Type of article: Article

Summary

The effects of atmospheres containing 20% O2 and 0 to 80% CO2 or 30% CO2 and 0 to 40% O2 (balance N2) on the growth rate and lag phase of Listeria monocytogenes and Pseudomonas fluorescens in buffered nutrient broth at 7.5 deg C were investigated. Linear and multiple regression analyses were used to describe L. monocytogenes and P. fluorescens growth curves. The R2 values of all regression analyses were greater than 93%. The regression equations indicate that CO2 inhibits the growth of both P. fluorescens and L. monocytogenes even in the presence of 20%.
