英文摘要The removal of bisphenol A (BPA) in seawater using microalgae is still a challenge due to the low removal efficiency and weak tolerance. A novel Oocystis algal strain was isolated for BPA removal with an efficiency (> 98%) over two times higher than that of the common microalgae Chlorella (42.8%). The maximal carbon capture rate of Oocystis was 0.16 g/(Ld) which was much higher than that of Chlorella (0.06 g/(Ld)). The BPA removal fitted a first-order kinetic model and Oocystis showed a maximum removal rate of 29.80 mu g/(Ld) at a BPA concentration of 2000 mu g/L. The new Oocystis strain had a wide range of pH adaptability for BPA removal. The sharp increase in peroxidase (POD) activity indicated its involvement in BPA degradation. Transcriptome analysis showed that BPA mainly affected the photosynthesis-related genes while the engagement of glutathione POD in the BPA biodegradation was confirmed. BPA could also serve as growth promoter for Oocystis during the removal process, which subsequently enhanced the growth and carbon capture. BPA could be removed by the Oocystis strain through hydroxylation, demethylation, and conjugation. The Oocystis strain still maintained high BPA removal efficiency (100%) and carbon capture rate (0.2 g/(Ld)) in the pilot-scale tailwater treatment system, illustrating microalgal processes were efficient for marine pollution control. This study also provides new ideas for developing low-cost carbon capture technologies to achieve the goal of carbon neutrality.
