Tli is required for Tle-mediated growth inhibition. (A) Cell extracts from the indicated ECL strains were subjected to immunoblot analysis using polyclonal antisera against the Tle lipase domain. (B) The indicated ECL inhibitor strains were mixed with ECL Δtle Δtli target cells and spotted onto LB agar. After 4 h of coculture, inhibitor and target cells were enumerated as CFU on selective media. The competitive index equals the final ratio of inhibitor to target cells divided by the initial ratio. Presented data are the average ± standard error from three independent experiments.
