FIG. 3.

Mineralization of BaP by P. saccharophila P15 (a) and S. yanoikuyae R1 (b). Each strain was incubated alone (▴) or in the presence of 155 μM PYRdHD (●) or 1.6 μM PYRQ (○). Data are means and standard deviations of triplicate measurements at each time point. Unobservable error bars are within the size of the symbol. Total recoveries of ¹⁴C ranged from 79 to 99% for strain P15 and from 95 to 99% for strain R1.
