Original Abstract

The reduction or removal of the microbial contamination from paper using atmospheric pressure discharges has been studied. Aspergillus niger, the fungi commonly found in libraries and archives, was spread on Whatman paper no. 1. The fungi was cultivated on agar plates for seven days. Aftewards the paper samples were treated in dielectric barrier discharge (DBD) in nitrogen. To observe the influence of the treatment time on the microorganisms removal, the time was varied up to 150 s. Treated samples were recultivated on agar plates in order to see the sterilisation effect of plasma. Moreover the influence of the plasma treatment on the paper mechanical properties was investigated. Positive results in microorganisms inactivation were obtained for sample treated 90 s or longer. Slight decrease of paper strength was observed for the paper contaminated with Aspergillus.
