Biotransformation of phenolic profiles and improvement of

Working solutions (0.4–10.0 g/L) except fumaric acid (1.0–10.0 mg/L) were obtained by diluting the standard solutions in distilled water and kept in dark bottles at 4 °C prior to use. The HPLC results were qualitatively analyzed by peak retention time and quantified by peak area using the external standard (Sigma-Aldrich, USA) method. 2.5.
