The effect of carbon dioxide on the viability of bacteria of Bacillus and Diplococcus genera

The effect of the volume of carbon dioxide gas released from aqueous solution on the reduction of the number of vegetative microorganisms per unit volume of the system has been investigated. A linear relationship between the number of vegetative microorganisms and the volume of released carbon dioxide is observed, when the volume of the released gas does not exceed the level of 0.5 dm3/dm3 of solution. The increasing ratio of the amount of spores to the number of vegetative bacteria of Bacillus genus results in a largely reduced impact of the volume of released carbon dioxide on the microbial viability.
