Abstract

In the recent decades, biopolymers have received considerable attention due to their renewability, broad availability and biodegradability. Scientists concerned with antimicrobial biopolymers as an alternative to petroleum-derived polymers for implementing in several substantial applications such as food packaging, seeds preservations, wound dressing, cell culture and tissue engineering.
In the current study, cinnamyl chitosan Schiff base membranes were prepared by using different amounts of tween 20 (T20) as a plasticizer. A comparative study was carried out to illustrate the effect of T20 on the prepared membranes including their physical, surface morphologies, optical and mechanical properties. In addition, the antibacterial activities were also investigated against five bacterial strains (two Gram-positive: Streptococcus pyogenesand Staphylococcus aureus& three Gram-negative: Proteus vulgaris, Pseudomonas aeruginosa, and Shigella sp.). The gained results revealed higher antibacterial activities cinnamyl chitosan compared to native chitosan membranes. Moreover, treatment of cinnamyl chitosan with different concentrations of T20 significantly enhanced the antibacterial activities of the membranes. Almost various concentrations of T20 showed identical antibacterial activities depending on the bacterial strain.
