Proteins can act as suitable gas barrier layers in packaging, offering a biodegradable alternative to ethylene vinyl alcohol, however, protein-rich microbial biomass sources for bioplastics remain underexplored. Here, the authors develop bioplastic films and trays from bacterial biomass produced using liquid side streams from the potato processing industry, demonstrating its oxygen barrier properties for packaging applications.
