Isolation and Identification of the Strains Producing Alginase, Purification, Characterization and Enzymatic Degradation of the ALY-SJ02 Cloning and Expression of the Alginase GeneCompanyLOGOSupervisor: Prof. Xiulan Chen Prof. Yuzhong Zhang 8. Background Alginates are synthesized as cell wall components by brown seaweeds and as exo-polysaccharides by two families of heterotrophic bacteria, Pseudomonadaceae and Azotobacteriaceae.Alginate is widely used as a stabilizer, viscosifier, and gelling agent in the food and beverage, cosmetics, paper and printing, biomaterials, and pharmaceutical industries. 9. Background Alginate is an acidic linear polysaccharide composed of (14)-linked -L-guluronate (G) and its C5 epimer -D-mannuronate (M); the uronic acids are arranged in three types of block structures, homopolymeric polyguluronate (PG), homopolymeric polymannuronate (PM), and heteropolymeric sequences of randomly distributed the residues (PMG), which are named G-blocks, M-blocks, and MG-blocks, respectively. Alginates can be degraded by alginate lyases (alginases) which usually catalyze the cleavage of the glycosidic linkages via a elimination mechanism. Polysaccharide lyases are classified into 18 families (PL-1 to -18). Alginate lyases mainly occupy two families (PL-5 and -7). 10.
