Abstract
More than 60 million tons of sulfur are produced as a byproduct of the petrochemical industry annually. Recently, the inverse vulcanization process has transformed this excess sulfur into functional polymers by stabilization with organic cross-linkers. These interesting new polymers have many potential applications covering diverse areas. However, there has been very little focus on the potential of these high-sulfur polymers for their antibacterial properties. These properties are examined here by exposing two common bacteria species, <i>Escherichia coli</i> (<i>E. Coli</i>) and <i>Staphylococcus aureus</i> (<i>S. aureus</i>), to two structurally different, inverse vulcanized sulfur polymers: sulfur-<i>co</i>-diisopropenyl benzene (S-DIB) and sulfur dicyclopentadiene (S-DCPD). We report the highest bacteria log reduction (>log 4.3) of adhered bacterial cells (<i>S. aureus</i>) to an inverse vulcanized sulfur polymer to date and investigate the potential pathways in which antibacterial activity may occur.
