Relationship between Carbon Dioxide Production and Growth of Pure Strains of Bacteria on Porcine Muscle

Abstract

SUMMARY The growth of a Pseudomonas sp., an Enterobacter sp., Kurthia zopfii, Microbacterium thermosphactum and a Lactobacillus sp. in pure culture on porcine muscle at 16 and 2° was examined in both open and gas‐tight systems. The CO 2 in the headspace of the gas‐tight containers was produced by the muscle and by the bacteria. The Gram negative bacteria produced much lower amounts of CO 2 than the Gram positive organisms. Data on the effects of CO 2 on the growth of each bacterium at 16 and 2° are presented.
