Polyhydroxyalkanoates and exopolysaccharides: An alternative for valuation of the co‐production of microbial biopolymers

Abstract

Polyhydroxyalkanoates (PHAs) and exopolysaccharides (EPSs) belong to a class of abundant biopolymers produced by various fermenting microorganisms. These biocompounds have high value‐added potential and can be produced concurrently. Co‐production of PHAs and EPSs is a strategy employed by researchers to reduce costs associated with large‐scale production. EPSs and PHAs are non‐toxic, biocompatible, and biodegradable, making them suitable for various industrial sectors, including packaging and the medical and pharmaceutical industries. These biopolymers can be derived from agro‐industrial residues, thus contributing to the bioeconomy by producing high‐value‐added products. This review investigates approaches for simultaneously synthesizing PHAs and EPSs using different carbon sources and microorganisms.
