coli suggest that TBX may underestimate the number of HHP-injured bacteria.Ĭitation: Justyna Nasiłowska, Barbara Sokołowska, Monika Fonberg-Broczek. The recovery of sublethally injured cells on ALOA and TAL did not differ statistically in every strain. The regeneration was observed exclusively for L. In both used methods, the possibilities of recovery were provided. Additionally, the Thin Agar Layer (TAL) method was applied.
According to two standardized ISO methods, selective conventional agars, TBX, and ALOA were used in the storage test. Sublethal injuries in the bacterial population were observed for all tested strains. coli strains displayed resistance to pressure, and the maximum reduction achieved was 2 log CFU/mL for the harshest process parameters. innocua strains starting from 400 MPa for 5 min. Required 5 log reduction was achieved only for L. The number of bacteria in the populations was analyzed using plating count methods.
Samples were processed with different variants of pressure (300,400,500) and time (1 min, 5 min, and 10 min).
