Fig 1. Antibacterial activities of V. alginolyticus T6SSs are differentially regulated by salinity and temperature.

Viability of E. coli prey before (0h) and after (4h) co-culture with indicated V. alginolyticus attacker strains or alone. Co-cultures were incubated for 4 hours on (A) LB or (B) MLB agar plates at 30°C or 37°C. None = medium only. WT = wild-type.
