ABSTRACT
In this study, we assessed the effects of 11-day exposure of sulfadiazine (SD), sulfamethazine (SM2), norfloxacin (NOR), and enrofloxacin (ENR) on the growth, chlorophyll a (Chl. a) content, phycobiliproteins (PBPs) content, and alkaline phosphatase (ALP) activity of Chrysosporum ovalisporum, examined the removal rate of these antibiotics by C. ovalisporum, and performed acute toxicology test with Daphnia magna to determine the effect of interaction between antibiotics and cyanobacteria on aquatic animals. The results showed that the stress of SD and SM2 increased extracellular ALP activity and weakly inhibited the algal growth and the contents of Chl. a and PBPs compared with that noted in the control. ENR and NOR treatment groups exerted significant inhibition on algal growth as well as Chl. a and PBPs contents and ALP activity, although the cyanobacterium could degrade these two antibiotics more than SD and SM2. The results also revealed that the interaction between antibiotics and cyanobacteria could inhibit D. magna feeding.
