不同水分活度(Aw，0.005~0.996)处理的枯草芽孢杆菌芽胞，在开放系统干燥条件下，用0.5kW和1.0kW的红外线辐射加热灭活。枯草杆菌孢子对赤霉病的抗性在0.874~0.25Aw范围内较大，在0.5kW和1.0kW时达到最大值，分别为0.796和0.688。在较低或较高的Aw水平下，枯草杆菌孢子对IRH的抗性明显降低。
Bacillus subtilis spores pretreated at various water activities (aw, from 0.005 to 0.996) were inactivated by infrared radiation heating (IRH) at 0.5 and 1.0 kW of electric power under dry conditions in an open system. The resistance of B. subtilis spores to IRH was greater in the range of 0.25 to 0.874 aw, and had the maximum value when aw was 0.796 at 0.5 kW and 0.688 at 1.0 kW. Markedly lower IRH resistance of B. subtilis spores was observed at the lower or higher levels of aw.
