This research reports about the development by electrospinning of fiber-based films made of
poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) derived from fermented fruit waste, so-called
bio-papers, with enhanced antimicrobial performance. To this end, different combinations of oregano
essential oil (OEO) and zinc oxide nanoparticles (ZnONPs) were added to PHBV solutions and
electrospun into mats that were, thereafter, converted into homogeneous and continuous films of
~130 µm. The morphology, optical, thermal, mechanical properties, crystallinity, and migration
into food simulants of the resultant PHBV-based bio-papers were evaluated and their antimicrobial
properties were assessed against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) in both
open and closed systems. It was observed that the antimicrobial activity decreased after 15 days due
to the release of the volatile compounds, whereas the bio-papers filled with ZnONPs showed high
antimicrobial activity for up to 48 days. The electrospun PHBV biopapers containing 2.5 wt% OEO +
2.25 wt% ZnONPs successfully provided the most optimal activity for short and long periods against
both bacteria. [-]
