abstract |
Atmospheric pressure plasmas have gained attention in recent years for several environmental
applications. This technology could potentially be used to deactivate airborne microorganisms,
surface-bound microorganisms, and biofilms. In this work, the authors explore the
efficacy of the atmospheric pressure dielectric barrier discharge (DBD) to inactivate
airborne <i>Staphylococcus epidermidis</i> and <i>Aspergillus niger</i> that are opportunistic
pathogens associated with nosocomial infections. This technology uses air as the source
of gas and does not require any process gas such as helium, argon, nitrogen, or hydrogen.
The effect of DBD was studied on aerosolized <i>S. epidermidis</i> and aerosolized
<i>A. niger</i> spores via scanning electron microscopy (SEM). The morphology observed
on the SEM micrographs showed deformations in the cellular structure of both microor-
ganisms. Cell structure damage upon interaction with the DBD suggests leakage of vital
cellular materials, which is a key mechanism for microbial inactivation. The chemical
structure of the cell surface of <i>S. epidermidis</i> was also analyzed by near edge
x-ray absorption fine structure spectros- copy before and after DBD exposure. Results
from surface analysis revealed that reactive oxygen species from the DBD discharge
contributed to alterations on the chemistry of the cell membrane/ cell wall of <i>S.
epidermidis</i>. |
