Enhancement of degradation of acrylamide coupled with salad oil by Pseudomonas aeruginosa DS-4 using incubation periods

Lipid wastewater may contain carcinogenic compounds that are formed mainly from cooking oils. Prolonged exposure to these compounds tends to increase cancer risk in humans. In this study, an efficient strain capable of degrading both oil and acrylamide was isolated. Pseudomonas aeruginosa DS-4 was cultivated in 4 g L−1 salad oil. The degradation rate of acrylamide was affected by the incubation time of the acclimated strain DS-4; a longer incubation time with later acrylamide additions resulted in more efficient degradation. If the salad oil was removed, the strain could not grow, and the acrylamide was not degraded.
