Residual effect of storage in an elevated carbon dioxide atmosphere on the microbial flora of rock cod (Sebastes spp. )
A residual inhibitory effect on microbial growth due to modified-atmosphere (MA) storage (MA, 80% CO/sub 2/-20% air) was demonstrated for rock cod fillets stored in MA and transferred to air at 4/sup 0/C. Results of measurements of CO/sub 2/ concentrations of the fillets suggested that the residual effect after transfer from MA to air was not due to retention of CO/sup 2/ at the surface of the fillets but was probably due to the microbial ecology of the system. Lactobacillus spp. and tan Alteromonas spp. (TAN) predominated after 7 and 14 days of storage in MA. During storage in MA, Pseudomonas spp. were inhibited or killed. Following transfer from MA to air, the percentage of the total flora represented by Lactobacillus spp. and TAN bacteria decreased, and 6 days after transfer Pseudomonas spp. were again dominant.
