Biosynthetic Structural Proteins with Super Plasticity, Extraordinary Mechanical Performance, Biodegradability, Biocompatibility and Information Storage Ability

Abstract

Degradable bioplastics have attracted growing interest worldwide. However, it is challenging to develop bioplastics with a simple processing procedure, strong mechanical performance, good biocompatibility, and adjustable physicochemical properties. Herein, we introduced structural proteins as building blocks and developed a simple environmentally friendly approach to fabricate diverse protein-based plastics. A cost-effective and high-level production approach was developed through batch fermentation of Escherichia coli to produce the biomaterials. These bioplastics possess super plasticity, biocompatibility, biodegradability, and high resistance to organic solvents. Their structural and mechanical properties can be precisely controlled. Besides, high density information storage and hemostatic applications were realized in the bioplastic system. The customizable bioplastics have great potential for applications in numerous fields and are capable to scale up to the industrial level.

Integrated Biorefinery Design with Techno‐Economic and Life Cycle Assessment Tools in Polyhydroxyalkanoates Processing

“…[ 1–4 ] To cope with these global challenges, there is an urgent need to substitute fossil‐based plastics with environment‐friendly and bio‐based plastics from renewable resources. [ 5 ] Among various available bioplastics, polyhydroxyalkanoates (PHAs) have received more attention in both academic and industrial research fields because of their biodegradability in soil and marine environment at ambient conditions, [ 6,7 ] and have shown great potential as a green replacement for fossil‐based plastics. [ 8–10 ] Notably, emerging PHAs bioplastics with green features are continued to make incursions into the commercial market, which is expected to be worth USD 28 billion tons by 2025.…”
