目前使用大气压辉光放电（APGD）的枯草芽孢杆菌孢子的灭活研究没有考虑两个重要因素，即基质表面的微生物负载和孢子形成温度。然而，已知这些会显著影响微生物对热和过氧化氢的耐受性。本文研究了微生物负荷和产孢温度对孢子抗APGD的影响。结果表明，微生物负载可以导致堆叠结构作为对APGD处理的保护屏障，并且高孢子形成温度通过改变B的核心水含量和交联胞壁酸含量来增加孢子抗性。枯草芽孢(C)2005年美国物理学会。
Current inactivation studies of Bacillus subtilis spores using atmospheric-pressure glow discharges (APGD) do not consider two important factors, namely microbial loading at the surface of a substrate and sporulation temperature. Yet these are known to affect significantly microbial resistance to heat and hydrogen peroxide. This letter investigates effects of microbial loading and sporulation temperature on spore resistance to APGD. It is shown that microbial loading can lead to a stacking structure as a protective shield against APGD treatment and that high sporulation temperature increases spore resistance by altering core water content and cross-linked muramic acid content of B. subtilis spores.
