Relationship between carbon dioxide production and growth of pure strains of bacteria on porcine muscle.

Abstract

SUMMARYThe 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 CO2 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 CO2 than the Gram positive organisms. Data on the effects of CO2 on the growth of each bacterium at 16 and 2° are presented.
