Figure 1. Relative survival of nine Aeromonas strains co-cultured with T. thermophila in three different proportions.
Relative survival of each bacterium at 12 h is expressed as the number of Aeromonas CFU in the co-culture with T. thermophila relative to the number of Aeromonas CFU grown alone. At the start of the experiment, T. thermophila was at 1×105 cells/ml while the Aeromonas spp. was at 1×108 CFU/ml (A), 5×108 CFU/ml (B) and 1×109 CFU/ml (C), respectively. Error bars represent standard deviations from four independent experiments, with each experiment being comprised of four individual measurements.
