Influence of Q-SUN Irradiation on Antimicrobial and Antiviral Activity of Tea Tree Oil-Based Coatings on Polypropylene Films
Source abstract
Abstract
The study investigated the antimicrobial and antiviral effects of polypropylene foil coated with hydroxypropyl methylcellulose (HPMC) layer containing tea tree oil (TTO) as the active agent. Moreover, the influence of accelerated aging using Q-SUN treatment on the efficacy of the non-coated and coated foils was also investigated. The results of the study indicated a slight antimicrobial effect of the irradiated coating against S. aureus, noticeable antibacterial activity of both irradiated and non-irradiated coating against E. coli and a complete inhibition of B. cereus growth by the irradiated coating. However, both of these coatings exhibited strong antiviral properties, confirmed by a method consisting of two separate tests conducted on the Φ6 phage as the infectious agent: real-time measurement of the host’s OD during co-culture with the phage and observation of the host’s growth on copper mesh grids using scanning electron microscopy (SEM). The characteristics of non-irradiated and irradiated foils were also determined using SEM and FT-IR.
