Figure 4: The growth of microorganism strain D1.1 - 6 system and dioxin soil (D1 and D2). Mineral salts liquid medium were added to the phenol concentrations of 100 mg/liter, and after culture at 28°C, shaking speed at 150 rpm. Phenol concentrations and the gr owth of the cultured bacteria were determined as described in the Material and Methods. Symbols: , dioxin soil sample D1; , dioxin soil sample D2; , the mixture of microorganism strain (D1.1, D1.3, D1.4 and D1.6).
