摘要
检测表明，单以紫外线或１３０℃干热作用５分钟，对被面大肠杆菌杀灭率分别为７２．６３％与９４．００％，对金黄色葡萄球菌杀灭率分别为７０．６７％与９０．０６％，对枯草杆菌黑色变种芽胞分别为４３．５３％与６３．３４％。以紫外线与１２０℃干热共同作用５分钟，对前２种细菌繁殖体杀灭率达１００％；与１６０℃干热共同作用７分钟，对上述细菌芽胞，杀灭率达９９．９１％。
It was indicated in test that exposure to ultraviolet rays or 130℃ dry heat alone for 5 min killed 72.63% and 94.00% of Escherichia coli on the surface of cotton-wadding quilt, 70.67% and 90.06% of Staphylococcus aureus and 43.53% and 63.34% of spores of Bacillus subtilis var. niger, respectively. Exposure to combined action of ultraviolet rays and 120℃ dry heat for 5 min killed 100% of the vegetative forms of the first 2 kinds of bacteria and exposure to combined action of ultraviolet rays and 160℃ dry heat for 7 min killed 99.91% of spores of above bacteria.
