The effect of several gaseous environments on the multiplication of organisms isolated from vacuum‐packaged beef

Abstract
Summary: Cubes of sterile beef were inoculated with pure cultures of Gram positive and Gram negative organisms isolated from vacuum‐packaged beef and were stored in gaseous atmospheres containing different proportions of air, CO2 and O2 at 0 and 5°C. Generally the rate of multiplication decreased and the lag phase increased in increasing levels of CO2, but Gram positive species were more resistant to the effect of CO2 than were Gram negative organisms.
