of microalgae biorefineries.

“…The mechanical methods include high-pressure and high-speed homogenization, bead mills, and pulsed electric field, microwave and ultrasound assistance, or autoclave. The nonmechanical action comprises freezing, organic solvents, and osmotic shock and acid, base, and enzyme reactions (Demuez, Mahdy, Tomás-Pejó, González-Fernández, & Ballesteros, 2015;Gerde, Montalbo-Lomboy, Yao, Grewell, & Wang, 2012;Günerken et al, 2015;Khanra et al, 2018).…”

Microalgae for integrated food and fuel production

2018

Microalgae have a great potential for the sustainable production of food and fuel for a growing world population with increasing demands and changing habits. Since they are cultivated in technical systems, they do not contribute to land use competition, loss of biodiversity, and environmental pollution like other food and energy crops. Despite these advantages, the commercialization of algae technology is still in an infant stage. Algae fuel production has so far failed due to low oil prices and lack of economic viability. However, integrated food and fuel production is considered promising because the food market is more diversified and open to new and innovative products than the energy market. Integrated food and fuel production from microalgae can not only achieve higher returns on investment but also greater acceptance than fuel production alone. From the sociotechnical point of view, it is however crucial that the integrated algae production system will fulfill the promises of health and sustainability. To achieve this, a codesign approach is used, considering public perception and the views, knowledge and values of citizens and stakeholders already at an early stage in the research and innovation process.

“…The global market for alginate and its derivatives was projected to be $409.2 million with a compound annual growth rate of 3.8% from 2014 to 2019 (Khanra et al., ; Rhein‐Knudsen, Ale, & Meyer, ). Both algae and bacteria synthesize alginate and are alginate sources.…”

“…Laminaria hyperborean , Macrocystis pyrifera , Laminaria digitata , and Ascophyllum nodosum are species commonly used for commercial alginate production. When the above mentioned species are unavailable, Sargassum spp., Laminaria japonica , Ecklonia maxima , and Lessonia nigrescens can be utilized, though alginate yield is usually lower and quality is inferior (Khanra et al., ). While cultures of bacterial alginate producing species Azotobacter and Pseudomonas produce alginate, such production is usually confined to small‐scale research studies (Skjaak‐Braek, Grasdalen, & Larsen, ).…”

They are also crucial for alginate physicochemical properties, including viscosity, sol/gel transition properties, water uptake, and so on (Khanra et al, 2018). Alginates rich in GG blocks have higher water solubility than those rich in MM blocks (Jimenez-Escrig & Sanchez-Muniz, 2000).…”

Alginate, a group of polyuronic saccharides, has been widely used in both pharmaceutical and food industries due to its unique physicochemical properties as well as beneficial health effects. However, the potential applications of alginate are restricted because of its low water solubility and high solution viscosity when significant concentrations are needed, particularly in food products. Alginate oligosaccharides (AOS), oligomers containing 2 to 25 monomers, can be obtained via hydrolysis of glycosidic bonds, organic synthesis, or through biosynthesis. Generally, AOS have shorter chain lengths and thus improved water solubility when compared with higher molecular weight alginates of the same monomers. These oligosaccharides have attracted interest from both basic and applied researchers. AOS have unique bioactivity and can impart health benefits. They have shown immunomodulatory, antimicrobial, antioxidant, prebiotic, antihypertensive, antidiabetic, antitumor, anticoagulant, and other activities. As examples, they have been utilized as prebiotics, feed supplements for aquaculture, poultry, and swine, elicitors for plants and microorganisms, cryoprotectors for frozen foods, and postharvest treatments. This review comprehensively covers methods for AOS production from alginate, such as physical/chemical methods, enzymatic methods, fermentation, organic synthesis, and biosynthesis. Moreover, current progress in structural characterization, potential health benefits, and AOS metabolism after ingestion are summarized in this review. This review will discuss methods for producing and modified AOS with desirable structures that are suited for novel applications.
