FIG. 6.

Time course of production of ROS, GroEL, and polyP in Pseudomonas sp. strain B4. (A) Exponentially grown cells were shifted from a defined medium supplemented with glucose to a medium supplemented with 2-chlorobiphenyl (▵ and ○) as the sole carbon source. Control cells were maintained in a medium containing glucose (▴ and •). GroEL levels (• and ○) and ROS production (▵ and ▴) were measured as described in the text. (B) polyP content of cells shifted from a defined medium supplemented with glucose to a medium supplemented with 2-chlorobiphenyl (○), glycerol (▴), or glucose (▪) as the sole carbon source. FU, fluorescence units.
