Abstract
Abstract To investigate the enhancement of phenol on the biodegradation of 4-chlorophenol (4-cp), metabolic profiling approach was performed for the first time to analyze metabolite changes of Pseudomonas sp. cbp1-3 using single substrate (succinate, phenol, and 4-cp) and dual substrate (mixtures of phenol and 4-cp). Phosphoric acid, γ-aminobutyric acid, 4-cp, 4-chlorocatechol, and catechol were shown to change significantly. Results indicated that phenols, especially 4-cp, depressed cell growth by inhibiting its primary metabolic pathway. In addition, the addition of phenol into the 4-cp-containing medium had a global influence on cells including the accumulation of amino acids, amines, saturated fatty acids, and monoacylglycerols as well as the concentration changes of metabolite participating in phenols biodegradation, thus enhancing the degradation of 4-cp. This study provided novel insights into the biodegradation of mixed phenolic compounds and the method could be used to investigate the biodegradation of complicated multi-pollutants.
