摘要：
Recent development of atmospheric pressure glow discharge was compared with the performance of an apparatus used in the first APG experiment, in terms of sterilization of newly classified biological indicator: Bacillus atrophaeus, former Bacillus subtilis var niger and Geobacillus stearothermophilus. Stabilization was attained by controlling the experimental conditions, at low frequency: 100 kHz and Radio Frequency: 13.56 MHz, water vapor/He dilution. Large volume of meta-stable atomic helium is responsible for the result that aids generation of hydroxyl radicals. (c) 2004 Elsevier B.V. All rights reserved.
