Fig. 1From: Continuous degradation of phenanthrene in cloud point system by reuse of Sphingomonas polyaromaticivorans cellsThe metabolites of phenanthrene in cells and CPS. a Control system; b CPS. The biodegradation of phenanthrene was carried out in 30 mL MSM in 150-mL shaking flask at 30 °C and 160 rpm for 5 days in control and CPS by S. polyaromaticivorans, respectively. Then, cells were harvested by centrifuge at 4 °C and 8000 rpm in the control (a) or CPS (b). The distribution of metabolite in both systems was shown in the figureBack to article page
