Effect of increasing concentrations of trihalogenated propanes on growth of A. radiobacter strains AD1 (●), AD1(pTB1) (▴), and AD1(pTB3) (■) growing on 5 mM 1,3-dichloro-2-propanol. The turbidity (OD450) of the cultures was measured after 7 days of cultivation at 30°C. Initial OD450 values ranged from 0.5 to 0.7. (A) 1,2,3-tribromopropane; (B) 1,2-dibromo-3-chloropropane; (C) 1,2,3-trichloropropane.
