N2 - All four Chlorella species, including one commercially available species, Chlorella vulgaris and three local isolates, Chlorella sp. (1uoai), Chlorella sp. (2f5aia) and Chlorella miniata (WW1), had a rapid and high ability to remove nonylphenol (NP). Among these species, C. vulgaris had the highest NP removal (nearly all NP was removed from the medium) and degradation abilities (more than 80% of NP was degraded) after 168h, followed by WW1 and 1uoai; 2f5aia had the lowest NP degradation ability. The NP removal by C. vulgaris was less affected by growth conditions, but its biodegradation efficiency was significantly increased by temperature and light intensity, suggesting that the biodegradation ability was positively related to photosynthetic and metabolic activities. These results indicated that C. vulgaris was the most suitable species for effective removal and biodegradation of NP, especially under 25°C with light illumination and initial biomass between 0.5 and 1.0mgchlorophylll -1.
