5.1 Introduction

Biopolymers are divided into two groups according to their origin: synthetic and natural biopolymers. Polyesters, polysaccharides, and proteins are three classes of native biopolymers. For example, collagen, keratin, and elastin gluten protein are biopolymers while chitin, cellulose, and chitosan are polysaccharide biopolymers. In polysaccharide biopolymers, glycosidic bonds are bonded to monomeric saccharides [1, 2]. Biopolymers are polymeric compounds derived from living organisms, including monomers such as monosaccharides, nucleic acids, and amino acids [3, 4]. There are two ways to produce biopolymers: monomer synthesis and polymerization. Figure 5.1 shows the production of biopolymers. In particular, the design of microbial biopolymers requires C, N, salts, and other minerals.
