Comparison of anti-S. Enteritidis effects of viable lactobacilli or lactobacilli cell-free supernatant. While viable lactobacilli efficiently inactivated S. Enteritidis during co-culture irrespective of the initial ratio of lactobacilli to S. Enteritidis shown in µL (shades of red), cell-free supernatants from 2- or 3-day-old lactobacilli culture were ineffective against S. Enteritidis, irrespective of whether 100 or 1000 µL of S. Enteritidis was used for inoculation (shades of blue). If only S. Enteritidis was used for moistened-feed inoculation, it grew on this substrate up to 10¹⁰ CFU/g of feed (green column).
