Multiplication rates of duckweed in MS medium: (A) without phenol; (B) with 500 mg L⁻¹ of phenol, (C) with 750 mg L⁻¹ of phenol, (D) with 1000 mg L⁻¹ of phenol. Numbers in the legend represent bacterial strains used in the experiment: 9—K. oxytoca, 11—Lelliottia sp., 14—K. oxytoca, 27—S. marcescens, 37—H. alvei, 43—H. paralvei, 51—S. nematodiphila. Negative control sample was represented by the duckweeds grown in sterile conditions (bacteria-free). Data represent the mean ± SE (n = 3).
