Biodegradable Polymers: Renewable Nature, Life Cycle, and Applications

Microbial Factories

Abstract

Biopolymers are superior to synthetic polymer due to their eco-friendly nature. Microbial biopolymers being a good substitute for conventional plastics causing a waste management problem. Polyhydroxyalkanoates (PHAs) produced as microbial polyesters can provide promising prospects for food and allied industries due to their versatile properties assisting viscosifying, gelling, and film-forming ability. Microbial and biocatalytic production of functionalized polyhydroxyalkanoates with novel monomer structure and tailor-made properties can be feasible by manipulating the metabolic network in host microbes by genetic modification enabling them to utilize a diverse range of low-cost substrate as unsaturated fatty acid constituents. But expensive technology associated extraction and isolation of PHAs is a major hindrance for their commercial applications. A collective knowledge about PHAs as microbial biopolymers, their production from cheap and renewable resources, metabolic pathways involved in their production, economics of PHA production, and decisive factors involved could possibly assist their effective utilization as a substitute to synthetic polymers.
