Fig. 2From: Continuous degradation of phenanthrene in cloud point system by reuse of Sphingomonas polyaromaticivorans cellsEffect of cells age on biodegradation of phenanthrene. S. polyaromaticivorans was inoculated into 30 LB medium in a 150-mL flask and cultured at 30 °C and 160 rpm. Cells were collected after 4, 10, 18, 24, and 48 h of culture, respectively, and then inoculated in CPS to degrade phenanthrene for 5 daysBack to article page
