Figure 3: The growth of two microorganism strain (D1.4 [1,000 mg/liter] and D1.6 [1,500 mg/liter]) in mineral salts liquid medium. Phenol concentrations and the growth of the microorganism were determined as described in the Material and Methods. Symbols: , phenol concentrations in the culture medium at the time of inspection; , total cell numbers of bacteria at the time of inspection; , total protein concentrations at the time of inspection.
