The effects of atmospheres containing 20% O and 0 to 80% CO or 30% CO and 0 to 40% O (balance N) on the growth rate and lag phase of Listeria monocytogenes and Pseudomonas fluorescens in buffered nutrient broth at 7.5°C were investigated. Increasing CO concentration lengthened the lag phase and decreased the growth rate of both organisms. CO levels above 20% significantly reduced the growth rate of P. fluorescens and CO levels of 80% significantly reduced the growth rate of L. monocytogenes . Linear and multiple regression analyses were used to describe L. monocytogenes and P. fluorescens growth curves. The values of all regression analyses were greater than 93%. The regression equations indicate that CO inhibits the growth of both P. fluorescens and L. monocytogenes even in the presence of 20% O, However, the effect of CO on P.fluorescens is greater than on L. monocytogenes .
研究了含有20%氧气和0至80%二氧化碳或30%二氧化碳和0至40%氧气（其余为氮气）的气氛对7.5°C缓冲营养肉汤中单核细胞增生李斯特菌和荧光假单胞菌生长速率和延迟期的影响。增加二氧化碳浓度会延长两种微生物的延迟期并降低其生长速率。20%以上的二氧化碳水平显著降低了荧光假单胞菌的生长速率，80%的二氧化碳水平显著降低了单核细胞增生李斯特菌的生长速率。使用线性和多元回归分析来描述单核细胞增生李斯特菌和荧光假单胞菌的生长曲线。所有回归分析的R值均大于93%。回归方程表明，即使在存在20%氧气的情况下，二氧化碳也会抑制荧光假单胞菌和单核细胞增生李斯特菌的生长，然而，二氧化碳对荧光假单胞菌的影响大于对单核细胞增生李斯特菌的影响。
