Marine macroalgae, in distinct, are important food sources in the coastal regions of East Asia such as China, Korea, Japan, and Indonesia [1]. The international industrial seaweed industry was calculated at USD 5.9 billion in 2019 and is Thromboxane B2 Epigenetic Reader Domain anticipated to a compound annual growth rate of 9.1 [2]. Well being benefits of seaweed food and snack goods are gaining spotlight as vegan sources of protein, lipid and carbohydrates, and demand is expected to enhance both for consumption and for additional applications. By way of example, microalgae polysaccharide extracts are utilized as thickening and gelling agents within the cosmetic and meals industries, and the demand is developing particularly in North America and Europe [3]. Amongst their lots of utilizes, the portion straight consumed (excluding thickeners and hydrogels utilized in food and beverage processing) alone have reached 24 million tons per year, accounting for about 40 in the annual seaweed production [4]. Indeed, the idea of seaweed as healthy food is deeply rooted in a lot of people’s minds. Although new applications of polysaccharides derived from marine algae are regularly being discovered, the raising awareness of this ecofriendly, organic, and environmentally sustainable food source additional promotes its consumption. Macroalgae are also used in biorefineries; the carbohydrates are converted to high-value AS-0141 Inhibitor byproducts with metabolic engineering approach [5]. The prospects of algae as green, healthful meals, along with a bioresource is becoming actively explored. Macroalgae are classified into green, red, and brown algae [6]. Brown algae is comprised of 20 classes; the class Phaeophyceae alone accounts for more than 1800 species and 66Mar.

One of the most typical species are the kelps Laminaria (kombu), Undaria (wakame), and Macrocystis [8]. The polysaccharides alginate, laminarin, and fucoidan (Figure 1) account for more than 50 from the total dry weight of brown algae, and can attain up to 70 in some species. Cellulose will be the only crystalline element which has been reported in the walls from brown algae so far and it only occurs at 1 of algal dry weight [9].Mannitol exists i.
