Comparison of significant frequencies from the Fourier spectra in the cultures treated with norfloxacin. The amplitudes of the most significant frequencies have been compared using the two-tailed Student's t-test; the asterisks mark the frequencies whose power was significantly different (p < 0.05) from the power of the corresponding frequencies in the spectrum from the untreated cells (0 min).
