Abstract
Polysaccharides are the most abundant industrial raw materials that have been the subject of intensive research nowadays due to their sustainable, biodegradable, and biosafety nature. In recent years, significant progress has been made in discovering and developing new algal polymers that possess novel and highly functional properties. Alginates are established among the most versatile biopolymers and 546are used in a wide range of applications; they are quite abundant in nature, since they occur both as a structural component in marine brown algae (Phaeophyceae), comprising up to 40% of the dry matter, and as capsular polysaccharides in soil bacteria. On account of their physicochemical characteristics, chemical stability, particular structure, and high reactivity, the alginate biopolymers also have an excellent selectivity and a high ability to form complexes with various heavy metals (Aravindhan et al. 2007; Ngomsik et al. 2009). The industrial applications of alginates were mainly linked to their water-retaining ability, gelling, viscosifying, and stabilizing properties. Owing to the mature industrial sector in many developed countries, the market for alginates and derivatives is observed to be growing at a modest rate. Among the various industries, the textile and food and beverage industries are still the major consumers for alginates, and this consumption is expected to grow at a healthy rate. For various reasons, researchers are exploring the possible applications of modified forms of alginates, having various structures, functions, and properties, which are synthesized via chemical and physical reactions. © 2017 by Taylor & Francis Group, LLC.
