Growth rates of the Aba, SS1, and GS1 strains. p was 0.0315 at 8 hr. SS1, GS1, and Aba strains were cultured in 15 ml LB medium at 37°C for 24 hr with agitation. The optical density at 630 nm was measured using 200 μl of SS1, GS1, and Aba strains every 2 for 24 hr. The experiment was repeated three times
