(A) The accumulation of 0.25 μg/ml of [125I]PG-1 by strain FA19 in the absence of CCCP (•—•), after CCCP addition (○—○) or after glucose addition to the CCCP-treated culture (○- - -○); the time points of these additions are shown. (B) The accumulation of [125I]PG-1 (0.25 μg/ml) by isogenic strains FA19 (•—•) and KH14 (○—○). All values were calculated as nanomoles of PG-1 accumulated per 107 cfu.
