Table 1.
The concentration of cefradine in the first and second treatment batches.
Fig 1.
The population growth inhibition rate of C. pyrenoidosa in a sequencing batch reactor alga process (SBAR) to remove cefradine.
(A) The inhibition rate in the first treatment batch at three concentrations (10, 30 and 60 mg/L). (B-D): The inhibition rate in the second treatment batch at two concentrations (30 and 60 mg/L) after a first treatment batch at 10 mg/L, 30 mg/L or 60 mg/L.
Fig 2.
The chlorophyll content of C. pyrenoidosa in the first treatment batch of cefradine at three concentrations (10, 30 and 60 mg/L).
(A) Chlorophyll-a content. (B) Chlorophyll-b content. Algae with under 0 mg/L of the antibiotic were used as the no treatment group.
Fig 3.
The chlorophyll content of C. pyrenoidosa in the second treatment batch.
(A) The chlorophyll-a content of the algae in the second treatment batch at two concentrations (30 and 60 mg/L) after a first treatment batch at 10, 30 and 60 mg/L. (B) The chlorophyll-b content of the algae in the second treatment batch at two concentrations (30 and 60 mg/L) after a first treatment batch at 10, 30 and 60 mg/L. Algae with 0 mg/L of the antibiotic was used as the no-treatment group.
Fig 4.
The removal rate of cefradine by C. pyrenoidosa.
(A) In the first treatment batch. (B) In the second treatment after a first treatment batch at 10 mg/L. (C) In the second treatment after a first treatment batch at 30 mg/L. (D) In the second treatment after a first treatment batch at 60 mg/L.
