Effect of cAMP on luminescence. (A) Specific luminescence of ES114 (wild type) grown in SWTO without (open circles) or with (filled circles) 10 mM cAMP added. (B) Specific luminescence of ES114 and Δcrp mutant JB24 grown in SWTO containing 20 mM glucose without (gray circles) or with (filled circles) 10 mM cAMP. (C) Specific luminescence of ES114, JB22 (lacIq-PA1/34-luxC), Δcrp mutant JB24, and Δcrp lacIq-PA1/34-luxC mutant DC1 grown with 20 mM glucose. Averages and standard errors were calculated from replicate flasks (n = 2).
