FIG. 3.

Growth and degradation of trihalogenated propanes by A. radiobacter AD1(pTB3). Cultures were grown aerobically at room temperature in MMY medium supplemented with 1 mM 1,2,3-tribromopropane (4 pulses), 1.2 mM 1,2-dibromo-3-chloropropane (2 pulses), or 1.6 mM 1,2,3-trichloropropane as carbon source. (A) 1,2,3-Tribromopropane (○), 2,3-dibromo-1-propanol (●), OD₄₅₀ (▴); (B) 1,2-dibromo-3-chloropropane (○), 2-bromo-3-chloro-1-propanol (●), OD₄₅₀ (▴); (C) 1,2,3-trichloropropane (○), 2,3-dichloro-1-propanol (●), OD₄₅₀ (▴); (D) (sterile controls) 1,2,3-tribromopropane (●), 1,2-dibromo-3-chloropropane (▿), 1,2,3-trichloropropane (■).
