Three fluorocarbons were tested to determine their effect on bacterial growth. Freon 11 and 21 in various concentrations had an inhibitory effect on selected test organisms, but Freon 22 had no effect. Both aerobic and anaerobic microorganisms, as well as gram-positive and gram-negative species, were included among the bacteria tested. Freon 11 and 21 caused a similar response with Freon 11 being more inhibitory to some species and Freon 21 more inhibitory to others. Inhibition was dependent on the concentration of the halocarbon and resulted in decreased respiration rates at all concentrations tested. Results reported here indicate that the action of the fluorocarbons tested is bactericidal rather than bacteriostatic, Serratia marcescens and Clostridium botulinum were the species most sensitive to the halocarbons tested.
测试了三种碳氟化合物以确定它们对细菌生长的影响。不同浓度的氟利昂11和21对选定的测试生物有抑制作用，但氟利昂22没有效果。所测试的细菌包括需氧和厌氧微生物，以及革兰氏阳性和革兰氏阴性菌。氟利昂11和21引起了类似的反应，氟利昂11对某些物种的抑制作用更强，而氟利昂21对其他物种的抑制作用更强。抑制作用取决于卤代烃的浓度，并且在所有测试浓度下均导致呼吸速率降低。此处报告的结果表明，所测试的碳氟化合物的作用是杀菌而非抑菌，粘质沙雷氏菌和肉毒梭菌是对所测试的卤代烃最敏感的物种。
