dc.description.abstract | The extensive contamination of levofloxacin (LEV) in aquatic ecosystems has attracted increasing attention because of the potential for development of bacterial resistance and its eco-toxicity to non-target organisms. Biodegradation of LEV was significantly improved upon the acclimation of a freshwater microalga, Chlorella vulgaris and in the presence of elevated salinity. Among the six wild species (Chlamydomonas mexicana, Chlamydomonas pitschmannii, Chlorella vulgaris, Ourococcus multisporus, Micractinium resseri, Tribonema aequale), C vulgaris showed the highest removal capacity (12%) of LEV at 1 mg L-1. The acclimated C vulgaris, which was pre-exposed to 200 mg L-1 of LEV for 11 days, exhibited enhanced removal of 1 mg LEV L-1 by 16% after 11 days of cultivation. The addition of 1% (w/v) sodium chloride into the microalgal media significantly improved LEV removal by > 80% in the C vulgaris culture. The bioaccumulation of LEV at day 11 in C vulgaris cells without NaCI was 34 rg g-1, which was elevated to 101 mu g g(-1) LEV at 1% NaCl. The bioconcentration factor for LEV was 34 and 1004 in 0 and 1% NaCl, respectively. The mass balance analysis of LEV showed that more than 90% of LEV was biodegraded by C vulgaris at day 11 with the addition of 1% NaCI. These results demonstrated that the enhanced removal of LEV by salinity was mainly through bioaccumulation and subsequent intracellular biodegradation by C vulgaris cells. | - |
